hmmmm.... I always heard people surmise that 4 strokes developed LESS muffler pressure....

I have heard the same and will post the muffler pressure of a 91 Saito on Thursday. Must pick up a header that was broken.

Generally I am finding 45 size two strokes to develop from 12 t o17 column inches of water (about 1/2 to 3/4 psi) depending upon the muffler.
