my bike has some unique problem which is very difficult to explain here.
which i guess is due to uneven power transmission during disceleration or some problem in fuel and air mixture injection to the engine.
I changed the crank, piston bearings and rebored. but the problem did not resolve completly.And even iam very unsatisfied with the sound and pick up.
if you could give me any really expert technician's number whom i can consult, will be a great help to me
