Title: Oil filter cover/case
Post by: BobAndren on June 28, 2020, 07:42:48 pm
Hello folks (again), I've another question related to my sandcast restoration.  It was (gratefully) pointed out to me that my bike, as I found it, had the wrong (finned) oil filter cover/case .   Fortunately , Yamiya offers the  a correct repro . That just arrived and I note that the casting is really rough.  I thought that it would be nice and smooth and shiney but this is far from that. Is it supposed to be a pretty rough casting?  I find it hard to imagine that Yamiya would sell it that way if it was supposed to be smooth as the parts that I've bought from them have been very good to date.  Bob Andren

Indeed the yamiya repros are rough. I have several originals and they are smooth like the engine side covers. Whenever I have used a yamiya oil filter cover, I have always sanded and polished it before spraying it with clear engine enamel.

Bob, find an early un-webbed finned cover, knock the fins off with a hammer, chuck the cover in your lathe, and make it into the best copy available.
