I'm running Power Inc Center dumps on my 600 and my pto plug (next to primary right) has no color so I think is to lean....and the center and mag are a little black with brown tips, So what size jets should I go next....I'm running 140/141.3/140 and 47.5 Pilots.

I'm also running a EGT gauge and It seems fine at Idle and mid range but when I hit the gas the mag side goes way hot I think up to 1400 degrees and the other to are betwen 1000 to 1200 on full throtle, Any tips guys....Thanks

Did u raise your needles? I took out a piston on a 700 running fat jetting & those were the only pipes i ever ran that did that. Raise your needles atleast 1/2 richer then stock right across & possibly a whole clip & go 1 size richer on your hot cylinder.

Turk I never did touch my needles because I was afraid not knowing how to....Could you explain me the proccess..I not even know where the needles are or how to do it.....Thanks...So should I keep the center and mag side jets the same even thatthey are a little rich...and go up one size on the mag side....What would be one up from 140....Thanks again.
