My build may start sooner than expected. I was out riding today and my raptor started cutting out and died. I looked down and smoke was coming from underneath the seat. I took the seat off and cranked the motor. White smoke is coming from the breather hose that was originally connected to the airbox lid before i took it off. What do you think? It only blows smoke while cranking the engine.

 

Come on people, need some info

 

Just your compression and Spark plug. Sounds like its rings or the Piston........ Let us know what you find out.

 

oh and another thing, my coolant level is way over full, almost to the lid, dont know if that would indicate anything. I just dont really want to tear it down if its relatively something simple.

 

Pull the plug and see if you smell any antifreeze on it.... Also the white smoke maybe burnt antifreeze. Check your oil level and color also.

 

I'm guessing that ATV engines aren't far from car engines so I'll put this in. On a car when you get white smoke it usually means you are burning antifreeze. Check the oil and the plugs to see if it smells or looks not right. You probably didn't run it long at all so you didn't burn any antifreeze hense the reason why your coolant tank is about full.

MIke.

 

First thing i did was check the oil level, the oil on the dipstick looked normal but wasnt a real good indication, any more possibilities?

Thanks a lot for the info!!!!

 

Did you pull the plug?

 

Not yet raptorowner, Im in graduate school through the week, it will be this weekend before ill be able to look at it. THanks a lot!

 

Bad head gasket is a possibility.
