Yfz issue! Please help
2012 Yfz bought used, with pipe and air box, with wiseco programmer, running fine one day , then started acting like the tip sensor activated, missing and bogging and would only idle for a few seconds,, replaced with KMS eliminator , nothing helped, new fuel injector, fuel pump assembly, TPS, checked stator, crank position trigger, checked timing, replaced plug, checked valves, ......... I AM AT MY WITS END, even paid an Atv shop a lot of money to only have them scratch there heads...help please. I can keep it running now while working the throttle and with only the MSD BOX on that I also replaced along with a new CDI box, crazy ,
