carb jetting

[Greenrider26]

I,would like some advice on jetting.I have a 2000 kdx200 with a fmf gnarly pipe and powercore cylencer,mild porting(polished exhaust and cleaned intake etc.),boyesen reeds,moose reed spacer,and the airbox lid modified. I live in Massachusetts and do alot of trail ridding,the ave.temp during riding season here is between 60/80 degrees. I'm running sonoco 94 octane and yamalube R at 32:1.Any suggestions would be well Appr.

First...what's the problem? You haven't given anything to go on as far as it gags when giving it gas, or it's fouling plugs and it would help if you let us know what brass your running now.

'fmf gnarly' doesn't mean anything. Both the profiles made by fmf for the kdx 'H' model, the -30 rev and the -35 torque could be noted as 'gnarly'. It matters, cuz the jetting is different between the two, the rev taking a richer set.

Check the thread at the top of this forum for 'in the ballpark' specs. You'll find what you need there.
