wobble'e quad - 400ex

[hks308]

i just bought a 02 400ex today and it runs great, but when i hit middle of forth and fifth gear, the quads front wheels start whobblin and shakin. the rims are bent a little if that has to do anything with it. any advice to tighten anything???


thanks in advance...

It's prolly just yours rims. Might want to check your bearings though.

I bet its the rims also. it doesent take much. or if there is mud on them that will make the front end shake BAD.


I had mud caked in just one side of my beadlocks one time. OMG, the front tires where hopping off the ground.

don't think it is becuase they are dirty. cuz it was wobblin when my quad was clean.

Checkyour wheel bearings, a-arm bushings, and ball joints. My rims on my banshee were bent pretty bad and it didn't shake at all.

could just be SLIME in the tires ....... mine did that when i had slime in my tires

I guess it's normal, mine does it too and my rim isn't bent and its all tightened.

my buddy said it could be the slim. im thinking about draining out the air and seeing if there is slim in there. but when im going that fast, its hard to control it..

I'd bet it's SLIME or some other stuff inside the tires. Removal and a good cleaning will be required.

I have seen worn out shocks do a similar thing in that they will bounce like a basketball going down the road and it's really compounded at speeds like you describe.

To check your bearings, take the weight off the front and see if there's any slack by trying to move the wheel from side to side. They should be nice and tight.

Slime is the worst thing for anyone going over 3rd gear. I had slime in fronts and rears for 1 ride and it was like riding a mechanical bull, that crap is worthless. Went right back to camp, popped the beads and drained it out. Go with tire balls if you are worried about flats.

I corrected that on my quad by adjusting my toe in to manf specs.

(you do that by loosening the tie rods, and adjusting in / out. )

i had the same problem wigle ur handle bars see if there is any play. if so you probally need tie rod ends.
