Hey folks, new guy here. Here we go , I got a 96 Polaris 500 sportsman been a project for a while now, so far new cam (H.O.) & rockers, timing chain, coil, plug wire, fuel pump, piston &rings, primary clutch, belt . Timing is dead nuts, gaps are right .006 . Cleaned and rebuilt carb. Air fuel mixture screw, 2 turns out ,1 1/2 turns out all the same, quad still has no power... Can I go to a 40mm carb, and if I do, do I need to change exhaust? Also going to change secondary clutch seams to be making noise , gone this far why not. Am I chasing a unicorn here , will this ever have any real power? If so , how do I achieve it?
Also new air box and lid ,
