Hollister_Hitman Posted April 1, 2008 Report Share Posted April 1, 2008 I took my banshee out yesterday and it ran bad. It wouldn't get into the powerband. The last time I really rode my banshee was in early January. I think the gas in it is from December maybe November. I took the carb apart and cleaned it, it wasn't gunked or any thing. The spark plugs were awful so I put brand new ones in but no change. It started on the 3rd kick, idled fine but there is no top end. It kinda cuts out right where the powerband should be. I haven't touched the jetting, changed location, and there hasn't been a temp change really. I have had the same jetting in since October 2006 and it ran great all seasons. If the gas is stale would it cause this problem? What else should I check? Both pipes get hot so I am pretty sure it is running on both cylinders right? I have no time to look at it until Thursday. I am first going to buy some fresh gas and then take it from there...maybe I will check the spark on both sides and the compression Quote Link to comment Share on other sites More sharing options...
gregrob Posted April 1, 2008 Report Share Posted April 1, 2008 Maybe you have the parking brake on. Quote Link to comment Share on other sites More sharing options...
Hollister_Hitman Posted April 1, 2008 Author Report Share Posted April 1, 2008 Maybe you have the parking brake on. I thought about that cause I have done it before. I think when it runs on one cylinder though there is still a slight powerband. Thanks though Quote Link to comment Share on other sites More sharing options...
inthemail Posted April 1, 2008 Report Share Posted April 1, 2008 your a smart cookie i take it your warming up the ol bitch too right? Quote Link to comment Share on other sites More sharing options...
wacko2000 Posted April 1, 2008 Report Share Posted April 1, 2008 even though you cleaned the carbs out and they werent gunked up, I would def start by draining and changing the gas.. Cant hurt, I would run my bike if the gas was sitting for that long.. If you change the gas and the problem is still there, now you can look elsewhere.. just my .02cents Quote Link to comment Share on other sites More sharing options...
2001Stroker Posted April 1, 2008 Report Share Posted April 1, 2008 This might sound stupid, but it's not. Was it sitting in a shed where there's no heat? Or, outside? Was the gas tank full? When the temp drops at night, the gas and tank are at the "daytime" temp. That makes the tank condensate, causing water to build up in the tank. Always keep a full tank, if it is going to be sitting in an uncontrolled environment. Also, this new ethenol crap doesn't do to well when it sits. When it sits for a couple of months, it starts to go back to it's original state, CORN. It doesn't actually turn into corn, but it will gunk shit up. This just happened to my jet ski. I flushed the tank and lines, filled it with new fuel, and it ran like new. Take your fuel line off, and drain some in a clear container. Let it sit for about 30 minutes. If you can see water sitting on the bottom, drain the tank. Take it off, and make sure it is dry. Even if it doesn't have water in it, I would probably change it anyways.

monster_energy06 Posted April 1, 2008 Report Share Posted April 1, 2008 x2 on the gas chek.. also while yur there take off yur tank make it easier and also chek yur fuel on, off, res tap (pingle). the little filters on it might be clogged and dont let enough gas goo threw, but enough to run good on idle and low speeds Quote Link to comment Share on other sites More sharing options...

If you change the gas and the problem is still there, now you can look elsewhere.. just my .02cents Yeah I'm gonna do that first thanks! This might sound stupid, but it's not.

Even if it doesn't have water in it, I would probably change it anyways. It was in a cold garage. The gas tank is about 1/2 full. I will check for water thanks! I never thought about that or knew it could happen x2 on the gas chek.. also while yur there take off yur tank make it easier and also chek yur fuel on, off, res tap (pingle). the little filters on it might be clogged and dont let enough gas goo threw, but enough to run good on idle and low speeds It looked pretty good yesterday I have a clear gas hose but I will double check Quote Link to comment Share on other sites More sharing options...
Hollister_Hitman Posted April 3, 2008 Author Report Share Posted April 3, 2008 well I put fresh gas in out and it still ran like shit. Then I took the spark arrestor off to see if both cylinders were firing ( I have the dmc 916 exhaust). Exhaust was coming out of both so I rode it and it ran awesome!. I guess I need to clean my spark arrestor. IT is the disc type so I guess it got clogged and was choking the motor. Thanks for the ideas!
