Handyman Posted April 12, 2006 Report Posted April 12, 2006 Well I just talked to the Yamaha shop I have taken my banshee to since the left cylinder stopped firing again and I was tired of messing with it. They said they have ran every diagnostic check on the damn thing they can think of and can't find the problem. The have ran it up and down the street and have duplicated the problem. The manager said when I was explaing the problem he didn't believe me at first but now does. He said there is no air leak. he said it's as if the left cylinder was turned off with a key. he has called in all his most experienced mechanics to try to find the problem and they have been working on it all day. From what I am told they should find the problem either today or tomorrow(hopefully) because all they have left is the carbs and a couple small things left. The manager said that even though they have been working on it for 3 days all they are charging me at this point is $65. He said he has never seen anything like this before in his 17 years as a yamaha mechanic. Quote
. Posted April 12, 2006 Report Posted April 12, 2006 is it an intermittant problem or is it happening all the time and when it happens it continues to happen? Switching the plug wires will tell you if its coming from the plugs to the cdi yamaha dealerships tend to not know much about banshees...... if its happening at all times is your choke tube connected? Quote
NYUK Posted April 12, 2006 Report Posted April 12, 2006 switch plug wires, i would look at the coil. pull the spark plug boots and trim the wires back a quarter inch. put the boots back on and try again. Quote

The choke tube is new and was clamped on at one point with 2 hose clamps and there was still no change. Quote
PUSH THE THROTTLE Posted April 12, 2006 Report Posted April 12, 2006 If there's no change with the wire swap. It really only leaves plug, carb, and possibly the reeds. Put new plugs in, clean and sync the carbs, and take a look at the reeds. Quote

Cotton eyed Joe Posted April 12, 2006 Report Posted April 12, 2006 switch plug wires, i would look at the coil. pull the spark plug boots and trim the wires back a quarter inch. put the boots back on and try again. 501099[/snapback] I agree. With a 2 stroke engine (the dealer may or may not know this) you will have 1. Ignition and 2. Carburation. If it isn't the carburators (and it infact IS NOT an air leak) it will be ignition. Thats all there is. No valve train, no real fancy electronics. Another thing the dealer might not know is that the coil fires BOTH cylinders at once. So, its not your cdi, its not your stator, its not your rear sprocket. If one side gets spark, and the other doesn't....start there. Quote
Handyman Posted April 12, 2006 Author Report Posted April 12, 2006 I haven't talked to the mechanics since this morning...I will be calling in a few to see if they will trim the wires back a little. Quote
Wicked98Shee Posted April 13, 2006 Report Posted April 13, 2006 (edited) break out the KY cause ur gonna need it by the time the stealership's done. find a friend with a banshee and talk em outta thier coil, swap em and try it. cause if ur carbs are positively clean and your reeds are in good shape and there is good compression .... that only leaves one area left ..... ignition .... do like nyuk said and trim ur wires back to get a better connection Edited April 13, 2006 by Wicked98Shee Quote
rocketboy Posted April 13, 2006 Report Posted April 13, 2006 (edited) poor jetting is usually noit intermittent if they are sealed correctly ,it sounds electrical to me like the others have suspected ,i think you have a poor spark from wires coil stator or cdi ,are the pickups clean on the flywheel and staor plate ? Edited April 13, 2006 by rocketboy Quote
race-a-holic Posted April 13, 2006 Report Posted April 13, 2006 Might have nothing to do with it,but have they done a compression check yet?Might have one cylinder on it's way out(loosing compression/bad rings). Quote
GleasmJA Posted April 13, 2006 Report Posted April 13, 2006 I see that your post says TORS eliminator kit. Did you remove all related crap, or just remove the carb tops? If you didn't remove all the crap, then maybe that is a problem area too. Just a thought if you haven't removed all the rest of the stuff. But i would guess that if you have got the kit that you removed the rest of it also. But i would agree too. If your reeds are brand new.. carbs have been cleaned several times... sounds like electrical somewhere.....nothing like chasing a good electrical problem to ruin your day. Sorry.... keep us posted what the problem is or was when fixed. Quote
98bonerSTOCKshee Posted April 13, 2006 Report Posted April 13, 2006 trim the plug wires back yet? 501184[/snapback] If he switched the wires around and it didn't change the dead cylinder to the other side I don't think this would help... but still do it anyway... Have you actually looked at the plugs while kicking it over to see if there was fire? ( Just making sure) Make sure both plugs are out or shee'll fire up on 1 cylinder. Fuck the stealership you got the HQ! Quote
lethal Posted April 13, 2006 Report Posted April 13, 2006 I had this same problem.chased it for about a month.I had put a ricky stator on and the gap was to much between the fly wheel and the pick up.I closed it up and shee ran fine.try that. Quote
