YS 140 FZ conversion to L

[VicenteRC at aol.com]

That means that the crankshaft ring for L is different and won't fit.  In other words, Do I need to order the crankshaft ring for the old 120 SC?

Have you perform the conversion?  I have the opportunity to check both engines same conditions and the L is about 400 rpm stronger.  What is your experience in doing the conversion?

Thanks for your help,

Vicente
