I've been fighting to get my wife's bike tuned, even decently, since we bought it. It's always run mediocre at best, and stalled all the damn time on her. I was only able to keep it running when I rode it, with quick clutch and throttle hands. Tonight, as I have on several occasions, I took it for a WFO run to try to clean out the exhaust. I got some smoke out of it, but not much even though the silencer was super hot to the touch. The bike has had spoogy oil dripping from the exhaust since I got it, so I decided to take it apart to clean it out and repack it. Hoping I will be able to get it tuned after this. What is the best/safest method to clean out all of this oil? Trying to burn it out with a MAP torch scares me a little. Isn't it a little chancey that I'll melt, or at least severely weaken the aluminum?
