What rattles ? piston slap or bottom end noise ? .

I have a running K1b that has a noisy bottom end , not sure what to do there as I think it's the original engine and I hate to swap serial #'s unless I have to...

Maybe I shoud _ride_ the dang thing and see how bad it really is after a long hot ride .


Don't know yet.  Maybe piston slap.  Only after it warms up.  Will investigate further next week.   For now I just ride and bear it....
