Suu Kyi Posted June 28, 2022 Share Posted June 28, 2022 Looked through some old posts on chain adjustment but couldn't find an answer to my particular question, hence why I'm starting a new post on this common subject. The manual states that to adjust the chain tension the axel and adjuster nuts should be loosened whilst the bike is on the side stand. Then raise the bike onto the centre stand, adjust and align aiming for a slack between 35mm to 45mm, then place the bike down onto the side stand and tighten the axel and adjusters. Why would you need to loosen and tighten on the side stand and adjust on the centre stand? I've always loosened, adjusted and finally tightened all on the centre stand, then off onto the side stand for a final check. Your thoughts and practices will be appreciated please.

Bimbim18 Posted June 28, 2022 Share Posted June 28, 2022 I think it has something to do with the dynamic nature of the suspension. Is probably more accurate with some weight on the tires. I've always done mine on the center stand though. 2 Link to comment Share on other sites More sharing options...
Supporting Member dazzler24 Posted June 28, 2022 Supporting Member Share Posted June 28, 2022 Same method for me as bimbim18. On the center stand and then use a rag between the chain and rear sprocket to ensure that there is tension on the axle against the adjusters before finally tightening the rear axle nut.

peteinpa Posted June 28, 2022 Share Posted June 28, 2022 Unless your suspension is so loose that the rear sags on the sidestand there is no difference. Link to comment Share on other sites More sharing options...
KrustyKush Posted June 28, 2022 Share Posted June 28, 2022 Hmmm, I never considered it had anything to do with suspension. I’ve never heard of this method before this bike. I assumed it had to do with safety. Maybe a likelihood of bike being pushed off center stand while wrenching on the axle nut. Most bikes nowadays whether belt or chain, have no center stand so there is no such risk. All expect measurement to be done with full weight on wheels. It is only the position of bike while loosening/tightening the axle nut that differs. Link to comment Share on other sites More sharing options...
OldBikers Posted June 28, 2022 Share Posted June 28, 2022 Could it be that it's safer to loosen the axle nut while the wheel is on the ground rather than the bike falling off the center stand. Link to comment Share on other sites More sharing options...

I know it can happen but over 65nyrs of owing XX bikes not 1 has fallen off the centerstand. IMO, you gotta be a real dufus for that to happen. 4 3 Link to comment Share on other sites More sharing options...

Suu Kyi Posted June 29, 2022 Author Share Posted June 29, 2022 Thanks for your comments and yes it seems loosening and tightening on the side stand is to prevent the bike being shoved off the centre stand due to the high axel torque setting, hence I now torque it up to no more then 80 ft lbs. I also adjust the chain slack to around 40mm. The manual says 35 to 45mm. Link to comment Share on other sites More sharing options...

KrustyKush Posted June 30, 2022 Share Posted June 30, 2022 Similar to Harley beginning every maintenance procedure, no matter how simple, with “Remove main fuse” to prevent any possibility of an inadvertent starter motor activation or other electrical event. Not too many ppl actually do this. Link to comment Share on other sites More sharing options...

Manxkiwi Posted June 30, 2022 Share Posted June 30, 2022 I have always tightened the axle nut with the bike on its wheels (any bike). There is a small amount of play within the axle, swingarm and adjusters. All the play is taken up in the natural direction if you do it this way. I also hold the bike somewhere and push my knee onto the the rear tyre as I tighten the nut, to make sure the adjuster blocks are 'home' and any play (fore'n'aft) is also taken up. You could argue that it makes very little difference, but as an engineer, I have always done it that way.. YMMV. Link to comment Share on other sites More sharing options...
peteinpa Posted July 1, 2022 Share Posted July 1, 2022 To remove that play while on the center stand put bike in gear and rotate tire to pull chain tight. My way, place round shank screw driver in bottom, rear sprocket/chain interface,roll tire forward till tight. Link to comment Share on other sites More sharing options...
