im about an hour and 45 minutes away from you, my parents used to live in Murrieta, the 140 main jet, stock pilot jet, 3 turns out on the fuel/air screw, air filter cover off, and a tiny shim under the jet needle, along with a FMF exhaust, and the bike ran so much better and stronger then stock.


did you do this mod allready?

this is a must, as they are hard to start when stock.
