I just bought a 2019 Sportsman 850 sp, it’s awesome, love the power, sounds great, but when riding along Maintaining speed it seems quite loud from the riders position. This is my first “ twin “. Is this normal with the bigger bore engines. I’m used to my 570 which is much quieter.

Thanks

Here’s a few pictures of the up and coming mods I’m doing to the 17 sportsman 1000 hl. Mods are 33” bkt, highlifter lift kit, highlifter rear a arms, rvs performance clutch kit, front and rear frame braces, new belt, p3atv all new bushings, 4 new wheel bearings, new brake pads, front diff pinion plate, snorkel your atv risers. I might be forgetting some things and will update with pics as I do the work. I’m also splitting the transmission on a 16 ranger 900 crew and doing a turf delete and new input shaft.

It ran fine before I parked it for a few months, now it won't start. Its has spark, and getting fuel ( fresh fuel ). My only guess now is the valves need adjusted but I don't know what the clearance should be.

Removed the carb and cleaned the living bajebus outta it

Installed a new oring on seat under the float( needle seemed in great shape)
Reassembled and still getting the over leakin by (bottom line on the carb)

My question is does the line hanging lower then the carb cause it to siphon and does it have to be elevated to have the line above float level to create a float back pressure

How do you add pics to these post?
Lol

just bought a razor 800 and it will crank up and revs up by its self then dies.wont stay running.any ideas would be appreciated

I was thinking wheel spacers but the ones I bought do NOT fit the rear stock rims.
But I did find out, you can bolt them on and they fit properly backwards. Since tires are rotating only one way, they need to be moved to the other side to keep turning the same directionality,
the rears clear and my width is now 55 inches from tire edge to tire edge.
The front rims bolt on ok, but the tire air valve hits the brake caliper. So you would likely have to drill a hole on the other side of the rim.

I looked into trail width restrictions and it seems this is less of an issue today than earlier. where it was set to 50" max width.

The pic shows it mounted reversed, and it seats flat on the hub.

Yes I’ve picked up an old 2003 600 twin. It has sat up over 10 years. I have completely rebuilt it and it’s looking great and runs great except. At 35-40 with full throttle it stops increasing speed. You can hear it reving down but keeps running great at 40. Any ideas what to check next. Thanks

2437166 i have xcr polaris and need to find out the year can anyone help me sorry if this isnt atv im new too this and just need some help would be very much appreciated!!! Thanks everyone

When I shift into low gear it no longer shows the "L" or AWD symbol on the LCD screen. All other gears and info work. Wondering what causes this.

Hello,
I recently rebuilt the top end, started and ran on bench for total of 1/2 hour, it was basically for about 5 min till engine was good and warm then let it cool then repeated 3 more times for total of 20 min.

Everything seemed perfect.

Next day started it still on bench and it ran for 1 min. and then it died. Wouldnt restart. Pulled plug and soaked with water.
Pulled it apart again and put new headgasket on it. Back together and still wont run because of water in cylinder.
Pulled it apart again had head machined. New head gasket and then back together.

Started engine ran great for 1/2 hour in 5 min. increments
Came out next day and started it. Ran great for a min and then water in cylinder again.

I have drained the crankcase and got a little residual fuel out of it.
I drained countershaft and originally got some water out of it (assuming it accumulated from many river crossing over the years I have owned it and my ignorance in not knowing that this two stroke has engine oil in it to lube counter shaft bearings)

After starting I again drained both areas and have nothing in them of any significance. (of coursed it was only run for 30 min and so not much might have accumulated n that amount of time)

The pull start area has no water in it although before rebuild it did.(assuming that was also from river crossings)

Questions.

Could I be getting water into combustion chamber from leaking water pump seals?
Could my break in procedure be causing the problem? ( short multiple run times )
Should I have taken it off the bench and ran in for half hour in one shot under load instead of the multiple 5 min short runs that i did.
Thinking that maybe since i warmed engine up and cooled off multiple times wthout retorque on head as opposed to starting and running for half hour straight then letting engine cool and retorque that this might be the issue.

Any thoughts would sure be appreciated, I am about ready to make a boat anchor out of this thing.
