so i had a little issue with a strong misfire that would lead to stalling out after. it seemed like it would only happen when the engine was hot or when i hit high revs while riding and then let off. there were a few occasions where i would try to start it again and then the battery would almost be completely drained. i ended up going all out replacing the coils, the ignition (dyna s), and eventuallly the entire engine as i wanted to have more spare parts on hand or to rebuild so when one engine messes up or needs a rebuild i would have one to drop in. well after all of this was done it seems like the misfire hasnt got any better. i pretty much chainged everything but the carbs which have been cleaned, the wire harness, and the rectifier. would the rectifier cause a misfire for any reason. im looking for any ideas as to what may cause this to happen. the riding season is almost at its end so any help would be halful at this point.
