So I was working on tappet clearances, trying to move shims around to reduce the number I need to purchase. I forgot to put a shim back into a bucket before turning the crank. The edges of the empty bucket shaved material from the edges of the cam lobe. About .75 mm on either edge of the lobe was affected. The lobe should still produce the same amount of lift right? It?s just the very edge. Or do I need to replace or have it machined? 82 GS550L BTW

I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.Comment

I think I agree, the only problem I can imagine would be faster wear on the lobe from reduced contact area with the shim. I reckon ill just fuhgeddabouditComment

Personally, I would take a very fine file or maybe even a stone and drag it at a slight angle from the center of the lobe toward the edge. VERY lightly drag it, just enough to make sure there are no high spots.Comment

Ooo good idea, the scraping could have raised an edge.Comment
