If you ever come to a Mich. GTG, I think it would be great fun to have a 50cc shootout, especially if a certain MMWS ported 346 is there along with your 550!! Last year I tached the 346@15,500RPM & still very clearly 4-stroking!!
Oh yeah, I would also bring my 562. It doesn't need porting! It sings a pretty song with just a MM.
