Just got my pre-mapped Dyno-jet from Fuel moto & installed in my 05RK. All I can say is Holy s#%* what a difference, took for test ride, no more popping & coughin',throttle response is improved. What a change can't thank Jamie& Keith enough, one of the best purchases I've ever made.

 

I bought the Power Vision from Jamie. Major improvement!!!!!!!!! Also one of my best purchases.

 

Yup, I put the FM EFI Tuner on my bike and it ran like a dream! I have since reduced the idle speed (1100rpm just seemed too high) down to about 925, but the rest I left how they shipped it. Fantastic product and company!
