This spring I bought a 2012 pro rmk with 1000 miles on it. My plan is to run it next season as-is (stock with gear down and minor clutch work), and then do a fix kit next spring. But doing research, I found that the RKT 858 kit is not a whole lot more than the cost of these fix kits. I'm curious about these, those that have them and have been around them, how do you like them? How has reliability been? Is it easy to tune? Did you do the rkt cheater heads, and what's the standard option without the heads?($100 cheaper without the heads). What fuel programmer did you go with? How easy is the install? I don't have a ton of experience as a mechanic, but I'm good at figuring things out (I'm in college studying MET). Thanks in advance!
