hey guys im new to the forum and i need some hel with a bike i recently purchased. its an 02 f4i unsure of miles was told cluster has been changed. anyways the problem is a vibration that starts at 4500 rpm. either drivin or sittin still just revving. doesnt matter which gear or speed. ive read alot about the cct and i have one ordered just unsure if it causes that kind of vibration. i have checked all bolts and everything seems tight. the bike has a stunt cage but ive ridden other bikes with them and the vibration wasnt there. could the valves need adjusting or what ? any help is appreciated.

 

It does it when its sitting there and I rev it.

 

mine has the same issue. would love to hear what everyone says. it doesnt hinder performance though

 

The cctl only makes a buzzing noise. It's not related to and cannot cause any vibrations unless it's totally shot and not applying any tension to the cam chain. (destroyed valvetrain is the result)

The mileage is stored in the cluster, not the ECU. so changing the cluster WILL show different milage.

Some have said that stunt cages can actually cause vibrations because of the added weight hanging off the frame/motor allowing for resonance... The cage also means that most likely there is a history of abuse with the bike. Is the cage pretty rashed up? Have you tired removing it to see if the vibes are still there?

That said, ALL bikes vibrate a little, you are sitting on top of a high reving engine. you're sure it's more than the average vibe?

 

All bike will vibrate a bit at certain rev ranges. Barend weights will help.

 

Yes I'm sure its more than the average my brothers f4ibjust barely buzzed my is far more severe. Snd its not just in handle bars its in the tank as well. As yes have checked all bolts. Was told u were suppose to tighten motor mounts in certain pattern couldbthis he true with installation of cage

 

cage and bike are in good shape no signs of it being downed. and havent took cage off cuz im unsure how difficult it will be to put the motor mount bolts in

 

anyone?

 

since it does ot sitting ther not moving it is most likly to be in the motor..i would try to find out if tghe motor has ever been gone through..i would get the vavles checked if its still there i would be looking at the crank shaft..

 

yea thats what i was thinkin. just dont want to go internal. but looks like its my only choice.
