98_banshee Posted November 10, 2012 Report Share Posted November 10, 2012 The other day I was letting my banshee idle and it was running fine and then the idle got really low and only the right cylinder was firing the left was blowing cool air out of the pipe. So I switched the plug wires and then the left cylinder started firing and the right was doing the same as the left before. I switched out my coil with an extra one I had and its doings the same. I tested the coil and it's getting spark. Brand new plugs in the bike. So today I took off the carbs and cleaned them. They were fine. It won't idle at all. Someone please help I'm getting really frustrated. Reeds are also fine. Only thing I could think of is a weak spark or something coming from the stator.

stand er up Posted November 10, 2012 Report Share Posted November 10, 2012 Bad plug wires/caps? Quote Link to comment Share on other sites More sharing options...
98_banshee Posted November 10, 2012 Author Report Share Posted November 10, 2012 I don't think so, I'm new to most of this two stroke stuff. I also heard it could be a bad crank case seal? I'm stumped I have no idea what to do. Quote Link to comment Share on other sites More sharing options...

Check all your connections keep it simple at first Quote Link to comment Share on other sites More sharing options...
n2otoofast4u Posted November 10, 2012 Report Share Posted November 10, 2012 Pull the plugs and have someone kick the bike over while you watch the plugs and see if both have spark... Then report back Quote Link to comment Share on other sites More sharing options...
98_banshee Posted November 10, 2012 Author Report Share Posted November 10, 2012 N2o that's what I did, and sheeeider if it was a bad cdi wouldn't the bike not start at all? And I'm leaning toward the stator. It has compression I also pulled the head and pistons look fine. Thanks for the help guys hope I get it figured out soon.

n2otoofast4u Posted November 10, 2012 Report Share Posted November 10, 2012 Next pull the stator cover and pull the flywheel. Make sure it hasnt spit the key out of it. Quote Link to comment Share on other sites More sharing options...
fat_tony Posted November 10, 2012 Report Share Posted November 10, 2012 (edited) if u have a volt meter set it to ohms and check resistance of plug wires i bet they will be different....in a wasted spark ignition if resistance to 1 plug if different than the others it can then start misfireing on the other cylender...i think it will fire the lower resstance route every time iirc .....maybe somebody who knows more than me will chime in soon for ya...also if plugs have different resistance that can affect it but i just noticed that u said u tried a different coil so now im not sure but its and easy check Edited November 10, 2012 by fat_tony Quote Link to comment Share on other sites More sharing options...
98_banshee Posted November 11, 2012 Author Report Share Posted November 11, 2012 It's nothing wrong with the coil, I'm gonna put my keystart back on and see if I has to do with that. I think it has to do with the fly wheel gap and the key inside the flywheel. I'm gonna go figure her out and get back to y'all Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted November 11, 2012 Report Share Posted November 11, 2012 think simple. if you can switch the wires and the problem moves with the wire then there is an ignition problem....so that means its not the carbs or the pistons/head. DOUBT it would be a crank seal as if it blew a crank seal it would start sucking the tranny fluid and you would see it start smoking extra hard off of the right cylinder. before you go having a panic attack try either trimming or replacing your plug wires. AND your plugs. even though you said they're new who says its not a bad plug. i've personally had an issue like that.....new plug ran like shit.....pulled them out to discover one had been dropped and cracked the porcelin insulator....caused it to arc to the threads instead of the electrode. after you have exhausted the small easy items then start moving up to larger items like stator and what not.

This is IMHO the perfect way to attack a problem this is ignition related since it changed when you swapped plug wires. Very good advice and a systematic approach. Bravo!!!

98_banshee Posted November 11, 2012 Author Report Share Posted November 11, 2012 Alright thanks guys, I'll keep you guys posted with what's going on Quote Link to comment Share on other sites More sharing options...
98_banshee Posted November 12, 2012 Author Report Share Posted November 12, 2012 well today i took apart my harness and found out one of my connections came loose so i plugged it back in. it was the white/red wire which runs from your cdi to your magneto. i then tried to kick the bike over and it still wont start. i know your not supposed to spray starting fluid in a 2 stroke but i sprayed a little in it anyway. it started up and ran for about 5 seconds. which now makes me think its a pilot jet clogged up or something clogged up inside the carb. anybody else have a input on the matter, any suggestions???????

Jereme6655 Posted November 12, 2012 Report Share Posted November 12, 2012 Did you make sure you put your choke tube back inbetween the carbs? Quote Link to comment Share on other sites More sharing options...
