i just got a B1. its got a blackjack carb, FP limited pipe, and protec rec head.
i looked at the cases and cyl. case has 6M6 casting marks and the cyl has no casting marks that i can see, on my other two skis with 61x cyl's the 61x mark is casted between the cyl's on the carb side. so i don't think its an X cyl... but what could it be?
so is this a 650 or 701 motor?
the owner didn't seem to know much about motors in general, he says the motor is all stock except the head...
so if this is a 650, and its stock except the head (145 psi) how much of a difference would i notice from changing it out to a stock 701 61x/61x using this carb and pipe.
i guess if i did swap in a 61x/61x i would need a FP exhaust mani for the 61x cyl right?
