Drive chain adjustment query

Hi all,


On inspecting the the rear chain adjustment on the bike, ive noticed that my chain lies in its rest position above the lower chain guard, roughly 5mm above the lower guard with the bike sitting on the rear stand. The chain has roughly 8mm of play. This issue makes me unable to follow the manuals guide of centre line of chain rivets to bottom edge of lower chain guard to equal 6mm. if I tried to do adopt that method at present the chain would ofcourse become way to slack and impossible to achieve anyways.


Makes me question wether the lower chain guard may scoop lower down than standard for some reason for example an after market replacement. Has anyone else encountered this problem?. I like to verge on the side of caution with the chain adjustment and it currently has 8mm of play which im happy with but it is not sitting in correlation to where the manual says.


Many thanks Jimmy

Will get a better pic on the rear stand to show position of the chain to the lower chainguard asap but if you zoom in a little you may see that it rests behind the cover not under it

If the chain has the proper amount of play then dont be concerned. Ride the bike

Hi George, im riding it as much as I can before winter . Im not that concerned I just wondered why the chain isn't resting at the normal place. I restore classic motorcycles for a living and have endless fault finding problems, I like to get to the bottom of things

Normal place being as you see in the manual diagram which you have posted, my chain resting place is hidden behind the lower guard. Just wondering whats off to make this happen unless im missing something?

Cheers

When you measure chain play, you set the top of the chain taught above the swingarm. Then you pull down on the chain below the measuring point to see free play.

You repeat this at several locations along the chain.

If when you pull down on the center of the chain below the measuring point you are around 6-8 mm, then all is well.

The other thing to ensure is that the rear axle is below the centerpoint of the rear hub. If it is not, then someone screwed up and your cahin will ride high compared to the lower chain guard.
