I just got this blaster and the first day I had it it ran perfect all day. Then the next day I went out to ride it and it started spitting and sputtering when it started to go into the powerband and wouldn't go anywhere. It sounded like it was getting too much gas so I checked it and it was fine. I cleaned the carburetor and everything and it still does it. The only thing I can think of is I have an exhaust leak. Could this be the problem? Or is there something else I need to check. I have checked everything I can think of and dont have anymore ideas. I would appreciate the help. thanks Brad

 

Will it get into the power, or does it just sputter right before and stay there?

 

If you had an exauhst leak it would probably run lean not rich. Could be the plug, which if it is the plug it probably needs jetted, coil,cdi..... Just start with the cheapest and easiest thing and work your way up.


by the way, do you still have the oil injection system working on that machine? If so get rid of it and mix your own before you blow it up

 

It just sputters right before and stays there. I changed the plug and checked the new one it is still good. Should I go ahead and get it jetted and see if that helps?

 

Oh and no the oil injection is blocked of I mix my own gas and mix it 32:1. thanks for the help so far I appreciate it.

 

is your plug black, like it is running rich? Did you hit any puddles with it? I had a problem with my 250 where the wires go into the stator cover I had water getting into the cover and it messes with the stator. And it doesnt take much water to mess with anything electrical.
