Title: Couple of stupid questions about chain adjustment
Post by: EEL on September 27, 2010, 09:02:42 AM
I've done this adjustment several times and I never really though about it until yesterday.

1) If you raise your ride height on your bike, that that impact how you tension your chain? Doest the required play change?

2) Does adding teeth to the rear sprocket change the play needed to properly adjust chain tension? This doesnt really apply to me as I only added 1 tooth in the back and there's no significant difference but I was just curious.

Thanks in advance..

FYI. I have an 05 S2R 800

Ride height does affect the amount of slack you need. Increased height will require more slack.

Gearing does not affect it..

Ok so how much more slop? it doesnt say on the bike owner's manual or shop manual what to do.

I got to the point where I could feel when it was properly tensioned. Driveline lash on/off the throttle and it's too loose, binding upshifts and downshifts and difficulty finding neutral meant it was too tight. Usually though after finding this sweet spot and measuring the slack at the centerline of the rivet in the link mid-chain it ended up being around 31mm.

The way to determine the exact amount is fairly involved.

You'd need to move the swing arm to exactly level (longest chain run) which would require removing the shock. Adjust the chain at that point so there is a small amount of slack.

Replace the shock and measure the slack and use that number.

I raised the height on my DSS bike and added 5mm to the slack and it worked for me.

Get a couple of "fat bastid" friends to put their weight on it til it's level (centre of front sprocket to centre of back sprocket, use a spirit level and string line if you want) and/or remove seat and use a ratchet strap around frame to swing arm to pull the swing am up.
Bit hard to do on your own on a sidestand but possible, easier to do on a proper rear stand. When you get it level, adjust for a little bit of freeplay, 1/4 inch or so up and down. Main problem I had with raising rear ride height is chain rub on the front rubbing block.
