[Anthony201]

Hi I have a 02 Blaster bore 40 over stock ,k&n air filter no box and a full aftermarket fmf exhaust .can anybody please tell me what size jet to use.it was given to me by my friend who moved away could not keep it.please anybody help it keeps bogging when you punch on the gas.

Im thinking around a 270 should be close for you.

 

[Anthony201]

OK.thank you bummer981 I am going to by the jet this week on pay day.I hope it works this thing has me going crazy. Because I am dying to go blasting..

FMF alone calls for a #260 main, I would be choosing a #290- #300 to start the a plug chop run.

32.5 pilot and the needle on the middle clip!

Thanks Blaaster

I also need to tune up the carb I don't know the proper screw setting

The " proper" is what it wants, needs. Start at 1 1/2 from lightly seated.

^^^^what he said. You will need to change jets for colder weather as well, so better to have a few on hand
