Banshee wont shut off

[Corndiddly5885]

Yesterday i was riding and my banshee started to blog and then i stop to check it out and it started to rev high. it soon pinned and i turn off the key and it didnt shut off or wen i hit the killo switch. what could be wrong with it

[fastquad02blaster]

It sounds like an air leak to me. I think that even with tors it would do this too. It could be a stuck slide also. I think that with a stuck slide it would shut off though. Anybody else?

If it gets too hot and you have carbon build up it can ignite the fuel mixture. Usually caused by an air leak or running too lean.

Check the crossover between the carbs.

i know its not running to lean. it could be a air leak. my compression is bad. 100 left side 122 right side. im taking the heads off tonite ill look around in there

might not be the trouble your haveing but when runing out of gas they will bog while riding and if you stop then idel up high just b4 they die. but as far as pined and not shuting off that might be from what was said above.

[Phelps]

did you check to see if it had gas? sounds like a lean rev from running out of fuel.

If you have an air leak it IS running lean. It may have been properly jetted before, but once an air leak develops it is getting more air and is running lean. Before you pull the head, I would do a leakdown test to see if you have any air leaks and then pull it down and do a topend job and fix any other problems you have.

i took the head off and it was running rich. i took off the cylinders and i have a bad ring on the left which was at 100 psi. i had plenty of gas in it around 1/4 tank. wen i get it fixed i will do a leak down test. before i torn it down i drove it like an hour and i didnt have the problem but its still bloging. the reeds didnt look the best. so you guys think by putting new reeds and reed spacers it might get rid of some of the blogging?

i dont see y low gas could keep it from not shuting off wen i hit the kill switch and turn off the key

It's called dieseling. Google it. It's usually more common in high compression motors, though.

alright thanks. anybody know about the reeds and reed spacers.

Happened on my jet ski its called a runaway.....you can yank the spark plug boots and it will still run...its running on the compression of the engine and is really lean......AIR LEAK......if it happens again while trying to solve your problem CHOKE IT OUT

Or put it in a high gear, and let out on the clutch, while holding the brakes.
