The Husaberg 550 and 650 are infamous main bearing killers. The culprit is the crankshaft, because it is weak and spreads to the shape of a banana when picking up revs. I'm planning on making a tougher crank. It will require you to remove the counter balancer. The left crank web will be thicker, to be able to hold the crank pin better. The right side will have a taller shaft to accomodate a second main bearing in the flywheel compartment. A spacer/bearing cage will be mounted at the right side and then OEM flywheel/stator/cover.
Crank, pin, bearing cage will probably cost 700€.
I'm not doing this with any commercial interest, just fix a known problem and make fellow Husaberg enthusiasts happy!
With this thread I just trying to see if there is any interest in such an improvement?
