73 Honda CB750 Custom Build Part 30 - Exhaust install & start up!

hey we got an exhaust system welcome to hack a week okay so the goal here in this video is get the exhaust mounted on the bike and possibly fire it up I'd really like to do that and to do that I need to get the electrical working I can fake that with my small jumper battery and I need mostly a throttle cable I can just kind of jumper wire all the stuff for the ignition that's not a big deal but I do need a throttle cable to be able to control the carburetors I don't want to just go pushing on them with my thumb I'd like to be able to give them a little crank over left to throttle up with some control so first thing I need to do is get the throttle control mounted up on the handlebars and get the cables routed where they need to be and get them connected up to the carburetor just to catch you up here I've got the bolts all in for the engine mounts there's a cross bolt that goes across here it's got some nuts on either side those have been torqued up I put a yellow dot on everything that I torqued up and let's see the foot pegs are in place I've got to still tighten these up all the way and torque them I've just got them in there and snug down for now but I want to make sure that they're in the right location and it looks like they are there's a couple of bolts that go in here they're ten millimeter and they have a nut on the other side that's a 17 millimeter wrench size on that nut and it just fits right in on the frame there and let's go to the other side there's a bracket that went on right here a couple of eight millimeter bolts that went through here through the frame and to the other side there's a couple of nuts on that back here we've got another bracket that goes to that cross bolt and then two eight millimeter bolts that thread right into that bracket it there's the other side the other foot peg that other through bolt that I need to torque down and then of course we've got to get the oil tank back on there's the place where the two lines go in oil tank mounts right in this area here I've got some rubber grommets that need to go into the oil tank rubber grommets go in here and let's see they go in here one down here I've got all that stuff in here I've got the clamps that go around these guys that go into the cylinder heads there's the gaskets I've got new bolts for these let's see what's this stuff here these are yeah these are the bolts for those and all the oil tank rubber grommets and such so now I've got a dig through a couple of boxes here somewhere up there on those shelves are some throttle cables let's find that stuff alright let's see in here should be yeah there's the there's the plastic part that the throttle cables go into that slides over the handlebar and should be some powder coated yep there's a bag of powder coated stuff that's got the housing that goes around that there's probably some screws that I got a fine for those two clutch cable let's see it looks like just take all this stuff down onto the bench okay let's take a look at what we got here oh by the way I picked up a fairly inexpensive set of JIS screwdrivers that's Japanese industrial standard they may look like Phillips but they are slightly different to the Phillips anything you work on on a motorcycle you need to set of these I finally got some much better than working with the standard Phillips screwdrivers they just fit better let's see we've got some goodies here that are going to go around this rattle handle here of course we got other stuff that goes with that okay this is the one I'm looking for this is for the throttle cable this goes in like this and that rotates like so and there's going to be a piece that goes on top of that okay so that looks like that's it right there okay there's that assembly alright first thing we got to do is get these cables routed through these holes and they only go one way this one threads into that hole we have to turn this on to the cable so let's make sure we get that threaded right come on jump in there there we go and I'm not sure how far you'll need to go but I'm just gonna probably good enough right there just to leave myself a little room to tighten the nut all right let's leave that about like that the other cable has its own little nut built on to it put that one through the hole being stubborn there we go we're set up in there and put the nut in place and we're going to tighten this all the way to the bottom but not completely tight just yet let's take it where it bottoms out right there I'll leave that a little bit loose so I can move it around okay step one done that's the only screw I have for now to hold this on good enough for now I can pick up some more later I need to spec out what size those are the way I always do by going on the website for some honda parts and print out the parts break down and I can see just what size it's supposed to be but in the meantime we're just going to put this together like this give a screw in here I'm just going to tighten this up as tight as it'll go it's still going to rotate but it's it's good enough I think for now I'll see if I can find another screw to get in there but at least we can get the cables hooked up now and check things out alright throttle cable routing we're going to bring these cables toward the front around the front of the fork tube through here and we're going to go down here underneath the coils go right between those two plug wires there and we're going to take it through this hole in the frame right here and pushing through there we go we're ready to mount them up on the cable housing holder there's the two cables now I've got the throttle let's see get the throttle in the off position as I turn the throttle back you can see which cable is pulling it's this one right here and this works open the throttle by pulling on the upper one so that's where this cable is going to go so if this one goes on top that means this one goes on the bottom so we can get this one hooked up down below first so the lug on the end of the cable that goes into the hole down there a little bit tricky to get lined up and then you want to rotate it so just goes into the slot right there now we can get the cable into the cable holder drops in there just like that we're going to tighten that up in a minute and now we have the upper cable when I rotate the throttle you can see how that one wants to pull so we're going to put that in same way look over here in the little hole get it in that slot on the throttle linkage let's give it a test here in a minute why is it there we go so let's see we're going to leave a little bit of slack in that cable that's good right there bring that nut up against there let's give it a quick test yeah that looks good that's a good starting point leaving that little bit of slack now we'll tighten up these two nuts the one down below and the two nuts here okay that one's tight this one up that's good enough for now I'll come back and tighten these better later after we get the carbs all set up and synced I'm going to leave that play in there for now I just installed the clutch cable get about that much play in it free play adjusted the adjuster here out just a little bit cable runs down here only temporary there are clamps that hold this cable in place it comes down here to this adjuster I've got that adjusted the end of it goes into the lever right there so the clutch is connected up now I want that there so I can check the gears make sure everything shifts okay when I fire this thing up I'm going to run it through some gears pull in the clutch when I do that spark plugs let's get a little bit of anti-seize lubricant on the threads of each one of these plugs I always do this on any engine that I put together is that - that's silver stuff you know you can buy it at auto parts stores now these are ready to put in the head now when I player this up it's going to be the first time for it and the piston rings are going to be seating into the cylinders and I personally like to put a little bit of Marvel Mystery Oil into each cylinder gives it a little bit of that machine oil lubricant to help it out when those piston rings are seating in and I put a pretty generous amount in there I'm going to put about three squirts now that I've got some oil in each one of the cylinders before I put the plugs in I'm going to take my Kickstarter and just slowly rotate the engine around just to move some of that oil around in the cylinders okay now what the spark plugs in is their 18 millimeter socket for these plugs these are brand new plugs you want to tighten to where you just feel a little resistance just where the washer crushes and that's good enough here's a neat little trick for putting the plugs in on the Center cylinders they're kind of hard to reach just put it on a piece of flexible fuel line push the spark plug into that and you can reach down into that hole and then just use the hose to get the plug started for you now we can connect the plug wires the coil on this side goes to cylinders one and four there's one and over here is four and then the other coil of course there's two and three time to mount up the oil tank we got the grommets in here there are let's see there's grommets in each corner those grommets are the ones for the bolts that hold the tank to the frame and there's a bevel on one side and then the other side is flat the flat side is what goes towards the frame then these grommets will hold the side cover plastic side cover on let's do this up here there's a shoulder bolt that holds all that together it's got a washer on it that pushes through the grommet so we can put those bolts in place first and they'll stay right in the ground and get our lines down here setup okay I've got the lines down where they need to go see if I can get this lined up and started if these all turned tight we'll tighten them up in a minute ratchet get the oil lines tightened to the right case the torque on these six millimeter bolts is usually nine foot-pounds I've got a pretty good feel for that with my little ratchet so I'm not going to get out torque runs this time there we go there's a breather line here that goes to the crankcase has to go to the oil tank as well and then this breather on top will eventually go to the airbox make sure that that's on there now we get to the exhaust this flange goes on here and then the exhaust pipe goes on there and a clamp goes around it with a heatsink on it the thing with the fins on it this is a copper crush gasket it's looks like an o-ring almost and it's designed to crush when you put it in there so let's put that in first and we're going to put this flange in there and now we've got some big old screws that go in there this is one of the reasons I bought the JIS screwdriver get these started and the way these are designed is you just run these down and the washer in there that crush washer will squish and then these are designed to bottom out on the head that way you know you've got the same amount of crush on each one so we'll just tighten these equally I'm going to get on these now with the Philips bit in a socket and get a nice feel for how tight they are a little more than the screwdriver it feels pretty good you'll want to go too tight and just for good measure we'll give them one whack with the impact okay definitely don't want to strip those that would suck time to get the pipes on this one's number one they actually label them for you with a little sticker number one and we're going to put one of these on first it's going to go just like this and then we can go ahead and push it on there I get the flange in there first there we go I'm just going to leave it like that for now and get the rest of the pipes put in place so when these go on you got to make sure that you put the proper heatsink and clamp on there's a bolt facing out like this there's the other set are the other way so there's a bolt facing in the other direction that way you can get on the pipe I had this wrong the first time ah hello now I get to put the collector on let's find number one pipe number one pipe is right there these are all labeled one two three four so let's see that's one and that's pipe number one this is going to get a little tricky so I get them lined up right this let's just play around with these until they all start to line up and send some ones up okay that's four okay there's one and three and get four started one in there come on it's a little tricky because they have to be in just the right position okay there's one and two three let's get four and then it's just going to be a lot of wiggling until it goes all the way and there's Springs that hold these the collector and pipes together I'm just going to keep wiggling until I get them all the way on there all right we got things together here now we can get the springs on that hold the collector and pipes together and they even give you a little tool to pull the spring in place with let's see how that works not too bad really we just do the same thing over here on the other side and the collectors on all right back to the front now make sure that the pipes are all the way on to that plan you give them a little tap with a 2x4 not going to hurt anything and get that up there nice and tight and get those as straight as I can once all the way up and we'll do the other side now we can get the silencer mounted to the collector on the back here is a bracket this goes on there and it goes like that with that part pointing down there's a rubber bumper that'll go on there later for the center stand to hit against and these bolts go in here and hold this bracket to the silencer just get those started finger tight for now okay so we're going to push this on until it lines up back here and it's going to mount right here it will mount right on the rear foot peg area and I don't have any any instructions with this particular one they kind of give you a generic one I'm betting there's some on line but for right now what I'm going to do is just hang this here tighten this up and just run a bolt through here to hold it in place temporarily got a temporary bolt put through here this is all just for test purposes so I just fire it up make sure everything's okay and then I'll go back and do all this correctly later okay that's tighten that bracket and then we'll tighten that bolt up ok one more thing get up the clamp at the collector we've got an exhaust system hey Seamus how about a quick walk around see what we got here damn looks nice good looking exhaust bolts on fairly easily sweet hey we're just about ready I've got the ignition wired up to the coils then right here I've got my 12-foot supply that runs up to the oil pressure light that wire runs down to the oil pressure switch twelve volts is hooked up to it right now and the light is on the oil pressure lights on I got this little bottle sitting here that I used before on the saber for my fuel supply probably just rigged that up right here on a tripod or something to let it feed kind of like an IV and this is the starter wire so when I bump it against the 12 volts it's going to crank over I guess that's about it I just got to get oil into the tank and engine now and I've got some here I'm going to put some Rotella tea in there some 1540 Rotella tea has ink in it good for these old engines so let's get the oil in there and then Wow exciting moment we're going to fire this baby up all right we are we're ready to fire this thing up I put the tank on I wasn't going to do that because it was kind of cruddy inside there was a little bit of yucky gas in there but I decided to go ahead and do it because it's a lot easier to deal with probably a little bit safer than you know some other little bottle nearby that could fall over and catch up fire speaking of fire because this is the first time firing this up things should go okay but just in case they don't good idea to have a fire extinguisher nearby so I've got things wired up as I mentioned before I got my little teens battery pack there it's been charging for a while and it's probably up good enough now it's going to be powering up the ignition just that little battery so they want to run it too long but it should be enough to fire it up and just make sure everything runs okay maybe run it through some gears real quick and then shut it down I'm not going to run it too long and then once I do all that I can readjust the timing chain later but here we go okay here we go all this time and effort into this thing be really awesome if it fires right up so let's turn this gas on to the on I've already done that and filled up the float bowls so everything should be good there I'm going to put the choke on get a connect my 12 volt supply here so I can I can kill the power just by disconnecting this from this yellow wire I've got a oil light and that's our crankin chokes on this is going to be a little tricky because I don't have to do this and hold its rod at the same time they hope it's pretty cold too you know so what this battery's going to be enough to kick it over let's find out what happens here we go cold-blood good enough for me haha these little tuning but it's running and all the gears work okay yeah well who'd have thought that on this cold ass winter day would be the day that I fire this thing up and get it running for the first time there's snow all over the place out here and well I'm glad it runs it runs pretty pretty fine in fact just got to do a little tuning on it but now that I know that I can continue with the project get the wiring harness on get the alternator hooked up because we were just running off from a little battery there so not really sure how much power it had for the coils and all that stuff but it was running on all four cylinders and it sounded really good and no weird noises went through all the gears okay I am very pleased as I'm sure you are some people wanted me to run it without the muffler on but I'm not going to do that I don't like loud bikes if you like loud bikes and that's your thing that's cool but not going to happen with this bike I'm going to keep the baffle on there so Wow came a long ways to get to this point and I'm really glad everything went okay it pays off to be meticulous about everything and make sure it's alright so there you go all right well thanks for watching thanks for all the donations a lot of them really helped out with making it get to this point so thank you very much and don't forget to subscribe share and until next time twork on these six millimeters
