« on: July 22, 2010, 06:56:19 pm »
Afternoon all ,I am after a bit of jettin info on a CR430 83 .The bike is a bit of a mystery job.XC long swingarm etc and a standard carby with a methanol booster jet in the throat & some mild porting to transfers
I expect the yanks may have using it as a hill climber .Its been apart and under re construction
I would appreciate some middle of the road jetting info to start from and I only have 390 info at hand

 :D Gday Boots,
                      Book settings for a 430 are;   Mikuni 38mm
                                                              Main jet 440
                                                              Needle jet Q-8
                                                              Idle jet 45
                                                              Needle position #4
                                                              Air jet  2.0
                                                              Throttle/slide No.2.0
                                                              Needle 6DH3
                                                              Air screw 1.5
     If its been running on metho I would check the ignition timming it may have been retarded it should be 2.2mm before TDC.         ;D Happy Kicking
