Go to Steahly's website for a FWW. Get the heaviest one.
I know i could mess with the jettin, but then you get into fouled plugs etc... i would also like the bike to stall less at slower technical speeds.
I found that correct jetting made the
biggest difference in smoothing out the power, though. You can greatly increase the bottom end, reducing the 'hit,' and getting much better lugging capacity when you get all three jetting circuits dialed in. Jetting will eliminate the plug fouling completely. My bike will idle through a whole tank of fuel, if I would let it.
Search for "jetting" and "two stroke jetting" threads here. You'll learn a lot, and end up with a much more ridable bike. Read your owners manual, also. Lots of good information on correct jetting there, also.
The best solution for the stalling issue, though not cheap, is a Rekluse auto-clutch.
I also highly recommend the new FMF Q-Stealth silencer.
