Don't want bashing just curious if any one has compared the kits head to head? I have been on and around Northstars a bunch and only have good things to say about it. Unfortunately I haven't even been close to a rk tek kit but most reviews seem to be positive. On the fence for which one to do? Any added info or experiences would be great.

Its no secrete that Kelsey and I dont see eye to eye however his pistons are Top Dog. They measure up better with relief in the right areas. Highly suggest those,,
I'm running a set of his direct replacement pistons in my cfi 4 motor and after 500 miles I pulled the head and everything looks great. Picked up 300 rpm from them running the same set up as last year. I was leery of running the forged pistons, but have had no issues. Runs smoother and pulls much stronger than before. Additional rpms must be from better cylinder seal, as the oem pistons always had tons of blow by. Personally I like this solution the best, as it keeps the good secondary compression that Polaris designed into the motor. I don't like the idea of shimming the cylinders if you don't need to. Plus if you had a problem while on vacation, you could always switch back to stock pistons if you had to.
