It all started when I was riding on the highway running about 135mph. My oil light came on, and looked behind me for my friends, and all I could see is a cloud of white smoke.
I pulled off to a gas station only about 2\10 of a mile down the road and filled up with cheap oil. it was smoking the way home because of no breather hose.
The next day I did a regular oil change, and there was nothing too alarming in the oil, or filter. But it continues to run like rubbish.
My top speed was 135 MAX and took awhile to get there. It bogged down while idling, backfired constantly just little burps, and generally sucked to ride. A friend suggested i may only be running on 3 cylinders.
I pulled the plugs
Bad plug would be on the left of bike.
edit: the battery is on its last leg, that might have something to do with it.
SOOO I replaced the plugs, and regained some power, but not all of it. I still have poor low end power, medium mid range, and after about 7000rpm it runs okay. while I was in there I cleaned the carbs, checked the seals everything was good.
maybe I did not seat the carbs correctly..
