I would check my bearings. There should be very minimal to no play, axial(side to side), on the inner race. Also, a bearing can become elliptical(kinda egg shaped) on the outer race from an over tight chain or belt or any heavy loads over a period to time. You may hear no noise.Hi Richard,
I've still got a slight vibration. When I raise the wheel so that I can spin it by hand, I get a vibration on the left wishbone. I removed rear brake, front pulley cover and same thing. I don't feel the vibrations anywhere else. I loosen the axle nut and vibrations are a bit less but still there. The belt is not rubbing on the sides of the pulley. The alignment is pretty much the same on both sides. A hair away from the 3rd notch. Do you figure it's still tension? Bad bearing? Balancing?
I recently replaced the tires myself and did the balancing the DIY method using Jack stands as a support for the tire axle. This thing is driving me nuts.
Sounds like you need to find a mechanic who knows what he is doing.Hi guys,
This whole thing drove me to the point of questioning everything. I decided to bring my bike to the dealer and have it properly balanced. Did both wheels and at the same time did the belt tightning. $100.00 later and the bike is worst than it was. Now I've got vibrations in the handle bar floorboards, da da, dada. I feel things on acceleration, deceleration etc. At 60 - 70 my odometer numbers and mirrors slightly shake. Over these speeds...well forget it. Things just don't feel goog at all. It was much better before I took it in.
The balancing they did added weight galore to both front and rear wheels. They more than doubled what I had. On the rear they placed 6 (7g) weights all to one side and directly at the valve stem. Front they added 4 weights.
The belt is so taunt that when the bike is lifted up so that I can freely turn the back wheel, I can only do so by getting my fingers into the groves well below the tire and pulling with a hard pull. At that I'm lucky to get a full turn of the wheel. It looks as though the shop also tightened the axel down way too tight. I don't get Kawi's rating of 1.5mm deflection at 10lbs?! I'm still getting this strange drrr sound that can be heard/felt on the back "wishbone frame" left hand side and now my luggage rack.
The wheel spacers have been grease all the way inside of them to the outside against the forks/nut mounts instead to the bearing seals gasket. You can see oil dripping from the outter parts of the front wheel spacers.
My back pulley wobbles quite a bit. Have you guys noticed this? Looks like my belt goes all over the place. At different stops along a run I can find it in the centre, on the eoutter edge, etc. I don't understand the wobble. If I cup the pulley and try to pull/ push side to side it doesn't budge. With the bearings, shaft, etc...how can it wobble this way? How can the belt move this way? Something just doesn't meet the eye.
Needless to say I'm in despair. This thing is crushing me so that I'm losing the inner gift of motorcycling. I don't want to ride anymore.
For now I've ordered the "Marc Parnes" balancer system (www.marcparnes.com) and awaiting it's arrival. I'm going to redo both wheels. I'm going to video tape it as well to show the M/C shop owner. I'm also going to take apart the back wheel and inspect everything. Pulley, bearings, Coupler,rubbers,etc. Something is just not right. If you guys haven't seen this site www.bikebandit.com check it out for a great parts breakdown amongst other things.
Have you guys done any "Runout" tests on axel/rims/rotors/etc?
Any other ideas are much appreciated.
Thanks for keeping on with this thread I can use all the info/support.
