GB, I won't say you stole it from me, but down here Illinois Stock has been around since the late 70's. As long as the hood closes!

Back when I first met all you guys, nobody's machine was bone stock ! LOL... So much trash talking, until the radar gun runs started at the Pork Shack, that pretty much shut a few yappers up....
Ahhh, the emergence of the Pooslayer 500SS and unfortunately the fall from sleddingdom of a few Poo riders......whatever became of SkankyAl and Superdave?  or the Pope for that matter?

GB, replace that rear snowflap with this one. Off a RMK. It doesn't attach to the rear bumper like your current one, but use a strap around the bumper riveted to the flap. It keeps a lot more snow in the tunnel for cooling.

Good to know, thank you RD....  :thumbsupsmileyanim:

I did the first 2 seasons  2016-2017, I had the Indy6. Under the same condition they brought the temp down 30 degrees. They did ding the tunnel up a little though on the bottom edge where the tunnel/running boards meet. Last year just the longer snow flap and a Ski Doo inline stat in place of the Polaris in head stat. The Polaris cooling system on the 121 sleds is poor. It is totally senseless whatever engineer decided to not have cooling fins on the coolers. Longer tunnels like yours have longer coolers {still no fins though}, plus are used more in powder so cooling is better, but I would definitely do the flap ASAP if I were you and keep a eye on engine temp.

I purchased the flap, but I have not installed it yet (the sled's at my cabin).
I might back off on the scratchers for now, and just monitor the temps.

I assume they have idiot lights that warn you if the temps exceed "x" I know my REV would overhead every once in a while on hard pack and me running a 1.5" lug track.

not sure about your model, but my on my 2013 rmk you can select engine coolant temp instaed of MPH and monitor temps that way

GB, the owners manual tells you how to access engine temp on the gauge. There is a warning light also. 2nd warning light down from the top on left of gauge. I have been trying to upload pics but something wrong with the site.  You can download a owners manual here if you don't have one.  https://snowmobiles.polaris.com/en-us/owners-manuals/

RD, I have not installed the new flap yet. However I did manage to get around 400 miles on the machine last week, so now I do have some feedback to provide.

90% of the time, I was running at around 135-140 degrees, even on hard pack snow conditions. 
However, one day the temps got real hot out, riding above freezing and we had some rain, which made the snow turn to ice. On that particular day the machine got to 162 degrees. Still didn't get a warning light, but did stop a few times to cool down the tunnel. Trying real hard not to kill the machine during break in.

In addition, to being a dumb ass and not reading the owners manual (at all). I didn't realize until I rode 350 miles that I had not adjusted the computer to 91 octane gas. I had it set to non premium. So I did feel a slight HP boost that last 50 miles. Not really a boost, more like the sweet spot on the 2 stroke got lower into the RPM and I felt like the power came on quicker.

Regardless of the fuel, if you run in ethanol mode when the engine getting too warm, it will cool a little better because of added fuel and less timing.

This weekend was weird.... Saturday's ride had a tremendous amount of snow dust which made the Poo Poo run ice cold all day 125*F - 135*F (it might have helped that it was +5*F high). However on Sunday, the snow was much more hard pack and didn't seem to get kicked up nearly as much, even colder temps outside at 0F being the high and -5*F when we started out. Ran down a road for 3-4 miles and the sled got REALLY hot at 172*F.... kicked off in a few ditches to try to spin some soft snow up into the coolers and it cooled off down to 125*F within seconds.

Looks like I'm going to need to swap out those flaps and add some scratchers, as you recommended.....

Sleds got around 600 miles on it. She is a total blast to ride overall, but really really likes the deeper stuff on all aspects of riding. It climbs out of powder so nicely and tracks so much better on the trail when there is actual snow on the trail. Whereas it darts a bit when its total hard pack.

It shouldn't dart if you install dual carbides. Mine came with dual carbides on a single wear device.

Forgot to mention. 3 snowmobile related deaths on Lake Gogebic in the past three weeks. Some 50 year old lady hit rocks and logs along the shoreline at 2am the week between Christmas and New Years. Then this weekend, a mid 20's and 50 yr old man hit each other head on at a fast rate of speed killing them both - this happened at 7pm on Saturday. All three were drinking related.
