Hey Guy's, I tried ordering a new needle jet for the stock VM38SS Mikuni on my KX250A5, the stock size is R-2, all the catalogues that I've looked at say the type is '166' as opposed to the 159's that smaller VM's run. I received a couple of 166 needle jets but they are miles too short. The number on the jet in the carb is '283' but no listings mention it at all.
The VM38 uses round head (reverse) jets which have a slightly different thread to the hex/159 jet/needle jet. Anyone got any idea where I can get an R-0 & R-2 to suit my VM38 ?
