I have a 2006 SP 800 and it has been great for about 500 miles. No problems until today when I was riding up in the hills in some snow I heard something that sounded like my belt was falling apart so I stopped and let it sit for a while and then headed back down before my belt was completly gone but now it was engaging fine however it still didn't seem to be running right so I stopped and check the oil and as soon as I pulled the dipstick out it was like exhast was coming out of the quad. Could it be gas in the oil? The other odd thing is that weather the quad is warmed up or cooled down(when I got home) it starts doing this right away? Any ideas what would cause this? Should I change the oil or just wait until tomorrow and take it to the dealer? It still has full power and the belt seems fine. Thanks in advance for the help.

MIGHT BE WRONG BUT SOUNDS TO ME LIKE YOU ARE GETTING COMPRESSION IN CRANK-BROKEN RING MAYBE??

 

If I understand you correctly, you mean you removed the dipstick to check the oil and saw some steam escaping the tube?

If that's the case (NO PRESSURE should release), that is normal, especially in cold temperatures. It's just normal evaporation of condensation in the crankcase. That is the reason auto manufacturers recommend changing oil more frequently during cold weather & short trips. The engine, in that case, does not have time to warm up enough to evaporate all the condesation.

Steam is normal (small amount lingering in tube). As long as your oil level is correct & there is no pressure inside the crankcase, your all set.

I would try to describe the noise you heard a bit better though, so everyone can help you. May have just been a stick or branch hidden in the snow that made all the racket.

 

If it is normal to have some steam escaping from the oil dipstick hole would this taper off at anytime? It really isn't steam escaping though, it seems to me more like exhast. I just started it up again after it had been sitting for a few hours it is still doing it and if I run it without the oil dipstick it sounds like there is some slight clanking and cluncking sounds coming from it.
To describe the sound i orginal heard when riding a bit better it sounded just like when pieces of your belt are flying off and slaming into the belt housing. I cant think of any other way to explain it than that.

 

Yeah, if you run the engine without the dipstick in you'll hear all kinds of noises AND you'll get vapor coming out. That crank is whipping around in there about 18 times / second @ idle, and the downward motion of the piston is going to generate pressure.

I didn't realize you did this with it running! [img]i/expressions/face-icon-small-happy.gif[/img] I'm surprised you didn't get a faceful of oil!!

As for the noise, it's a shot in the dark trying to diagnose from a computer screen. All I have is guesses. Maybe some small rocks got kicked up? If it sounds ok now, and you've checked out the belt & clutches & the inside of the cover for debris, I wouldn't worry too much about it.

Keep an ear on it though, and good luck!

 

Smitty,

Thanks for the help I think it should be fine but I will keep a close eye on it.

 

Sounds like Smitty got you squared away on your problem, so now lets move on to something more a little happier. Where are you that you have snow in Sept.? I AM JEALOUS[img]i/expressions/face-icon-small-wink.gif[/img]

 

I live in south central Montana (Billings) and about 40 miles south of Billings in the Pryor Mountains there is already about 3 feet of snow. It was really tough riding because it was hard packed and really difted.

damn, 3 feet. lol. you make sure you keep it all right over there, i dont want any of it if i could help it.
