Sportsman 450 Won’t Idle Cold

Hey everyone. I have a 2006 Sportsman 450 that will not idle well when cold. Choke doesn't seem to help much. Just have to sit and hold the throttle until it warms up enough to shift it. Tried changing idle speed screw but then it idles too high once warmed up. I will note that I've seen it smoke some oil burning off when you start it up after letting it sit once in a while. I used to have a UNI on it, but now switched back to stock.

Just curious where to start. Could the oil smoke be related? Valves out of adjustment or low compression? I do admit I didn't clean the UNI as much as I should have, and is why I switched back to stock. Also had the valves checked probably 80 hours ago by my dealer. They did not adjust at that time.

Or is it in the carb somewhere? The wheeler doesn't get run a ton as it's up north, so I guess I wouldn't be surprised either if it's a fuel issue.

Issues starting my 2007 450

Replaced the battery this year and the issue I'm having is after riding around for an hour or so and then stopping the machine won't start again. Nothing on the display. Lights won't come on etc... If i let it sit for 30 minutes or so it will start back up and I can start and stop it maybe 10 times and then it will happen again. Usually at the most importune place. A few times the engine has completely shut down while riding but this is jot usually the case. I've checked the harness where the wires connect to the ignition and it seems fine. It sure wher else to check .. Not terribly mechanically inclined but won't be able to get it to a mechanic for at least a week so I was just seeing if there's something I might be able to check my self.. Thanks!

DWW new member, 800 EFI issue

2006 Sportsman 800 EFI quits running after ~1 hr, wait an hour runs and repeats issue.
How do I check pump pressure or an electrical issue (component opening up when heated up).

Hello everyone I’m new here from northern MN

Hi everybody I'm 47 and disabled. I havnt been able to work for the last 4 yrs. I walk real slow with 2 canes. I'm going to Mayo next week to hopefully get some answers. I have had 1 back surgery and 2 on my neck with no improvement. I spend a lot of my time driving around in my side x side. I like to putts around in my shop on little projects that i can do at my own pace. That is what brings me here. I need some info from all you smart bombardier people. I am working on my dads 05 John Deere Trail Buck 500 Auto. Im try to remove the primary drive clutch. I have been reading in many forums on the net and people are all over the place on this. Im not familiar with this clutch. Im trying to remove it as the spring is hanging up and it wont stop. This clutch is different from comet ac and polaris where you can remove the outer cover to remove the spring. I need to know if this is a split clutch that I can just remove the outer shiv and spider or does it come off in one piece like all the clutches im used to? I have read where some say both ways. I have the JD part number for the puller JDG 11200 I cant seem to find one to buy. I dont really want to spend $60-$100 on a tool im just going use once. Could some one please tell me how this clutch comes apart?? If someone has one of these pullers could you please give accurate dimensions of it so I can build one of my own. I need to know what thread is in the clutch so I can get a bolt to screw in against the proper round stock to pop the clutch off. I know a guy that works at Team Industrys where the clutch was most likely built that will turn me out apuler too. I just need all of the accurate dimensions of the tool. Please HELP

Xmr coolant smell?

16 xmr r, is anyone getting a coolant smell? Looks like I'm getting a minor drip here and there out of my overflow hose. Coolant is at recommended level. Is this normal?
