hello my friends! after perusing the KV i've discovered some, but not enough info on this subject. i just popped my third belt and @ $180 per and nightmare install i've decided to switch to a chain. so far the info i've collected(with help from one of the nice people over at crossroads)i believe i heard something to the extent of: 130 length chain to start out with (too long just in case, cut to fit) a 24 tooth 1/4" offset front sprocket from a 91-92 sporty?(i think that's right). a 51 tooth back sprocket bored out to fit buell rim? does this sound ok? please elaborate and clarify if you're in the know, after maybe i can ask blake to move this to the KV. any and all input will be greatly appreciated!!

Sounds Good Tripp,

I can't remember what sized sprocket I used on the front but I did purchase the 530 Chain of 130 links and cut to shorten it. The rear sprocket is from a early 80's Big Twin bored out to fit the wheel and I did use 51 teeth, the front sprocket was indeed off a 1991 Sportster. There was also a spacer I needed and found the part in the KV.

Just remember that the nut on the end of the output shaft is reverse thread!!!!!! Others on the board have made this mistake and has caused much upset.

I am now 20,000km of trouble free chain driving, I also use the Bel Ray Chain Lube that is a wax and does not fly off. Not too messy in the end but I can no longer worry about throwing a belt.

Tripp,

If your using a late model aluminum swingarm, you will need to go with a very large front sprocket. Even with a steel swing arm, you will have an interference issue with the swingarm mount block. You can either machine it yourself or let it self machine. I run 22 or 21 fronts and 44-46 tooth rear. I'm not sure what you are refering to by machining the rear sprocket. Sprocket specialist sprockets are a direct blot on, all you have to do is file down one side of the sprocket bolt washers.

If you really want to go nuts, you can install an XB12 (1.5 ratio) or XB9 (1.676 ratio) compensated clutch basket/primary. extends both primary and final drive chain life and is easier on the rear wheel casting running a chain drive conversion. You need to do a touch of clearance machining on the derby cover bolt bosses on the primary cover to make it fit.

thanks for the info guys! i do indeed have the aluminum swingarm, i'm thinking of using my old primary tensioner boot(if i did'nt throw it out) as a chain guide for the swingarm, now if i can only figure out how to attach it!! we'll see, i'm going to check out sprocket spec as i would prefer not to machine the rear sprocket, another thing is what is the most aggressive set up without getting too ridiculous small front sprocket and big back one another words will a 51 tooth back have more pull than a 44-46? might as well get the most i can out of the sprocket arrangement!! thank you very much for the input guys, much appreciated!!!

Spidey that was the old shit I was using compared to the newer chain wax.

The newer stuff don't fly off.

Geeeesh
