Woo-hoo! Found the basics thread for dummies!
Was afraid to shim my needle so I bought the KTM LC4 needle and bent it instead because I didn't use the factory plastic washer beneath the clip.
So, removing the snorkle - shimming the OEM
needle with the #4 washer- and adjusting the fuel screw will all result in more air and fuel. ProCycle is using a 137.5 main and Eddie Sisneros (TT jetting expert) says to use the next size smaller pilot.
Has anyone done the above described mods AND also both reduced their PJ and MJ too? If so, the bike would be slightly leaner on those circuits and then richer on the needle where most of the carb is doing its work for most of the uses this bike sees. Agree?
If so, richening the needle (via shimming), leaning the PJ slightly, richening the fuel screw, leaning the MJ slightly, and snorkle removal ought to result in less overall MPG change than just the usual mods w/o also adjusting the MJ and PJ - right?
