So what is the best way to remedy this? I am leanin towards doing a fix kit and would lik to check clearances of cylinder skirt, and tighten up if possible. How expensive?

Wow, I wonder if these are the new made in Mexico domestic twins? Polaris was supposed to move their snowmobile engine assembly plant from Minnesota to Mexico to cut cost. There was an article in snowest about it. Made me so mad i am ready to switch to cat!

Pay attention walmart shoppers! Stop buying cheap junk...

this applies to dragon and all other 4 injector motors, Pro rmk motors have been aOK in this area.

Best way to fix it bar none is the carls 860 kit using the separate jugs like the 600 and 700 motors, and you get 175+hp to boot price / about 5000.00 +/-

fix kit seems to do the trick as well, i'd go with a 2010 monoblock tho, thicker bottom webs (case will need to be bored)

I have a dumb question does the 11 SBA have this issue, just wondering how the pro rmk is A ok. I'm just reading about all this because I picked up an 11 SBA with 275mi on it, and have already talked to Kasey at RK Tek about purchasing the piston drop in kit to solve the piston clearance issues, or is that not gonna be enough to solve this issue.
