i am ready to do the m 1.3 conversion using the m90 motor and someone told me don't do it because of the short stroke of the m90 while the b35 is long, and that i would not work. Is this true or they are full of !@#$. i got the tooth harmonic balance on it and the tdc marks line up the same as the old one

They're full of it. A 2MM difference in stroke isn't going to make any difference. What would theoretically make more of a difference is the difference in shape of the combustion chamber. But even that's similiar, just not the same with the odd shaped B35 piston. You've still got an AFM measuring air, with added inputs for temp and throttle position, it will work.
