    hello all I have just assembled my engine and the chain is rubbing on the clutch housing, I searched and could not find anything about this on the forum. I have attached a pic so you can see what is happening. of coarse any help much appreciated.

    One of my engines did the same thing. It has one of the wider output sprockets on the engine and it took a while for the sprocket to break in so the chain would sit on the sprocket all the way. I just took a dremel tool and ground some clearance into the cover. It doesn't take much.

    thanks for the reply, I will cut down the housing a bit, thought I would check with some more experienced guys first. I didn't like the rear sprocket that came with the kit, it was just a flat pressed out plate so I had to redish the wheel and pack out the axle, this worked to my advantage because I had choosen a 700c hybrid so it gave me more clearence on the stays np. worst thing i guess is the sprocket had no lead on it so no doubt it would have jumped a tooth some time. anyway the grinder made a nice lead while the wheel was spinning. should be up and running soon

    Next Problem

    Anyway, whenever I turn the the output shaft there is a grinding noise, I just figured the clutch needed to bed in or something. haha lol:lol:. So I have pretty much everything done (did a few mods on the bike too), I pull off the gear reduction\clutch housing to check for lube status- well there wasn't any and some swrew that holds the clutch adjustment from spinning is making a nice big groove in the housing. No problem I get the thickest gasket paper I have and decide to add another one to the 2 that are already there, whoops not enough! I decided to do the moral thing and make a spacer from some alloy plate I had laying around. of coarse I mark out to the housing instead of the gasket; wrong, housing is cast freehand gasket is actually right, almost come to grief. All finished now ready for some fuel.

    Night before last I dreamt I was riding on it and my fuel tank mounts came loose and it slipped down the top tube, when I checked it I had never put fuel in it, it was just running on a bit left in the fuel bowl.:grin:

    hope it is this efficient!

    anyway tomorrow I'll hopefully fire her up (yes she's a girl lol, wouldn't have so much trouble otherwise?) Just kidding
