i have seen no information saying the engine makes more power without one, and the post above seems to prove that there is no tangible gain from removing it.

i would, in fact, prefer to have one 'just in case', but haven't seen any failures on the 103 without one... unless this one ^ is eventually traced to the deletion of the balancer.

if anyone can come up with a way of keeping the balancer, and having a toothed wheel,i am all ears, the method of machining the front and pressing a toothed wheel on, as stated above, actually removes the balancing effect, as there is no rubber left.

i cant use the marks on the flywheel, they are long gone woith the lightening and balancing that was done three years ago!
