09 Sportsman 850 Q:

Hello everyone. Today I’ve been in a situation… most the time I’ve been driving on Low speed+4×4, and I stuck in a mud… after I pulled atv out, I think I put machine on neutral/park [pretty sure , but it could stay on low?] , & I start playing with winch —> roll wire strait etc. after 5-10 min being there, the ATV starts running rough … Rpms were up and down, and "from zeit zu zeit" CEL was coming on and off.
What else – today morning after I start it up , RPMs were going from 1140 to 1210 up and down[temp. outside was around 38F] , then on the trail, when wormed up , it came back to normal 1180-1190 up to 1200rpms. 2 or 3 times died on me when put on gear and start drv. slowly. maybe to slow, not enough rpms? anyhow… after that mud I stuck – I’ve seen CEL once again and a last time… then 30min after I wrap it up and come back home and didn’t notice anything wrong. . . is there any way to check what was the code for that CEL ? even if it’s gone now ?

BTW. on time in the mud … the display showed that I had 1/2 of tank of fuel /
engine oil, coolant are fine. If not today, tomorrow grease job, then I’ll take it for a ride to see how it will run after one night in a garage. usually keep it in a shed. all advices and opinions are welcome . thanks .

tire weight

I am trying to find the tire weight of the stock tires on my 2014 550 touring. They are maxxis M9806. I am going to put on Kendra Bear Claw HTR’s and am trying to get an idea of the difference in tire weight. Thanks.

Pics from cylinderhead camshaft needed , engine rebuild…help needed :(

Hello,

for a few days i tested compression of my sportsman 500 efi.The compression was bad,around 7,5 bar , also 110 psi.
so i looked for motoroil…after removing the oil screw,i saw some metal filings on it…
so i demounted the engine…

my problem is,afer demounting cylinder head,i pulled out camshaft…but i did not see,how was the small spring build in..i mean the parts ,which are in cameshaft..the small shaft and the sping..i hope you can help…do you have some pics for me,how i must build in this parts?I think its the compression release,which i mean

also i need a dealer,for a rebuild kit…good gaskets,bearings and a piston oversize.

the first ,small, damage i found was a little damage on exhaust rocker….camshaft looks good….

a other question..the bearings from camshaft in cylinderhead have little scratches..you can see this ones but not feel…is this normal and so good?i mean ,this ones are not polished…

Thanks,
Thomas

Axles, Which Ones & From Where?

I soon plan to replace the "rear axles" in the 2005 Sportsman 400, as they have started to "click" from time to time when starting out in either forward or reverse motion.

Note: This machine does not get used hard, does not have large tires, nor does it have the power to twist off an axle….. so the heavy duty models aren’t required. :yaya:

With that said…. what would be the "BEST" and most "REASONABLY PRICED" OEM or Aftermarket axles I should go with?? :ditsch:

Please list brands and links to the best prices people have found…

THANKS!

2004 500ho

Hi all need some advice from you guys. I bought a 2004 500 ho as kind of a winter project bike turns over but will not fire. I have spark pulled the plug and checked that. Fuel going to carb and also in to the cylinder. She turns over great but just won’t fire up. Any thoughts?
Wondering if it could be a compression issue? Have to try and test this on the weekend if it could be
I’ve ordered a Clymer manual as I’ve got a 2001 500 ho too but I thought maybe someone else here may have had a similar issue.
Thanks in advance.

Question about idle 2004 sportsman 700 efi

Ok I bought it last week it has 1,736 miles 358 hours. I replaced the throttle body boot because it was dry rotted. When I first crank it cold start it it idles at 600 rpms and quickly goes up and fluctuates between 1000 -1050 rpms. Doesn’t seem right. What should it be idling at? Is there a way to adjust the idle on efi?
