what jet should i run

[yamahablaster01]

i took the jet out of my blaster and it had the stock 230 and that seemed too small. what jet should i run my parts are fmf fatty pipe powercore 2 silencer, weisco piston (20over) boyseen reeds, k&n airfilter,

about 270-300 it takes alot of trial and error to get it dialed down perfectly

 

[blaster195]

it might even be higher then 300 and it could be lower then 270 but try them and in between those 2 numbers and dont forget to check the plug

I am running a 250 main with a FMF gold series fatty and Powercore 2 silencer. i am sure you could probably get away with a 260 main. go to fmf.coma dn they have a jetting guide that tells you what jet to use depending on what mods you have.

hope this helps
