Problem with front Wheel; need some help

Sounds like it's out of balance.

Hello again motokid,

No, I had the dealer computer spin balance it after I mounted it. I also checked the balance when it was on the truing stand. Beside if it was out of balance wouldn't the pogo action increase as speed increased. This just showing up in that 30-40mph range for the most part.

Ahhh...you kinda left that small detail out of your original post.

Spin the wheel/tire and look for "out of roundness".

I'm guessing you got a bad tire.


I've never bought Kenda tires.....was there any kind of warranty with it?

Can't remember where I bought it. Motorcycle superstore; Revzilla; or Rocky Mountain MC. but it was 4-5months ago. I had originally wanted to change out my worn Trailwing last summer but decided to wait a little longer till it got more mileage (about 5800) before changing out in Dec. well I'll just use it up around here trail riding and next summer I'll change it out for my trip up north with my other set of wheels (Warp 9) I have my offroad non DOT tires on.

ps. Is there anyway to check for out of roundness before mounting the bad tire?
pss. I just located the sale history. I bought it at Rocky Mountain MC so I might be able to return it but I would have to unmount it, package it, and pay shipping for a $46.00 tire. So I think I'll just grin and bear it. Its replacement has already arrived ( Shinko E700 front and 705 rear)

Tie a string tightly between the forks and just over the tire. Spin tire and see if the gap between the string changes dramatically.


As for checking "roundness" before mounting?

I don't think so.

And "out-of-roundness" might not be your problem. I'm just guessing here.

Im surprised you didnt notice whether or not it was out of round while balancing it.
The kenda 270s I had on my KLR were a tiny it out of round, they stopped shaking once they wore a touch.

TNX motokid I'll try that.

I don't know why. Maybe because the spin balancer operates on weight only and out of round is a physical deformation which may/may not be in the area of where the balancer told us to put the counterweight. I'll have to check when I try the string check idea from motokid.

I had a Qlink XF200 that did the same thing, and the front wheel was out of round. It would balance fine, but a combination of the rim being out of round and the tire made it hop.

I raised the front off the ground and put a wood block under the wheel so it was very close to, but not touching, the rim. Slowly spin the front wheel and observe the gap between the block and the wheel. I had to tighten some spokes to get it back in round, but I would tighten a few, spin it again. Tighten a few more, spin it again. It took a while, but eventually I got the wheel round and the annoying hop went away.

I guess what I am saying is make sure it is not just your tire, and verify that the rim is also true and round.

D'oh...

Forgot about spokes. Check those.
