Damn, they have that thing wound up tight at speed. The Doo is like its in another gear, like when the auto mfrs went from 3 speeds to 4speed overdrives back in the 80s. Sounds like theres something to be gained there in clutching or gearing depending on the motors torque output down lower.

Wow, that thing really rattled itself to death. Lucky you checked that before it sucked in too much air and burnt the pistons. Parts prices have gotten out of control, really have to look at aftermarket now for simple things like those gaskets. SPI must have those available, $50 per OEM gasket...

I saw your post elsewhere asking this, the only thing no one mentioned and I would add is to check all the driveline alignment. Make sure everything is turning smooth. Also I'm willing to bet Polaris has a very fat tune being those are newly released motors and they didnt want warranty issues...

I'm pretty sure those are just stamped steel halves welded together, the flanges are definitely welded on. It probably broke right at the factory weld for the flange connection to the pipe. You probably need to heat it with a torch first to burn off all the oil though so you get a cleaner weld.

Definitely running a bit rich. Given the age and mileage, I would start with running some injector cleaner mixed in the gas, they are probably a little dirty. I would also consider getting a set of VForce 3R reeds. I replaced the ones in my 13 and the stock ones were nothing great, known to be...

If you are still looking I just recently found that Saddlemen is making replacement covers for the older sleds. Dennis Kirk and several people on ebay are selling them.

Yeah, i thought I remember my 00 700 being closer to 2 turns. The reeds should help clean up the low end stumble as well, I never put them in the 700 because they were problematic with failures back when i was playing with tuning that sled. I've seen alot of talk on the mikuni conversion as...

I wouldn't worry about the front wheels as much, you can even see in your pic that the rubber wheel pushes down more on the track. The bigger problem is that the rear wheels are an entire different assembly to raise the wheel centerline, that explains the upright support with the HRP logo. So...

Keep in mind the screw is an air screw on the Keihins, completely opposite of the fuel screw on Mikunis. Sounds like it needs more air. The vforces tend to run a little wonky at idle until they have a chance to break in too. My buddy has had one of those sleds since it was brand new, it was...

Judging by this symbol machined into the supports, its an old Holz racing setup. Doesn't appear they are around anymore. I agree that you should swap it all back to something with rubber as the bare aluminum is just going to wear the track. Hard to say whats different about them vs the stock...

I'd be willing to bet thats a misprint, the 2 XC models are probably the same and the Adventure is the one with the different spring. Call the dealer and see if they can look up the preload spec in their online service manuals from the factory, chapter 1 in the manual gives all the specs for...

There's a link to the AXYS service manual here... https://polarisstarpower.com/threads/general-tech-faq.226/ They recommend removing the duct and moving the oil reservoir out of the way and going in from the side.

I've never changed one on a 600 but you are probably going to at least have to take that fiber duct part of the airbox that overhangs the plugs to get better access.

Its the brass one screwed into the side of the head, has a 90deg brass nipple right next to it. The black one bolted in underneath the head is the knock sensor.
