So i recently bought a 85.5mm bore freestlye ported (lenzi) port by Lamey and i dont have the money to buy some good 44's or 46's at the moment so im going to run my stock 38's for a while...does anybody have some ballpark jetting specs for me that i can atleast start from? boat has limited b-pipe, advent ignition, stock lightened flywheel, i believe 35cc domes-185psi compression, and vforce reeds. thx! oh and its a regular sj motor going in my 05...61x cyl, 62t cases
