I came to a crossroad last race season. Either put a lot of time and money into a bike that I didn't own to make it competitive in a faster class or send it back to its real owner. I chose the latter. We decided that as it has been such a good bike for production class we'd offer it to a new rider to get her feet wet in 2 wheel racing. It has been a very reliable bike with the exception of the clutch and I expected nothing less with her on it. Unfortunately, first race it holed the piston. I have the bike in my barn and will do a post mortem later this week.
My question is as I expect to find a bunch of alloy bits in the sump and hopefully nothing more, should I do a complete motor strip or should a really good crankcase flush be ok? There is a return line filter so the big end should not have gotten any junk in it. Obviously the oil pump would be cleaned along with passageways and lines.
