RX1 shorty over heating!

[Dukester]

I ran with a guy, who rode a shorty with an M10, who had over heating on hard pack trails. Was that common on shorties in general?

Sketr, My light came on once last year. We were running a ice packed road with minimal lube. I think it is fairly common, but only when the conditions are poor. I pulled over, turned sled off and packed the exchangers with snow. I waited about 20 Min before I fired it back up. Never saw the light since then. When I got into similar conditions, I would make it a point to steer off the road and get as much loose snow as possible...BBY

Hey Sketr2 & BBY- The light comes on at 210 F, and won't hurt it at all. I come down the return lane at 210, the light comes on, and when I shut it off, it is 225-230. No problems yet, and compression and power still feel good. But Matt is right, find some loose stuff right away, and you can keep going on your way.

Also another easy trick to do if you're going down a trail that doesn't have a lot of snow getting thrown up onto the heat exchangers is to drag your feet on the trail (but make sure you're not going WFO) and this will kick snow dust up onto the exchangers. Also the M-10 doesn't kick up as much snow dust as a regular Yamaha suspension, that could be the reason for the overheating too.

Ran one last August until the light came on...no sign of coolant overflow, it wasn't even high in the bottle.
On a hardpack trail in winter, both sled's lights came on about the same time...was riding with my daughter (first time out for her solo) about 20 mph for 20 minutes or so..we put some snow on the footboards, but I knew it wasn't a problem.
If you are on hardpack, ride fast, if you can. Our normal crew let's no grass grow under a sled, and we rode a bare road for 4 miles and no light. No more scags either, but didn't like the stock ones anyway. :twisted:
That track can blow a lot of air on the front exchanger if you're moving fast enough.....

mine was overheating a lot of time at wide open with snow and with hardpack . so i put a srx exchanger in the back and no more problem . thebest.

Never had the RX-1 light come on once last season. Viper light came on a couple of times on the same trails. Once was a warm day and the other was a perfect trail. Never heard another RX-1 owner talking about over heating problems.

Well it happened to me twice last year. Once was when I had stored it indoors overnight in Hearst (Canada) and took it out in the morning when it was super cold. Riding down a loooong railway bed averaging about 80Mph and the light came on....coolant spewed all under the machine... :shock: I looked at the exchanger and there was about 2" of ice packed onto it...I knoked all the ice off and I never saw any thing again. I think it may have had happened due to the fact I came from a warm moist enviroment to a cold one very quickly...the other time it happed I was doing about 15-20 Mph for about 10-15 minutes. I don't think those big CC motors like the slow rides.

In 3200 miles last year mine came on twice in one day. The temp was about 10 degrees outside. There wasn't any ice build up but the trails were as hard as a rock. Just a couple of dips off trail and it went off.

Rode 4k miles last winter, Lite came on once from a blown heat exchanger from a blown track due to studs. My dad had a m-10 and he Overheated all the time Untill he installed a flap that was 2in longer then it never overheated again. That was the trrick for his. Polaris adress a problem with sleds equiped with m-10 had peoblems with overheating and to install a longer flap or more heat exchanger in the rear.
