He seems to have fallen off the map. The jetting I posted above where in some 46's i bought off a guy that was running them on an hpe819 with bpipe.

I have 2 of them. I run one with 125L 115H 95 Gram spring and 2.3 N/S. The other is at 125 main and 120l with a 1.5 N/S and 65 gram spring. The motor with the 2.3 N/S is crisper. These are right from Matt at HPE.

I can`t help but comment this looks to lean to me, hold it wide open for awhile and seize? Maybe 135m 115l with the screws 2-3 turns out just to test,
Cool thanks for the input. I’ll definitely get both jet sizes to tinker with! Appreciate it!

It's not. I run 110/130 on my 771 with TL and lay down pipe and have no issues going full throttle across the lake chasing boats etc.

Thats the same setup I have in my Proforce a TNT V3 with a slightly different stinger for topend and TNT waterbox. I have ran this with many different motor combos,carbs ignitions,etc and have stuck a few pistons due to detonation also. It has a strong midrange and I like it going from buoy to buoy, the jetting I have always played it safe and ran around 260- 270 total in each carb and have no experience with reverse jetting. Interesting if it works it works.
