Forkbration

Hey Everybody,

I'm still very new to this forum....actually i've never posted....

Anyways, i have a 2005 919 completly stock except for a fender eliminator. my next purchase is some new mirrors ( i hate those mickey mouse ears) and a power commander.

I have a problem. At about 160km my front forks seem to vibrate. not up and down ike they should. but like....front to back. I dont know how to explain it and at about 180 to 200 i feel in the handle bars pretty bad. Do to just need to adjust the forks. or maybe there's an inperfection in the tire. but its band new. they are michelin 2 cts.

if anyone could help me out. i would really appreciate it

Thank you very much

I can't really help with your problem but I can be the Welcome Wagon!

Now, let's see, 160km X .6= whatever American.

Did you have this "forkbration" prior to the installation of the PP 2CT?

Did you follow the installation procedure for the front wheel.

Heads-up... Check your new 2CT for a possible recall. Read all about it here.

These Michelin's have no balance mark, they still require balancing.

I would suspect the same thing, especially since it's vibrating back and forth. Perhaps something is a little loose.

Vibration

Whatever, please don't do 120mph again till you get it fixed. Head shake is next and pushing daisies is last.

i believe it was doing it before the 2 ct.

I didn't do the, "put the wheel on the ground and pump the shocks". I know i torqued them up pretty good. but i dont have a torque wrench.

I should maybe right installing it again

thank you for your help

Do you know how to check the steering head bearings for looseness? It has nothing to do with the top nut being loose.

Try jacking up the front end and grabbing the fork to feel for play -Grab the lower legs and push/pull forward and back. The bike should be supported under the engine, if you have a center stand just get the weight off the front end.

BTW: You can multi quote a reply. Use the " symbol to the right of the quote icon.

I'm betting my money on the tires. Try some Metzler M3 tires. I don't think you will be disappointed.
