Hey everyone I'm new to working on quads and I'm learning as much as I can but I have a question about my main jet size. Right now I'm in the middle of rebuilding the top end on my 1998 blaster because my jet was to small and I fried the piston. I'm wondering what is the proper get size for it. Its bored .050 over with a namura piston, fmf gold series fatty pipe with fmf power core 2 silencer, and the air box lid is removed. I ride at about 350ft above sea level. Any recommendations for the jet size is appreciated so I can so be riding again.I:I

Order a 270, 280, 290, and 300. Start with the 300 and plug chop it after PROPER break in. Meaning heat cycles, retorque head and cylinder bolts, and run a tank of gas through it not exceeding 3/4 throttle. You will most likely end up with a 270 in the summer and 290 in the winter.
