Well i changed the belts on my 916 all seem to go good i did everything by the book. She started just fine but when i got on and began to take off i noticed that the back end feels like its wobbling. Like i mean like if i make a sudden movement im going to crash. Once i get up to speed its not so back but once i began to slow down i can feel it. Almost like if the rear tire is wobbling. Well if anyone can help please let me know. Oh and it didnt do this before i changed out the cam belts.

There is no way that changing the belts caused damage to the rear end of the bike; did you puncture your tire and have low psi by chance?

Anything wrong sounds like a total coincidence.

rear axle nut tight?

I can't see a relation to anything to do with belt changing. as suggested perhaps low tire pressure?

rear brake is locking up by chance?

Don't think it has anything to do with the work you performed. I had the same feeling on mine when the swingarm was loose.

Just exactly which procedure did you use for tensioning the belts? :)

Don't worry about the belts. Look for something else wrong.

I didn't think what I did had any affect. What could have it been. It was fine before the belt change. I'll have to check hub and swing arm.

I check rear tire pressure it's fine. Rear brake not locking up. I used the quarter turn technique. But I just got my falcon d16 today so going back in to check tension.

I wish I knew I didn't touch anything from the rear but spin the rear tire.

do as race teams do:

Take the reaer end apart and rebuilt it.. you'll see soon enough what it is...

keep cool... something mechanical is easy to repair... fear in your head is not :)

i dunno, given that it was fine, then you did some work on the bike and now it's not fine tells me something you have done is causing this. it would have to be bloody remarkable coincidence for something to shear off/fail/break just moments after you start riding again after doing some major servicing on your bike.

I'd be thinking carefully about everything you touched on the bike, go back over it for a double check or triple check and make sure nothing has been left off/loose or not torqued properly.

I just went over it again and everything seem fine except. The rear sprocket wiggles is that normal. Like I can jiggle it with my hand. I guess it was just my luck.

Check rubber mount cushions for sprocket, wear will cause wobbling as they become loose fitting and allow movement.

Will do this tomorrow I'll update then. It's time for bed now.

Oiled up the tire?

Spilled oil on garage?

Your rear sprocket shouldn't jiggle at all. Sounds like a cush drive problem.
