&@#$*!!!! Need help diagnosing electrical problem
I've been having a problem with my YZF750R that I can't seem to diagnose. I can ride for a little bit fine, but after about 10 min or so the bike starts sputtering, backfiring, etc. Gets worse and worse till bike shuts off. Once it cools off, I can start and ride a bit more, till heats up again. I replaced the coils (with used ones off a low mileage bike), and than it ran great for about 2 weeks then the same thing happens again. I ordered new caps, boots, coils, and replaced everything with new OEM parts but the problem is still there. Any help diagnosing the problem would be appreciated.
