I have an 05 KFX400 and need some information regarding rear suspension adjustment. I'm a small guy (around 140lbs) and would like to know what I can do to soften the rear suspension. My friends ride Z400 and have no problem pulling up the front end in 1st, 2nd, 3rd, and even 4th gear. I struggle to get mine up in even 2nd and 3rd, I really have to jump down on the back of the quad to get it to pull up. Seems like my weight may be an issue as there isnt enough weight on the back to pull it up easily. How can I go about adjusting the suspension in the rear to compensate for my light weight. Thanks in advance!

Take a straight head screwdriver and adjust the screw towards the S, but only a 1/2 turn at a time and try that out...

 

wow, fast reply! I'm going out to take a look at it right now. Thanks!

Its just the small screw in the middle, not the entire ring, correct? I turned it about a half a turn, gunna go out and test ride it, Not really sure if I'll be able to tell the difference as we have quite a bit of snow here, still got some kold kutters in there, but ill give it a whirl. Thanks!

 

YES, just the little screw. I think it is a goldish color. For your weight you might want to turn it another 1 1/2 turns...

I can't keep mine down

 

I got the 06 and I can catwalk it in any gear. Just gotta get the revs up a bit in 4 and 5. All stock. And I don't need to pull up that much.

 

seems to be the problem is traction, my kold kutters are warn from street riding. I rode my buddies DVX400 with fresh screws, had no problem pulling it up. Thanks for all the help.
