i agree. 280 is prob the largest you'll need. remember that in order to check the jetting condition of the main jet, you have to check the plug at wot. that means that the LAST couple of combustions on that plug need to be at wot. so you have to crank the throttle open, let it rev up and hit the killswitch and pull the clutch in at the same time. this is best done on the road under the load of wheeler and rider, and not just w/ the ass end lifted up.
otherwise, you'll be getting the condition of the needle and pilot circuit all confused w/ the main circuit.
also, you HAVE to tune your pilot circuit before putting your attention to the main circuit because changin the pilot circuit will affect the main.
one more thing. if you plan on removing the lid in the future, you're gonna have to rejet when you do that anyway, so just do it all at once so you don't have to rejet twice as many times.

ok i took my carb apart and it had a 230! in it for a main jet, and it was like that for a while i think with the fmf exhaust and stuff i hope the motor is ok, the person also had a "custom" skrew in for the idle adjust and the pilot jet was in very far and the end was twisted off. i got all this stuff fixed now. after i put the botseen reeds in it i put a 270 main jet in it and the spark plug was a nice golden chocolate color so i think its ok now. thanks for the help guys.
Here is a question, I have a Dynojet kit and it says with lid on and stock or aftermarket filter with a pipe you should be at a DPX220 which Im assuming is a 220 main size. Stock is a 230 or 240 depending on year or elevation. Now this kit also says that with the lid off you should be at a DPX360. To me that seems like a huge jump. So does DynoJet label it that same or are there numbers different? They look like OEM jets.
the only real time you need ta re-jet is after a pipe or reeds or motor work...other then that dont mess with it
i dont know anyone who runs a 360...thats fukin huge...i know some people with super modded blasters and they only run 330 max
