I have some real old 1970's trial bikes that finding engine parts in either factory NOS or aftermarket is nearly impossible. The pistons are pretty tight as of now and I want to keep them that way, what is the BEST 2 stroke oil money can buy?
All old strokes I see have major piston slap, some are even oil injected, so that leads me to believe they were either beat hard, or not mixed or cared for properly.
Is synthetic even good to use in such old bikes?
