My Biturbo is not old enough to need cleaning, but definitely do not put it, or any other pipe, stock or aftermatket, in the fire. The rivets that hold the can on can be drilled out, then you superglue nuts to the inside, and use machine screws to reattach the can. Clean the pipe with Castrol Superclean, or Greased Lightning from Home Depot, being careful not to get it on your hands or in your eyes. Either one of these products is great for removing oil and carbon deposits, they are like super strength oven cleaner. As for putting a pipe in the fire, I have no idea where that came from, although I did find a reference to it in a book from the early '70s about how to maintain your dirt bike, if you were way out on the trail far from civilization, with a plugged up pipe. Contrary to what almost everybody (except donp) says, the Biturbo is a decent pipe, and should last many years. It also looks great on my Sprint, instead of one of those technowhatever curly q pipes. I would recommend it as a replacement for anybody who has a Tomos with one of those catalytic pipes. Peace. Jerry.
