I PUT A BLASTERII 760 IN AND HOOKED MY FACTORY "B" PIPE AND NOW IT OVERHEATS. @100 YARDS THE CHAMBER GETS @400DEG. I TRIED TO ADJUST THE TUNING SCREWS-DIDNT CHANGE ANYTHING. HEAD TEMP IS 165. POSS HOSE ROUTING? I CALLED FP AND IT APPEARS TO BE PLUMBED CORRECTLY. ANY HELP WOULD BE APPRECIATED!

you may have to clean the ajustments screws on the pipe these is very normal if you run on salt water

go through everyone of the fittings. i had a riva pipe burn my exhaust hose, could not figure out why just by looking at the fittings. took the pipe apart and found a small sliver of wood blocking one of the brass fittings. it was actually inside the fitting, so you could not tell just by a visual inspection.
