I didn't send in the warranty on my TT so I am stuck with it!
If you have a receipt less than three years old from an authorized TT dealer you are still covered with a warranty...tear'em up!
If not...well...yes...you are stuck with it.
IMO, the Magnum .52 won't handle the higher RPM's any better...the same thing will probably happen at some point in time. The 'sport' engines simply don't come with bearings of the quality needed to run the 'H' out of them. MVVS, Webra, Rossi, Jett, Nelson, etc., yea, run the snot out of them...they LOVE high RPM's!
