I have a 2001 YZ426. It runs alright but has a ton of decel pop when i let off the gas at just about any rpm. From what I gather this means the pilot jet is too lean, it had a stock 42. I replaced it with a 45 and it may be a tiny bit better but its still bad, so i need a bigger jump. I noticed the bike has pretty much no popping when i have the choke on, and still runs pretty well, so instead of just buying one jet after another, does anyone have an idea how much of a jump in pilot jet size it would take to equal turning he choke on? Should I try something in the mid 50s? Higher? Is that just too high? Thanks!
