Wow, I didn't realize the cracked pipe can cause stalling. My 2003 was cracked when I bought it, kept stalling so I bought a tt flywheel. It helped, but didn't eliminate the stalling. This past weekend I was riding pretty hard at some pits and blew out the header...now I will be getting a new/used one.
