2025 Rumors

e start on a mountain sled drives me crazy. Especially on a 9r. The whole point of a 9r is the light weight rotational mass. Then you add a pound or whatever gear to the primary clutch?! Wtf? I guess if you’re a female with small arms or have a medical condition you gotta do what you gotta do. Pulling a rope as a mountain rider is not something I’m too concerned about.

Yep, just like how electric start on a dirt bike is a total waste, and that's why we only ride kick start motos in the hills.

Had the exact same thoughts until I accidentally snowchecked my 18 doo with shot. Haven’t gave it a second thought since. If it was still e start or rope I would have the rope in all of my sleds but a 2 pound penalty doesn’t phase me much. I guess if it did I could lay of the ice cream bars haha.

Shot doesn't work better. Estart you don't ever pull the rope. It is just another way to skin a cat. Definitely way lighter. They have also had their share of problems but Definitely fewer and farther between.

Shot has seemed far more reliable than batteries/estart from what I have seen

PTSD is still real from 90’s carburetor Summits.

Never had trouble with either but have had buddy's with shot problems.

I just called that skidoo arobics. Sometimes they just needed primed but you almost didn't dare without checking plugs. Triples were fine. I guess they weren't summits. Just the rotary motors you had to have two other guys to trade off with.

Not the same thing. I have e start on my woods bike too.

I’d have shot if I rode skidoo. Polaris adds weight to the primary for electric start. I don’t care about the battery weight. Rotating mass on sleds however is huge. It’s the whole point of the 9r. It’s why guys pay $800 to Patrick’s custom carbon to take off the same amount of weight on a primary clutch that the Polaris e start clutch puts back on.

99.9% of us are just amateurs out having fun in the woods with friends. Yes, if I was competing in RMSHA (especially for a living vs an expensive hobby) I'd reduce every gram of rotating weight. Skill and fitness play a far larger role than that extra 5% of clutch performance. Hell, look at the pros ride around on 650s alongside boost/turbo sleds for proof.

For me, with a bad shoulder, as an average middle aged desk jockey, I'll give up some performance for not pulling a cord dozens of times a ride. Glad we have options.

I have tried a lot of different clutch covers over the years. I had an indy specialty heavy cover he actually likes the heavy clutch cover for crank durability. I’ve ran stock and a carbon fiber cover also ran the ZRP lightweight cover and couldn’t feel a difference in performance with any of them.
The ZRP cover made the motor vibrate like crazy but I didn’t have it balanced after install. The carbon fiber cover and the heavy cover ran really smooth both were balanced. I think the carbon fiber cover might absorb some of the vibrations better than aluminum.

I have read that somewhere else too, however I don’t understand why DI is required if a Polaris motor is still able to reverse without it. I’m assuming its because the port injected fuel settles too quickly and needs the DI to give the engine something to burn after the sled has been sitting for a bit, but is there anything else?

A running 2 stroke can reverse without much trouble. They do this by slowing the engine, reversing ignition and advancing timing. For Shot to work, timing is really critical and high pressure direct injection over the piston is why the Doo starts in half a revolution. I imagine Polaris could attempt it with existing indirect low pressure injection but it would take several revolutions before it would fire, I don't know if the stator/mag/cap is capable of that. I know Polaris ran DI years ago in their jet skis but it had issues. I don't think patents are keeping Polaris away...

Exactly - Turcotte and his buddy riding those 650's with the turbo guys and keeping up! That was awesome! I have a couple not so great shoulders (and low back) as well and I would never go back to a pull start. And if I had my way and could afford it I would sell every sled I have and buy new ones to get the 7s display. My wife and I both have the 7s and we love it! Except Sunday when she couldn't find me or raise me on the radio and sent my nephew out looking for me. When I got back I reminded her she could see me on her display - she was like " oh yeah, I forgot about that! " Haha! So much for having tracking ability!

Cold start primes weren’t the issue if you knew what you were doing. But downhill parallel parking and roll over starts were new level.

 

[KootenayD]

roll over starts...

If you haven't wrapped something around your throttle and pulled the cord 40 times, have you really lived??

I would have been happy with 40 pulls and fire on those old POS’s

 

[duncan76]

If I had to roll mine over I always took out a cold one and buy the time it was done I'd only have to pull 10 times lol

I have rolled them and park downhill. Once in a while they just needed primed. Pulled and pulled and finally checked plugs and they were dry so primed it and fired right up. Once in a while, when stuck on hill, you just as well push to bottom of hill and level it out and then let the games begin.

My experience was 90% of the time they were flooded. 10% needing primed after a roll over.

I'm glad I'm not as old and decrepit as you two
