May 8, 201511 yr I have acquired an early 125 minarelli fantic engine Upon removing the clutch cover I noticed the clutch basket has helical cut gears like a 240 I have had several of these engines apart over the years and have a couple in bits already but as far as I can recall I have only seen straight cut gears. If I take them apart I put a felt tip mark on the crank pinion and the clutch basket so they go back in the same place and hopefully don't chatter and rattle at tickover, so I am sure I would have noticed in the past So, did the early ones have helical gears ? And if so is there any other differances ?

May 8, 201511 yr Author never thought to count .... I suppose if they had thought about it, when they designed it they could have done the math and made a hunting tooth ? just something I do, keep the same surfaces together (or not...) wont do no harm, the point being I remember all the others having straight cut teeth and this one is helical so, is this unusual (the helical bit, not my felt tip pen malarkey !)
