Putting Kawi wheels on my XS650. Strangely everything seems to fit. Only problem seems to be that the Kawi rear drive sprocket is larger, so the XS chain is too short. How do I know what size chain to get for it?

slide the wheel all the way forward then put the xs chain on top and bottom of the larger sprocket and count the missing links...you realize this is going to low gear your bike?

I imagine there are a lot of wheels that will fit. When I got my '73 TX, there was a Suzuki wheel of some sort on the rear - unknown to me. Didn't realize it until time came to upgrade the swing arm, shocks, brakes, etc. What a mess.................but I was able to find an original replacement wheel.............. The Suzuki wheel worked just fine though. But as long as I was freshening things, I decided to return it to original - steel wheel with spokes. Looks much better now. Next step is to relace with stainless steel spokes.................Wes

104 links is the usual stock size. Aftermarket chains are usually sold in 10 link jumps (100, 110, 120, etc.). A 110 should probably do but best to measure as Jayel said. How big is the sprocket (# of teeth)? If it's in the 40s, you're probably going to need to change it. That would gear the bike way low.
Most of the bikes I've had fall between that 100 and 110 link size so I get 110 link chains and shorten them to the length I need.

Not sure what you mean by "count the missing links" Could you explain, please? Yes, I figure this will change the gearing. If I'm understanding how it works, it will increase torque in lower gears, but will have to turn a higher rpm to maintain the same speed in the upper gears.

Yes, a 40 some tooth rear sprocket combined with a 17 tooth front is gonna scream up to about 75 before it blows up. Great for in town cruising/racing. I have a 36 tooth back and believe me, it's plenty for the street. Most of the guys here think I'm nuts for not going with a 32, 31, or 30 tooth....naw, rather have the "right now" torque.
He means check out how many links you are missing by counting the empty spots on the sprocket.

yes count the missing links between the ends of the chain then add 2 you will want to have some slack in the new chain for adjustment

Thanks, I think I got it. Hope so. And, since I'm remaking the bike into more of a racer than a cruiser, I like the idea of more torque off the line, so I think the larger sprocket is the way to go.
