2012 Pro RMK Fix Kit?

[Hansen13]

Hey wondering who has installed any "fix kits" as they call them. Was gonna do the sled up with a terra alps kit this year, but going to ride it one more season than upgrade so not looking to spend a ton of cash. Has anyone does the wiseco kit? Or have any preference that's a fairly reasonable cost?

The MTNTK fix kit is the only kit you should be looking at. all the other companies copied them. The Wiseco piston is great, you just have to make sure that the sled is warmed up properly to avoid any cold shock on the pistons. Forged pistons expanded a bit more that cast and can case scoring problems if the motor isnt completely warm before you start running it hard.
And stay away from Terra Alps.... might as well burn your money!!

I've had great results with mtntk.

Bought "fix" kit from hanson racing, wiseco pistons and shim, just like mtntk.

Bad experience with terra?

There are a lot of kits out there trying to copy Mtntk but have not seen one that works as well and is as dependable as theirs.

Bad experience with terra?

I haven't had any personally, but know a few guys that have had some real bad business with them.

Ok, have heard something about bad customer service there. But rumours is rumours, not sure what to belive.

Subjective data - two most popular "fix kits" around here since the 2011's came out seemed to be Indy Dan's, and RKT. Not talking big bores. Different approaches. Neither have been perfect. Most customers I've seen have been pretty pleased. FWIW.

Thanks for the replies guys, I've heard a lot of ups and downs to terra alps. Not their product itself, but solely customer service. What I'm most looking for I guess is something I can order in Canada. Our dollar is so bad right now I'll pay out the *** for something in US $. I will though look into MTNtk kits. And yes I run the forged pistons in my old sled, and they seemed okay but you're right, long warm up times.

Has anyone ordered the kit through Mongoose Machining in BC? I see it's about 650$ canadian through mtntk, but shipping is expensive too. If I can cut costs on shipping then it pays for my gaskets etc..

FWIW, the whole piston expansion between forged and cast pistons is complete bs. The aluminum used in pistons is an alloy, as is all useful things made from aluminum. It can easily be formulated to minimize expansion. The expansion difference between cast and forged pistons is well within the tolerance spec.

With that said, never let a 2 stroke engine sit and idle for a long time. That's actually much harder on it. It also fouls plugs. Just run it, but don't hammer on it until it's warm.

You would think that the expansion would be a little bit more uniform .
