I have this 650 Prowler. It will turn over but will not stay crank. I have to keep priming it for it to stay crank. Once u get off the gas it will go dead. Also, the tailpipe and muffler turned cherry red while running. I put in a new spark plug and change gas with fresh gas. Has anyone experience this problem? I need some help.

I would say give your carburetor a thorough cleaning. If it runs with the pedal down, your main jet is clean & your idle jet must be plugged. Your idle jet takes over when you let off of the throttle. I have the same machine. Has it sat for any lengths of time?

Yes, it has been sitting for awhile. But what makes the muffler turn cherry red while trying to keep it running??

I'm guessing it's probably running lean. Lean running conditions will make the muffler turn red hot. Give your air filter & check & while your at it check your antifreeze.

The air filter and the housing is pretty dirty. I will try to get to cleaning carb tomorrow and let you know afterward. I appreaciate the input.

Your welcome. Good luck with the cleaning, just take your time and do everything right the first time. It's a lot easier than doing it twice :)

As suggested, your carb probably needs cleaning, and clean the air filter good and the box also. Also check to see if yours has a square black panel, about 4"X 6" back of the frame where the back of the seat sets. If so take this small panel off and (one on each side) and I think you will find a air filter there also. I am not sure if the 650 has it but the 700 does. (or mine does) I had a 650 and I dont remember seeing it, so look.

I have cleaned the carb out but it is still turning the tailpipe red. I cleaned the air filter and the housing out.

I am going to ask a dumb question. I assume you have checked the water and does the fan kick on?

Does this have any mods? Did you put in a jet kit? When was the last time you did a valve adjustment (if the manual states it requires one as standard maintenance procedures). I hear of this happening when someone puts a new jet in that allows too much fuel. Also make sure your exhaust is not clogged.

Does the plug look okay?
