I have the TM on my 05 RK. It runs perfect with no ping in any gear. 95", Flat Tops, S&S 585 with gears. I'm adding Rhinehart true duals. What do you think of the TM
Well Zippers couldn't get it to work on my bike with the Rineharts. Of course I had the stock cams. The thing would overheat pretty fast sitting in traffic. They worked on the bike for about 8 hours at bike week in 2007. Rumor has it they have solved this issue.
I have had the ThunderMax on my bike for over 2 years now.
I have a 2007 UltraClassic. Rinehardt true duals, Zippers air cleaner and thats it.
Bike runs perfectly. No issues at all!!
