Another chain tension thread

[GlenR]

Hey hey, Have been banging my head against a wall over this one, but how do you get the chain tension set on an NC35? The other threads on this forum are rather inconclusive.

The bike has a +2 rear sprocket and even then you cant get 25mm slack total (up and down) before hitting the swingarm. The hub is installed correctly with the shaft at the lowest point.

How is everyone else doing it? At the moment I'm just doing it by trial and error till it feels alright but by god what a pain in the butt that is!

Was thinking maybe its possible to set it how I like by trial n error then measure the max vertical deflection of the top chain run and use that to set the chain consistantly. Ideas?

Cheers!

As I recall, hitting the underside is no big deal as there is a hard plastic chain guide there. When I used to do it on the race 30, I would push the chain up until it hit the guide, then measure maximum drop to set chain tension. In fact, looking at the parts fiche, the chain guide's official name is "chain slider" which suggests it is for the chain to slide over due to a preplanned degree of slackness. This works top and bottom.

Your best to check the tension with somebody sat on the bike with the suspension compressed, gives you a better idea of what its like when your riding it than trying to guess, you can check it on your own if you lean across the seat and reach over.
