[QUOTE="TheChasers, post: 230982, member: 3831"] Not that I noticed, was still popping after. Didnt know what next steps to possibly fix and recall a few people on another thread saying some pilot screws dnt seal properly, so I changed the WorksConnection screw out with a Bikemasters I had just grabbed for extra while at Chapparral and now about 2 to 2 1/4 turns out I have brought the popping down, not completely gone but I will hear a single of double pop on decel after hitting 3rd gear here and there. So Im still gonna be tweaking it. A little confused on how popping is supposed to mean Im too rich because too much fuel going into exhaust, but the only way I can minimize popping is by richen out PS screw, if I lean out pilot screw popping increases until I eventually rich a point of backfiring. Some guy on another thread that does alot of jetting is saying it has alot to do with needle and that I should change needle to a D series needle so gonna try that. Someone else suggested to check accelerator pump so Ima get to that too. I seen a few people online say that almost all Yzs pop on decel and that its normal, but I dnt know if that just gave up on properly tuning their bikes and accepted that or... So Im just trying to do all this testing to figure it out and hopefully it leads to me completely getting rid of pop. [/QUOTE]
