Motorcycle Questions? Ask a Mechanic.
Hello, if it's getting that hot it's running lean. (you have opened it up alot with those two modifications) You need to look into a programmer to richen up the air/fuel mix and that should take care of it.
I'm sorry you are not satisfied, I offered a correct answer as to why the exhaust is so hot and a solution. People have many preferances for different types of programmers so I did make that part up to you.
Since you ask for more specifics in your follow up I would recomend the power commander V as seen here and ask their tech support which map they recommend for your specefic set up, they know their product better than anyone else.
That's what I've had the best results with over the years concerning how it works, tech support and general quality of the unit.
