*Update*2001 Rmk 800 needs a few problems addressed

[PolarisGuy97]

Ok guys. I'm getting fed up with this sled. I fixed all of the issues it had, fixed the brake line, tightened the track ect. I went to take it out for the first time today. And it ran just fine up until it warmed up. Then it would only run if the choke was on half. Then I figured out why the aHole who sold me this sled didn't extend the brake line. Because the brakes lock up. So I was just about to the truck when i was at around 7-8k rpm and only going 30. Stop once I got back to the truck. Smelled something burning so I opened the good and the chaincase oil dipstick was on fire. So I got that out in a hurry. But I'm so frustrated with this sled I'm about to just say F it and part it out. Anyone have ideas? Let me know please.

Could be the water temp sensor, if it doesn't run well when warm. Never heard of the dipstick catching fire, that is really hot.

 

[PolarisGuy97]

Maybe. How is a water sensor affecting how it runs? Can't be anything carb related? Also the track keeps making a ratcheting noise.

 

[rdr99]

If the sensor thinks the motor is running too hot, it goes into limp mode. If you had to run with the choke half on, then there might be an air leak somewhere making it run lean. Are you sure it is the track that is ratcheting? If the track is tight, then it might be the drive chain in the chaincase, could also be a bad driveshaft bearing.

with the dipstick burning I have my guess figured..

 

[PolarisGuy97]

I'll post a pic of the burnt dipstick tomorrow. And the limp mode makes sense because if it wasn't on choke right when it gets to 4k rpms when the clutch engages it wants to die. I guess I kinda forced it to run with the half choke.

you sure somethin didnt just get sucked into a pilot jet and clogged it, and maybe you overtightened track which caused way to much friction, and your hyfax were melting too, wanting to stop the track? lol, no disrepect, we just see that a lot with newbies running on hardpack round here.

I just cleaned the carbs right before I tried to take it out. And when I stopped right at the truck the last 10 feet it made a whining noise like the brake was on.

 

[PolarisGuy97]

Ok I just went to look at it this morning. I smelled a strong odor of gas. It was coming from my sled. So I'm gonna have to check the carbs again. It was leaking right out of the bottom. Like before. Must have something to do with those tubes under the carb bowls.

 

[PolarisGuy97]

Is there a way to test the sensor?

 

[tom999p]

Haha, my brake locked up too, it sucked... I also bought another sled that had a melted dipstick, it turned out that the previous owner drove 20 miles with the parking brake on!

 

[PolarisGuy97]

Ok. So I went to start it today. Went to give it a nice hearty pull. Well it would not pull. So I was concerned thinking it was seized. Well I pulled the plugs and tried giving it a pull. I swear I've never seen so much gas come out of cylinders like that before. It must have some sort of carb issue. Any ideas?

bad needle/seat.

Fuel filled cylinders

Could be bad vacuum fuel pump.

Stuck float valve?
