Yamaha TRX850 Enthusiasts Forum

can anyone please help me, what are the standard settings for the front forks and how do i make adjustments. i have just had the forks out to replace the oil and do a bit of polishing and it now appears to have no rebound dampimg at all, help please

That`s because there is NO rebound adjustment, just compression damping.

Sorry to correct you Mincehead.

The front for has only rebound damping, and only 4 positions of it.

The TRX fork rebound damping is a very crud system. That is a disk wit 4 different size holes that is turned by the big D shaped needle that is attasched to the fork cap adjuster .
If this D needle is both fed in to the dapper part witch has a same D shaped hole the gaming might not be adjustable.
Also if the oil is to thin (low grade) than do gaming can be felt.

On the bleu paper
Upper part is a R6 cartridge damping system+R6 fork-cap.

The lower parts are standard TRX.
-Bumpstop-Rebound damping tube-Adjusterneedle on fork-cap.
-Chrome tube or inner forkleg.



For the setting
I used (from memory ) SAE 15 oil with an air chamber of 140mm.
Setting 3 on rebound. as the system has no real end it goes turning clockwise 1,2,3,4--1,2,3,4-- (there is a big gap between 1 and 4).

B-art

Damn you`re right of course , and yes it`s a pretty naff standard set up but can be improved a great deal with emulators I
believe.
