Missing chain roller
Permalink  
 


Are these vital? Where I think the chain roller should be... there just seems to be a stub of snapped off bracket.. so no option now of running one. Any disastrous effects?

The top chain roller is there to take up lose chain
when the suspension is/near fully compressed..
So theres not really any issue not having it unless
yer into jumps...

I don't have the top one as the rubber fell off the bearing.

Mr Yamaha's bean counters tend not to let the designers put anything on a bike that isn't useful.

The upper chain roller is even more important if you have lowered your TTR - or are a heavy lump like me disbelief

The fact that yours has been broken off indicates some heavy chain/roller contact!

Oooo err.. Worrying. It does have a lowered linkage, but i have the original i need to put back on, because i am no midget... I'm not into jumps, but i dont really have the option to put one back on, as the lug is missing off the frame, and i'm no welder :(

Along the same lines, whats the recommended chain slack? The manual says 35-50mm so i've adjusted for about that, but it seems a bit hard to judge, as if i pull the chain up 50mm is hits the chain slider.

Replaced the chain yesterday (courtesy on Mr TTRfan) for a renthal, as the chain on it was slacker than a slack thing... could virtually pull it off the back! And could be heard slapping about. Also found it was a non-oring chain when i broke it apart.

The fixing lug for the chain roller is basically just a bit of tube. 

I think you will find you need to adjust the chain on the tighter side of the spec. when a lowering link is fitted.
