There should be a plug under and forward of the console around the gas tank filler. It maybe in a bag in there if I remember correctly. The tether plugs right in.

850(840) settling in 169 170 hp. On bmp dyno. 167.6 so far on dtr dyno 173 plus pulling some fuel. Seems like we should have good power on tap.

I’m pretty sure 850s are hitting my now. At least Indy xc

I’m not familiar what a dragon saver kit is. Can you elaborate.

For once Polaris has finally gave the engine some much needed transfer port and there is meat left on the bone to do some porting. It’s my understanding that the cyl walls are thick enough to support a substantial big bore also. I think this engine has not only good stock performance but has...

The clutch pullers have specific applications . They are about 30 bucks. Flywheel pullers are generally run of the mill and a few different designs work fine. Not the claw type.

Send the crank out to a pro for rod installation and truing. If it was just end bearings I’d say have at it. But you really want a pro to rebuild the crank. Then just put it back together yourself if you feel up to task. If your gonna do basic stuff yourself you will need a clutch puller for...

I didn’t get a shipped email either but mine was shipped on sept 27th .

This engine is making very good power and the engineers are saying the bottom end has been built to last the long haul. They seem very confident that it’s gonna prove to be very reliable. With this power and more on tap with a lil tweaking some good clutching and the efficient skid in chassis...

so as of now it's a go ! With recent snowfall there appears to be enough white stuff to greenlight some Polaris test rides . This fri and sat in addition to new models inside there will be 2018 models availible for test rides. Bring a helmet and gear. Waiver must be signed and no alcohol prior...

Puller, compression tool (bought or made) to change secondary springs ,not needed for helix changes. That's pretty much it for weight ,primary and secondary springs and helix.if you want to disassemble the primary you will need a holding fixture and spider nut socket with a big breaker bar...

I ordered a black / black tunnel /raw spindles and rails. The coated spindles on my other ones get a lil banged up from ice chunks and saplings so I said screw it I'll save the money and keep em AL. Like my xcr . "850" under the hood and cobra track which I keep second guessing. Last 2 years...

No I have not. I don't have Facebook. But Friday I'll be looking hard at the cutaway engine.

No doubt this is gonna sell sleds this year for Polaris.

I ordered up a tripple black 850 (837 ?) Indy 129 looking forward to trying it out........... and destroying my lawn nxt fall.

Lenn did you have an opportunity to discuss the movement of cyl bolts to accomadate better transfer ports. If so did the engineers frame the talk as the transfers were adaquate or di they say they are plenty big or something like that. I'm hoping for Big transfers or a lot of extra meat in cyl...

Awsome line up great job Polaris. Oh btw 129-850 class

My guess. 129 conventional tunnel (maybe a 137 option but I doubt it) 840 twin. 168-172 hp. 850 doo killer. Doo had the fastest 850 class sled when they had the only 850 class sled. They are about to have the second fastest sled in the 850(840) class. Oh and a 1.5 storm track option.

Put the stock can back on before you go crazy and see what happens with temps and performance. Then leave stock can on and a new belt (if it's not) with proper belt deflection set. After some miles you will need to reset deflection. Or it Will be super loose.

Your right on the 600 doo being a decent value sled. The 850 thing idk about that I've seen (like anything else ) faster ones AND slower ones. I believe that shipped has now sailed for doo. They had the fastest 850 class sled when they were the only one. I'm pretty sure that's about to change on...
