300/440/550 1994 750sx does it have......

[550headache]

does a 1994 750sx with a mikuni SBN 44 have or supposed to have a tank check valve? my buddys has a factory wet pipe and the low end is all screwey. my 550 had a low end bog and it was from a poor check valve. wondering if the 750's are the same.

I thought all skis had check valves on the tank....

it SHOULD have a check valve, but may have got lost in the last 15 years
that said, mine was stuck wide open and I worried about it
replaced it and it had NO effect on operation of the craft
so I dont think that is your problem
