Sportsman 500 HO Problem After Engine Heats Up

I am having an issue with my 2010 Sportsman 500 HO. It starts and idles fine. it runs perfect until the engine heats up. Then, it cuts out, loses power at full throttle. If I back off the throttle it will run ok until I go to full throttle again. I have replaced the fuel filter, air filter, spark plug and rubber boot that goes from the air box to the carburetor. I have ran some sea form through it. No change with any of these. Anyone else experiencing this or have an idea of what could be causing this? There is no white or black smoke when this happens. After it cools off, it will run fine then start acting up again.

Thanks in advance!

Fuel controller?

I have a 2011 can am outlander 650 max xt. It runs pretty hot and from what I read a fuel controller will help this. I don’t want an exhaust because this is my hunting quad and I want it quiet.

So my question is am I able to just add a fuel controller? If so which is the good one to get?

Thanks!

Spark Plugs – 1995 TRX300FW / 1987 TRX350D

Hey guys,

Just wondering about the spark plugs for these bikes. Has there been a preferred plug over the years?

My buddy needs to change the plug on his 350 and while we’re down at the dealer I’ll get myself a new one and a spare one for my 300.

I checked on the parts list and I have a couple choices:
SPARK PLUG (DPR7EA-9) (NGK)
SPARK PLUG (DPR8EA-9) (NGK)
SPARK PLUG (DPR9EA-9) (NGK)

SPARK PLUG (X22EPR-U9) (DENSO)
SPARK PLUG (X24EPR-U9) (DENSO)
SPARK PLUG (X27EPR-U9) (DENSO)

What’s the difference?
Thanks!

16 Outty EPI or Dalton clutch kit?

My secondary bolt backed out on my 1000 Outty and recked my clutch cover and spring… Wanna throw a clutch kit on while I have it apart. Anyone have any recommendation what to go with? Bike is all stock, still needs to be very drivable at low speeds just looking for a little more low-mid range without high engagement. My rpm right now is kinda all over the place to and usually 2-300 rpm to low. Is a clutch kit worth it or just stay with stock?

Any help would be great, I have had a full STM 6 setup on it that I had on my Maverick as well but I have had a lot of trouble with them so I took them off cause I need it to be reliable. also didn’t really like how they acted for everyday slow riding and noise made.

How fast can you go in awd?

I have a friend who has a stock 350 raptor and he seems to think its faster than the 570 lol. That being said I know the 570 isnt a race bike or anything but I know its faster than that bike in AWD or not. I was wondering can I lunch the bike in AWD all the way to top speed? I know some other 4×4 bikes say not to pass a certain speed when the 4×4 is on.
