i have a mojave 250 that has a white bro's e-series exhause, has been port and polished. i think my jetting is off and i was wonderign what jets i need to use. when i try to climb a hill, i will be holding the throttle all the way and i will be just idleing. what is up?

 

has it been jetted at all?

 

it depends on your altidude and alot of other things also, there is not just one jet size that we can tell you to put in there based on the mods done to your bike. your best bet is to take off the float bowl and see what size main jet is in there now and then go to your dealer and get the next 3-5 sizes bigger then what you got and just ajust it untill you get it right. if your plug is white you need a bigger main jet and if it is black you need a smaller main jet and the same goes with the needle if the plug is black lower the needle, if its white rase the needle.
