according to the recipt, it's # FMC PM3 It's now in a red and white can. The lable says carborator and engine cleaner. The stuff is really thick. You should pour some in your muffler while it's off the bike, slosh it around and let it soak for a while. I just did it some at lunch, and it really cut thru the crud. Now, I stink at work. Oh well, it's not the first time.
The can was about $5.00, when I get home I'll break out the cheapo can of carb cleaner and use the spray to clean everything out.
