Millyard - Honda SS100 and SS180 V Twins

in this video I'm going to be talking about my Honda SS 100 v-twins and my SS 180 v-twin we'll have a quick look inside one of the engines and here a few run I built my first Honda SS 100 engine at a motorcycle show in 1999 and when the bike was finished I rode it around for several years before selling it to the barber Museum in Berlin Alabama where it's currently on display alongside my Kawasaki v12 v8 this is my 2nd SS $100 made in 2012 to replace the one that I sold to the barber museum my 2nd SS 100 is very slightly different to the first it has a silver painted headlight rather than chrome and no indicators and slightly bigger seat hub with a big 12 volt battery the carburetors have Bell mouths rather than K&N filters the rear wheel has stainless steel polished spokes a new chrome which is a lot better than the wheel that came with when I bought the donor bike the rear sprocket has only 32 teeth to up the gear ratio for the v-twin engine the left hand switch gears been removed my world is locked the slot and polish to dance smooth and the right hand switch gear is standard with the on low and high for the headlight when it made the megaphone exhaust system I touch it in tight and place to the frame here's my third ssj100 part next to my second this one has a polished aluminium seat hump that I made from one sheet of metal I was very proud of that other than these differences the third SS 100 is pretty much the same as the second SS 100 so let's have a look inside the engine I'd recently had a slight problem with my gearbox it was clicking in 4th so I thought let's take it out strip it all down find out what's wrong with the engine out and stripped this is what I found the 4th gears both had a tooth missing so with the faulty gears replaced and everything clean I can start putting the engine back together this is the crankshaft which is made from standard SS 50 crankshaft parts that's the first thing to go back in with the crankshaft in I checked it rotates and it spins free because the ssj100 engines got a vertical split crank case I always use a bit of Permatex ultra gray sealant on the joint along with a gasket I showed how I made my gaskets in a previous video so you can see how it's done there with a thin dismay of gasket sealant applied I place the gasket on this goes on in two pieces and is pressed down a thin smear of ultra grade then applied to the right hand current case joint now I can install the right hand crank case lowering it carefully over the crankshaft and gearbox main shafts and pressing down onto the dowels I always check the crankshaft rotates and the gearbox rotates in the on this kangan you have to do up a little selector drum screw first to hold the selector drum in the correct place and then you can check your gears by rotating the selected run and getting first second third fourth and neutral which it does lovely next I installed the gear change shaft and select a mechanism and engaged it with a selector drum now I just checked it moves to make sure it's not caught the next thing I'll be pitting is the clutch and primary drive cog well the primary drive always goes on first followed by the clutch the clutch incorporates a centrifugal oil filter in these four galleries and sometimes get a bit gets a buildup of crud in this case it was clean I then fit the tab washer the spring-loaded Belleview washer and the castle nut which spins down freely by finger then using a special castle socket on my ratchet I tighten the class one that with the castle nut type I bend up the tab washer with a screwdriver then replace the clutch cover and it's four screws I then fit a new outer clutch cover gasket and the clutch cover by securing all the screws tight with the bottom and complete it's time to fit the rear piston so I place it down over the connecting rod pressing the gudgeon pin and fit the circlip then fit the rear barrel making sure the piston is set at top dead center the one-piece cam chain is then threaded through the rear cam tunnel around the crankshaft and out through the front cam tunnel I then fit the rear cam chain idler and rear cam sprocket with a little Oh mark pointing towards the top gently lower the cylinder head down and engage the sprocket onto the camshaft and place in three screws and tighten then replace the rear rocker cover followed by the four and six nuts and tighten next on is the front barrel and piston feeding the cam chain up through the cam tunnel as I go I then replace the front cylinder head in the same way as I did for the rear with both turned heads fitted I temporarily fit the flywheel to check the cam timing to do this I line up top rear with a mark on the engine like that and the zero on the cam sprocket needs to be in line with the dent at the top of the cylinder head then I repeat the same for the front and they're both perfect I'm well pleased with that the last thing to do is to fit the two side clubbers to the cylinder heads these are hard on the two Phillips screws and a long bolt that goes right through the center of the cam shaft and screws into a cover on the opposite side of the cylinder head with the engine back together let's go outside and hear them run some original recordings from 2011 others were done just the other day [Applause] [Music] [Applause] [Music] [Applause] to make the SS 180 I use the engine of my Honda c90 a 1974 six volt version I converted the clutch from automatic to manual and fitted the four-speed gearbox from the Honda s 90 the crankcase modifications were quite straightforward I couldn't make the V angle 90 degrees because I needed to make sure the frame was strong enough for the extra power this bike would do 80 miles an hour the SS 180 has a totally different sounds the SS 100 's and is very free revving thanks for watching this video I had great fun making here please hit the subscribe button see that missing in my future
