Hello

Any thoughts on my 06' Uly that has a mild 'pulse' or wobble/vibe when going into a corner with giving some gas.

Right seems more than left cornering and giving the rear wheel power makes it happen.

It is not noted with clutch pulled in. And I think it is coming from the rear wheel ... front is fine.

Thanks for your opinions: )

Chas

Maybe check your tires. Irregular wear (squared off, or cupped) or the wrong pressure can cause wobble or vibration in corners. Just a thought.

Sounds like a case of the Dunflops for both you guys. Throwing the Scorpion Syncs on is the best mod you can do to the bike.

Chas- check your rear wheel bearings; it could be related.

Hughlysses, me too: (

The tires look worn, but uniform. The wheel weights are still there and no dents to the rim. Dunflops are flops with front wheel feeling fishy.

The right rear bearing 2-3 wks ago had a goober of lube pushed past the seal. But with only 2.5K miles ... even 20K miles, I never seen this with a bearing.

With everyones help most likely pull the rear wheel and change out the bearings. Also ordered Syn's will be coming soon: ))

Thanks

Chas

Barker,

You still have the stock brake pads? Have you re-torqued the steering head? These are likely to cause your problem.

You got the procedures for the pads? Clean the pistons with a rag or something before you push them back in and wipe the rotor down with brake cleaner(careful, it eats powdercoat finishes). All of that stuff is in the knowledge vault, including break in procedures. The head bearing info is in the service manual.
