Rebuilding the 13' Pro....same problems.

[Old Scud-doo]

So I decided after being one of the 15% 2011-2012 owners in the reliability thread and having 1300 miles on my 2013, I was a just asking for issues. I am going down for shoulder surgery on Friday and decided it would be a good present for me to do my PT if my sled was fresh and waiting for me this spring.

Before you flame me, this sled is completely stock!!!! Only clutching and torque arm added. So after discussing my options with my dealer I decided to do the MTN TEK reliability kit instead of going back to OEM. Hope I choose wisely.

My dealer found that the rings were already chipping and flaking and there was considerable blow by evidence on the pistons. This is the same exact problem my 2011 had when it had 1100 miles on it. I believe the piston and rings to be the weakest part of these sleds. Maybe I should be happy I got almost 2 seasons out of it but any of you who haven't had a catastrophic failure and have over 1000 miles, you just haven't checked your rings. I don't believe these sleds have pistons and rings that will last much past that.

Not asking PI to pay for it or do anything. Just wanted you all to do know that even if you don't notice it at the moment, your rings are probably already coming apart. Be pro-active and freshen up that top end. Gone are the days of consistently getting 3 to 5k out of a motor.

I got 1250 out of my 13. Crank seal let go and I lost PTO bearing. Not sure if anything happened to top end previous to that...I'd like to get a report on how the top end looked.

Under warranty, so just waiting for a new engine.

Scott, I would definitely have the dealer check your rings on the old motor just to see if they were starting to go. Give you an idea on when to rebuild the new motor if nothing else.

Probably sounding like a broken record here Old Doo. Follow the ring flaking and fix the port chamfers before reassembly. Heat cycle those MNKT pistons. If you decide to go with any other head make sure you check the squish correctly.

GEO: Hoping my dealer did all that or does all that before I pick it up tomorrow. I know for a fact that he as going to heat cycle the motor a few times for me today since I asked specifically that he does it.

I just passed 1000 miles on my 11 last weekend 850 of that boosted after the season its going to indydan for a LRTM and all the love he can give it. With only 1k on the chassis it will get me through a couple more seasons if the engine is solid

bottom end stuff is scary but i got 2 years warranty cause i would rather be sledding with a aftermarket fix kit in if i get over the 1000 mile mark than it blown sitting at the stealership for a month. i got till December 2016 for the bottom end to go.

also turned my oiler up, i burnt 5L in a week of riding at cooke city... the same as a 600 carb doo in the group, and double the etecs. Thinking my 14 is well lubed.

He told me there is a pretty deep scuff in one cylinder.
I'll see if I can look at them when I pick up my sled on Friday.

1000 Miles???!!! That thing is wore out polzy!!!

what can I say two sub par winters and an injury shortened season keeps the mileage down

Your going to love your LRTM!

I had 3200 miles on my 11 and it didn't have any flaking. Rings, pistons and cylinder were perfect
