    To add a BOV or not, a bit of boost run-on

    So, I've been doing some tweaking with the idle speed. -idle speed was low on cold startup when I installed the turbo, so I had adjusted it up a little. -now I lowered it back down, which seems to have helped a lot with the run-on. Idle is @ about 1100 - 1200 cold, once warmed up it's @ 1650...

    Well, my Silber kit certainly does not have a BOV. Does not look like those pics. Must be an older kit?

    To add a BOV or not, a bit of boost run-on

    Yeah I'll talk to Silber, but they don't use or sell bov's for 2 stroke kits. Someone somewhere has bov'd a silber polaris I figure lol. I'm capable of drilling / tapping for the vac nipple, hoping someone has a setup to share for the rest.

    To add a BOV or not, a bit of boost run-on

    I don't think thats whats happening but I could be wrong. Is this a thing with turbo kits? I would expect the spring in the TB's to be plenty

    850 water pump failure

    With the engine still installed I could get the wp cover off, but I don't think it would be possible to work on seals. Maybe with the mounts un-bolted and tip the engine back? at that time your so close to just pulling the engine.

    It can't cost people money to tow / help someone off the mountain or they'll be less likely to help again (friend of not)

    850 water pump failure

    -To update the bearing, the cases would need to be machined for the ring so that wasn't gonna happen. -Not a sled mechanic, but previously was an auto mechanic. I have also been working on my own sleds and dirt bikes since I was a kid. Most of my testing is outlined in the service manual. My...

    To add a BOV or not, a bit of boost run-on

    Installed a Silber kit on my 2019 Axys 850 @7psi. Running great, loving my first turbo sled! There's a moment of "run-on" coming off boost. Not an issue at all in deep snow, but can be annoying from time to time on higher traction. The held rpm seems to be linked to boost left in the system, as...

    850 water pump failure

    I tested the oil injectors over and over again. -all 5 external injectors "pop" at 4psi, close at 3psi. In factory spec. -the internal water pump cavity injector (that relieves to crankcase) pops at 2psi, closes at 1psi. I did not replace it with the updated screen covered injector because it...

    Foot rest replacement help

    Got the job done, kinda miserable. -ground down heads of rivets on the inside of the tunnel, or on the side of the footrest being replaced to minimize cosmetic damage. -large upper Huck rivet replaced with one of the rivets available from skidoo. Same ones that attach the footrest to tunnel...

    850 water pump failure

    Got the cases split and tested the check valves. All the external checks pop at about 4.5psi, and close at about 3psi. Very consistent. The internal check that relieves from the water pump cavity is free flowing, so then I pull out the new replacement that is an updated screen covered unit on it...

    850 water pump failure

    Somewhere around 3000km total. -At about 800km my center cavity oil line popped off, dealer warranty partial rebuild (oil check valves, pistons, all bearings and seals). They said the internal oil check valve was not relieving from the water pump cavity. -This fall I installed a new top end with...

    Foot rest replacement help

    Hey Doo guys! A little help please. My friends sled was damaged in the process of towing my Polaris off a mountain (go ahead and poke lol). I want to make it right for him. Has anyone replaced the footrest piece, and / or "roller link" on a G4? I have concerns about some of the hardware. -The...

    850 water pump failure

    The gear on the water pump shaft is plastic for sure. I got it as torn down as I can for now. Waiting on a flywheel puller along with the rest of the parts. It def got hot but I was nice to it as I could be. Pistons, bearing etc all look ok so far. I can't get the water pump shaft to come out...

    850 water pump failure

    Sad time for my sled and my season. Had a strange overheating issue, and an exhausting tow /extraction on the weekend. Was hoping thermostat, but I found the water pump not spinning with the engine. Must have ate up the plastic teeth. Engine coming out, I'll learn as I go. Not new to this kind...

    Knee pads

    Ive been riding with Leatt 3DF Hybrid's for a couple seasons, love them! Very comfy and they stay put. This coming from a guy who wears full knee braces all summer on my dirt bike. Leatt quality is very high.

    Turbo coolant burping

    This morning I confirmed I had all the coolant hoses (turbo /intercooler kits) connected correctly. Still not getting warm hoses (from the PTO side head port to the coolant bottle is all cold while the large engine hoses and tunnel is hot) Still stumped.

    Hey guys Looking for some advice! I'm finishing a Silber kit install with their belly intercooler setup on my 19 850RMK. I don't seem to be getting any flow to the coolant hoses at the turbo. With the engine running and warm on the tunnel, main engine hoses, and bottle: -not feeling any warmth...
