it was fun to see that , I was there in 2002.... a great race to watch. 2 stroke rule!!

I want to know what is the biggest engine with the use of one 35mm pwk carb . With my 350cc ported for mid to hi-rev , the bike seem to be lean all time even with a 220 main jet. The intake do not have leak, all gasket are new. My setup is procircuit pipe,cylinder ported (dune port) open air box with durablue filter, 5 degre of advance on the ignition, 150 lbs in the cylinder , noss head with 19cc dome, ported reed or v-force (i try both). The carb came from a kdx 200cc it as a 220 main, 58 pilot, eek needle in the rich setting. I live in canada at about 500 to 1000 feet of altitude.With stock carb it have 340 main and it is perfect. Thank, mike
