Hey guys. Going on my second season with my ‘96 XP. Bought it with a spec 2 pipe with the water injection, pro k arrestors, Solas X/O impeller. This year I put a ADA head on(175psi), buckshot rotary cover, buckshot 46 carbs, msd enchancer. TDR waterbox. Koso egt gauge and R&D 85/88 nozzles. Last year I could get 7250 rpms out of this thing but after all the add ins I cannot get much over 65-6600. My jetting is 105 high and 120 lows. Seems buckshots are reverse jetting. Pop off is 21psi. Water lines to the pipe were not jetted so I tapped the fittings and put 125 jet after the solenoid and the mid pipe as well. Mikuni fuel pump and a 80 jet in the return. Timing is +3 degrees and at 5000 it pulls back 10 to a max of 8000. It does have some oil leaking from the rave valves now so I need to address that but would that affect rpm that much?? I’ve read that the buckshots are a pain to tune. Seems rich from idle to 3/8 throttle then clears up. Plugs look acceptable and egts are about 1000-1036 max temp. Thinking of ditching the buckshots and putting the stock ones back on. Any ideas guys?? Thank a ton!!
