Cottondoc Posted August 25, 2013 Report Share Posted August 25, 2013 I have a 2006 banshee that is stock other than CPI pipes and 28mm Keihins bored to 30mm. This is how I bought the quad. I have had it about 9 months. It has always ran good without any problems until this weekend. I ran the quad for about 30 minutes on Friday. I ran it relatively hard, and it ran fine as always on Friday afternoon. The gas in it had been in the tank for a couple months, and it had Stabil in it also. I topped off the fuel tank on Saturday morning with what I thought was the same batch of premix. It was supposed to be 93 octane pump gas with Klotz Techniplate at 32:1. Again, it ran fine the day before on this same gas. Saturday the bike didn't seem to smoke at all after it got warm, but it smoked some on Friday even after being warm. After running it about 5 minutes on Saturday it began to idle really high and act kind of unusual, so I immediately shut it down. I'm beginning to think the fuel I added on Saturday must not have been premix. I drained the tank and refilled it with fresh premix I ran the quad again, and this time it did smoke a little(the same amount I thought it smoked Friday). But, it continues to idle high, something it never did before Saturday. It runs fine otherwise, and has its normal power. But it continues to idle really high. Any ideas? If I ran it without premix, I know it would have damaged the rings and bearings, but why would it still be idling high? Thanks for any info or help.

toytech Posted August 26, 2013 Report Share Posted August 26, 2013 check you slides and cables to make sure they are not sticking. or possible atr leak. did the air filter get wet? Quote Link to comment Share on other sites More sharing options...
SOUTHTHIRTY Posted August 26, 2013 Report Share Posted August 26, 2013 Leak down test Quote Link to comment Share on other sites More sharing options...
Cottondoc Posted August 27, 2013 Author Report Share Posted August 27, 2013 The air filter didn't get wet. It may be the throttle cable and slides. Unfortunately I had to leave the quad at my parents house. I had to get it out of the garage, so I had to leave it at my parents house a 4 hour drive away. Would running it with a leaner mixture likely make the slides stick? What about the leakdown test? Would running it with a leaner mixture hurt the rings and make it idle high? Again, thanks for any help and info. Quote Link to comment Share on other sites More sharing options...
J-Madd Posted August 27, 2013 Report Share Posted August 27, 2013 Leak down test. Probably intake gasket or cracked boot. Worse case crank seal. Or carb out of sync. Check that first. Quote Link to comment Share on other sites More sharing options...

mike0chek Posted August 28, 2013 Report Share Posted August 28, 2013 def do a leak test before riding it any longer. Quote Link to comment Share on other sites More sharing options...
99 shee Posted August 28, 2013 Report Share Posted August 28, 2013 Agreed do a leak test...also if you have a tors removal check the idle screws are tight as well as your air screw..they could get loose. Quote Link to comment Share on other sites More sharing options...
Cottondoc Posted January 8, 2014 Author Report Share Posted January 8, 2014 I know this is an old thread, but I just solved this problem. I re-learned the lesson to not forget the simple stuff. My Banshee had been idling high and it just started out of the blue a couple months ago when I first posted this thread. I never could figure it out, so I took it to a friend's shop. He figured it out in less than 30 seconds while I was still telling him the story of how it started. The throttle cable at the thumb throttle assembly had somehow tightened up on its on. I guess through vibration. Anyway, the thumb throttle had no play at all. He loosened this and gave it about a 1/4 inch or less of free play and it instantly solved the problem. As you can see from the quote below, toytech said to check this in the first reply to my question. This site is great for help like this. I did actually call my self checking the throttle cable, but I guess checking it isn't much good if you don't know how it should be. When it didn't stick, I assumed it was good. Anyway, got it straight now and just wanted to update the thread. Thanks for everyone's help and time. check you slides and cables to make sure they are not sticking. or possible atr leak. did the air filter get wet?
