K20, I recently scored a DR 500 engine that had been raced on road racing.
Both balance shafts and the kick starter shaft have been removed.
I haven't actually ridden it yet but that won't be far away so I'll keep you posted.

Ive left them out on 250 engines. Give it a try and see. Honda are generously engineered so I dont think it would cause a major failure.

On the XR It reved quicker for sure only good for motorcross, With 250 XL motors I turn down the flywheel allot and leave the balance shaft in.
