Rebuilding carbs on my 2000 xpl 951......lowering pop off due to adding an RD flame arrestor. I can get pop off within 2 psi between each carb but it requires me using 2 different gram springs. Black 80g and silver 95g in the other carb. Is this normal or do I have something wrong? Everything in the rebuild kit was genuine mikuni. 2.3n/s setting pop of to 18-20psi. Thanks

951 Pop Off Mismatch

Ski came with an RD FA and was not jetted properly when i got it so I am trying to fix the jetting.....From what I read when using a FA that creates less vacuum pop off also needs to be lowered......i had a hesitation off 1/4 throttle with 95g springs last year. But when I try and use 2 black springs each carb pop off is and 5lbs out from each other. 20psi and like 15 psi. Were numbers I was getting
Are you a skilled rider?
Do you let anyone else ride your XP?
I ask because it is easy to roll that ski and it is even easier to ingest water with that ski which will kill a 951.
There is no performance to gain with the R&D.
IF it was me I would get a stock A/F and use stock jetting.
But the carb comes with 95 gram so I would try 80 gram. Or 2.3 needle and seat with the stock springs.

Id consider myself a skilled ride this is the 2nd xpl I have owned along with 2 96 xp's and a 97 spx and a js550.....but i do see what you mean! I have outerwears as well for what its worth. I do roll the ski because I ride the snot out of it and i didnt injest any water last year. Jetting now is 80 low 167.5 high with the 2.3ns and still has accel pumps. I may go back to stock FA as you suggested.....i forgot to mention previous owner installed rossier head and aftermarket reeds and cage but still has factory pipe.
Thats what i had in it before 95g spring and 1/4 throttle response was terrible if i worked the throttlw and got it above that it ran amazing.....plug chop was brownish tad rich. Low speed screws made no difference so i assumed pop of was to high.....its mostly a guessing game for me haha
