anyone know the stock jet sizes for the predator.? getting ready to make some changes with the intake and need to order a bunch of jets to tune it in..

 

Most Predators come with a #150 Mikuni high speed (small round) main jet and a 42.5 pilot jet.

 

i couldn't say the pilot size but the main is 150 and it is the the small round head. if you end up with the large round head they will not fit into the brass sleeve in the bowl of the carb.

will the old mikuni hex shaped jets fit this carb.? i have a whole pile of those left over from the old dirt bikes and banshee days..

 

i couldn't say. i'd probably try it myself but wouldn't tell anyone else to try it. 2-strokes use alot bigger jet than four-strokes though. i've never compared the threads on them before either. the predator jets fit into like somewhat of an emulsion tube or something. in order to get a hex jet tight you have to put a socket around it. the small round head jets have a screwdriver slot that you can put down the tube to screw it out. does any of that make sense?

makes sense , guess ill just have to take a look at the carb and see when i get to it..
