    Rk tek head

    I'm running 13:1 on my '12 with RKTek pistons to match. I've ran 50/50 100LL (av gas), 100% 100LL, and straight premium from Shell. I've got to say that I don't think running 100LL has any benifet. I've had no detonation with straight pump fuel. Also, the sled runs hotter with RKTek parts in...

    Pro Rmk

    If you're coming from an Etec, I think you're just noticing the difference in motors. I've talked to a few guys who have said the Etec's power is almost 4-stroke-ish in its smooth even power, where the Polaris motor is "old school" two stroke feeling of hit you hard in the beginning, then turn...

    Handlebar Risers for 2012 Pro RMK

    I've got a 2" Rox Riser. I'm pretty impressed with it, hasn't moved under normal circumstances, yet in a nasty situation they have moved enough to save damaging me or the machine. I wouldn't hesitate to buy a 3" Rox if I needed more.

    Bearing behind top belt drive sprocket

    can anyone tell me, does the upper and lower bearing cross with industry standard bearing #6205? That is the bearing used in the 2011-12 models. I'm trying to see if I can retrofit and improve the factory system to put on my 2011 Assault Rmk...

    Top End Bog

    What are your guys' running temps when these bogs are happening? I've been researching a lot about this and it seems that the Polaris computing has a "safe" system that takes action as temps near 130 degrees. It begins to limit your WOT runs and seems to cause a "bog" condition. I rode 138...

    13 pro not back shifting

    Snobyrd...What did you use for a thermostat housing gasket after you removed the thermostat? I'm going to do this mod pretty quick...as well as new EV solenoid. I'm suspecting that my injectors are fritzing also, seems that most guys with '11's have already replaced blue injectors with Yellow...

    So, who's switching snowmobile brands next season?

    I'm thinking about it. Ride a 2011 RMK Assault, its got 2700 miles on it, new motor this winter. Was hoping Polaris would have done something with their 800 motor for 2014, but since they didn't, will be doing one of two things, 1) buy a new M8000 162, haven't had an Arctic Cat since the early...

    13 pro not back shifting

    I have the 13:1 head. My temps don't change from Sask (1600') riding to BC riding (5000-8000'). i also run 50/50 Av gas (100LL) and premium. I was wondering if RKTek's placement of the temp probe is causing the temp to read differently. Polaris has it in the center of the head, RKTek is in...

    13 pro not back shifting

    Results from the shop was the ecu had two old codes stored, an exhaust temp fault and throttle stuck fault (using the tech comments wording here). Also the TPS was out of spec and throttle cable wasn't at the proper tension. I'm going to try going for a rip this evening in our minimalist snow...

    13 pro not back shifting

    any updates from anyone? Last night I unplugged the exhaust valve hoses from the solenoid and plugged them so it works "old school" on exhaust pressure and not by solenoid. It ran awesome. I'm still looking for a few hundred more RPM as per RKTek specs on the motor after rebuilding using his...

    RMK Assault Questions??????

    I have an '11, love the CHASSIS. Compared to my buddies old Rev Chassis summit, it handles like a dream. I haven't rode much else to compare other than a 2011 renegade backcountry which I didn't like. We have our Assault ski stance at the narrow setting, but I believe it's still a little...

    Blown top end 2011 pro rmk 800

    RKTek. I did pistons and a high compression head for less than some of the other "fix kit" things out there...RkTek drop in pistons are less than $400, the head is another $400...

    2014 release rumors

    The only thing they "need" to do is build a 160hp (at the track) bullit proof motor. The chassis is awesome in my opinion, and they don't need to do any goofy flexing to make it handle sweet. We should be more educated in a week or so...

    Dealer warranty problems ...

    That is pathetic. Isn't Backus Racing in the Sicamous/Mara area? We met those boys at the Saskatoon Snowmobile show, seemed like a good group of guys.

    13 pro not back shifting

    Weird...this is exactly what my sled was doing... I hope you get it figured. I have my primary fixed now, but there isn't enough snow or slope to test it in the same scenario as the mountains... If its the TPS, I'd sure like to get it looked at before next wednesday. I don't have any idle...
