anything burned on your pipes will probably only be removed once hot....
I normally just use a soft cloth, lots of elbow grease, and get the pipes reallly hot.....
What ever you do stay away from anythign abrasive (even slightly abrasive), it will skuff the beautiful chrome....
Colonel Brassy comes in a white plastic bottle and removes melted rubber shoe soles from pipes and doesn't scratch them. The only place I know of that carries it is my buddies bike shop www.absolutecycles.com
I use brass casings to remove (scrape) the crap from my harley pipes. Doesn't seem to hurt them. Brass is softer than the chrome. I haven't had the occasion to have to clean the pipes on my M in that fashion.
I had the same issue when I first got my bike, but it was melted rubber from my wifeâ€™s boot.Â Someone suggested oven cleaner as well but when I went to Wal-Mart to get some it said right on the can not use on chrome so it scared me into not using it.Â I also got suggestions for WD-40 and carburetor cleaner.Â Tried both and the carburetor cleaner worked the best.Â The thin sections of rubber wiped off almost immediately while the thicker sections took multiple applications and some elbow grease.
I've got one for you NOT to try: I figured: -- rubber (from my old lady's boot heel) got ON there with HEAT -- therefore: use heat to REMOVE it. Got out the old Burns torch -- stuff came off like a charm. BUT, -- I got it a little too hot, and discolored an area of the pipe.
I had this info bookmarked from a Vulcan Riders Site when I used to ride a Mean Streak. Hope this helps!
Recommended Methods For Removing Melted On Rubber & Plastic Items From Your Chrome Pipes

Vance &Hines recommends Easy Off Oven Cleaner. Spray on with pipes cold, start bike, get pipes very warm, stop bike, let cool a little then rinse off.
(Gadget Note: ONLY use the spray on type cleaner. Using one of those Lye based brush on products will melt all of your aluminum and permanently scar your billet)
This oughta ruffle a few feathers, but it works like a charm ... USE STEEL WOOL!!!! That's right, I said steel wool. All you do is get some warm water/dishwashing detergent solution or WD-40, soak it up in the steel wool, and have at 'er. Oh ya... use fine steel wool, and use moderate pressure. Just make sure you keep it wet and it will NOT scratch. I have been doing this for over twenty years and have never had it damage my chrome AT ALL.
Works great after long and particularly bug infested/road construction tar covered bike trips. If you're worried that it might scratch, test it on some old chrome doo-dad you have lying around or in a hidden spot. You will be pleasantly surprised. It works better than anything I have ever found for restoring any chrome to that "show room" gleam!
Use "Brakekleen" solvent, available at any auto parts store. Just make sure the pipes are cool, and DON'T get this stuff on paint, since it will remove or at least
soften any painted surface. Spray the rag, then apply to pipe and rub. Don't spray directly onto bike. I continually rub my black chaps on my rear pipe and stain the pipe. Brakekleen gets it off every time.
I have dealt with this on several diffrent bikes and found that Easy-Off oven cleaner on a warm pipe works perfect. Be sure to test on an area out of normal site and mask off any painted parts that could be exposed.
I had the same problem on my royal Star some years ago. I tried everything - when warm or cold - nothing helped. I eventually used fine steel wool - like you use in the kitchen for pots and pans - worked great -not a scratch on the pipes.
