Noisey Gear Box

[auzzyss]

Hi people... Are the busa's gearbox a naturaly noisey box on idle in neutral. My is making a rumbling sound on idle in neutral when the clutch basket is engaged. When i pull the clutch in.. the noise goes away. So im assuming that its in the gearbag.... somewhere.

I can even hear it stopped at the traffic lights in neutal with cars whizzing by..

Is there a faulty gearbox problem with the busa??

Its the in the clutch basket, its the back torque converter
Don't worry its comes standard with all Busa's, you can weld it up for the drags. do a search on BLT

Hmmm not too sure on that.. My old TL1000 has a back torque limiter in it aswell and it never made a rumbling sound even while in neutral..

I dont know wot to think about it?!?

The rumbling sound is like a dead bearing/s rumble.. just to clarify.. :)

Pull the clutch cover off and look, some have had a loose bolt issue at the springs, retaining studs have come loose.
BTL is noisy, rattles, not rumble,

If it is a gen II model, there is a new service bulletin that PAN just posted re loose clutch spring retainer bolts.
Same may happen to a Gen 1 model if the clutch has been apart and locktite not put back on the threads.

thanks for the info guys... I pulled the clutch cover when i first got the bike and reset the clutch spring retainer bolts and locktite them in... i checked the slipper and looks normal.. i also done an oil change while i was at it and never used the same oil which was motul 5100.. i put castrol crap in it.. so after talking to a mecanhic at work.. he said to put motul back in with a new filter.. and wala..

THE NOISE IS GONE!!! yee haaaa..

wouldnt have thought something so simple would of had such a big effect.. i guess oils aint oils after all...rofl
