ok so i have yet to figure this out. altho it has gotten really odd now. it only cuts out at WOT, and is completely random, some days can ride all day without a problem, others 15 minutes and its done. so yesturday i was riding, it happened, plugged the gytr tuner into it, read the computer totally normal. tp is 0, all temps normal, no codes. took off the tuner went riding, didnt have a problem the rest of the day. so after about 20 min of hard mx riding, 2 minutes screwin with the tuner nd went bak out, its completely normal. ive cleaned the fuel pump, injector, tb, tp sensor, checked all my wiring, no exhaust leaks, no air intake leaks. air fliter is clean, fresh oil, fresh gas. runnin vp's c12 for my cp 13.75:1 piston. anyone have any ideas? its driving me insane!
