yz426 suspension advice

[laserracer]

ok after riding my sons yz 250 2 stroke in tight single track ive come to the conclusion that my yz426 is pushing into the corners.. ok the real reason i cant catch him is the 426 is big and heavy and the rider old and slow :(....anyways i think somwhere on the net i seen that either raising or lowering the front forks in the triple clamps will help fix this ..anyone know? do i raise them or lower them and by how much

Sounds like it might be soft in the front end to me, but I'm no expert. Barty5 had a 426 maybe he could let you know.

Do you have the right weight springs in yours?

springs are close ...is setup for 95 kg im 100kg yeah yeah i hear you... lose weight and i'll corner better.. but what can i say.. ive got a pie fetish :yes::woohoo:

thtas about what mine was set at was around 3 clicks soft of center and standard on rebound handle fine for me.

OK seems to handle in the ordinary stuff, but when it gets tight it definately wants to push to the outside of the corner ,but not every corner, sort of a vague feeling as if you never know what its going to do next, my son hopped off his 250 and rode mine and noticed it straight away
and when i rode his 250 it was like it was on rails

Danger will answer your question there mate. if I remember what i read,raising the forks in the triple clamps will lower the front end making the bike turn sharper but will reduce high-speed stability. I suppose its all dependent on your sag settings as well. I stopped eating pies and I went from 100kg to 78kg lol. 22kgs make a big difference on a tight corner:doctor:

Thanx buddy... yeah ive told wifey and the doctor im only eating diet pies from now on :laugh:wife slapped me around the ear and my doctor said if he hears im still eating pies hes gonna stick his fees up $10:shit::laugh:
i also told them its not the pies that put on the weight ...its swallowing...maybe i can just suck them:laugh:

If its pushing to the outside in corners slow the forks rebound damping would be the first step. The front tire could be rebounding too quick causing it to push to the outside.
The opposite would be if it tucks to the inside of corners speed the rebound damping up, in effect pushing the front tire into the ground to hold the front up more.
There are other issues that could cause this but without looking at the entire setup thats the first thing to try.
Other possibilities other than a four stroke being more top heavy than a two stroke and pushing in sand or a bad front tire are that you could have too much trail, you could try raising the forks in the clamps no more than 10mm above the triple clamp.
Too much fork preload, spring rate too high (but you say this is ok) too much low speed compression damping, the rear riding too low, air pump (bleed forks), anything that makes the rear lower than the front, or sticky forks and there are lots of reasons for that problem.
Try the easy adjustments first.

Thanks DANGER thats what i needed to know:niceone:
