I found the cap of a gear tooth inside my magneto when doing a timing chain change. I Will dismantle as far as I can go on the clutch side of bike to check eveything out. If I cannot find the source should I bite the bullet and have the cases split? If everything runs fine and there is no noticable problem would any of you sell the bike without mentioning it? I bought the bike used and overhauled everything including top end. The only thing I didn't do is split the cases. I feel I got taken to the cleaners with this bike and am beginning to want out!
