westtex_banshee Posted September 9, 2004 Report Posted September 9, 2004 1998 banshee with few mods. Was running perfect. Started sputtering. Left side cylinder is not firing. Can't figure it out. Last week replaced top end and yesterday replaced ignition coil. Have checked reeds and they appear OK (not sure what this means but when I removed reed cage, the intake port on right cylinder was moist and dry on left side. Could it be carb problem? Also, when I place my hand at the end of the silencer on right side you can feel heat - Nothing but a little amt of cold white smoke coming from left silencer...I'm lost and downtime hurts! Any help would be greatly appreciated Quote

Any help would be greatly appreciated Check the packing in your silencer on that side, It sounds funny but I have sceen the packing plug up the silencer and will allow a little exhaust to come through. Start there and work your way in. Quote
FasterTHENyou Posted September 9, 2004 Report Posted September 9, 2004 No, he has a fire problem. A dead cylinder can be caused by many things. switch your carbs around and see if the problem follows the carb. If it doesnt it is most likely an electrical problem, could even be your cdi Quote
westtex_banshee Posted September 9, 2004 Author Report Posted September 9, 2004 What exactly is the CDI? What does it do and where is it located? I replaced the ignition coil with no result. thanks Quote
FasterTHENyou Posted September 9, 2004 Report Posted September 9, 2004 The cdi is the brain of your ignition, it tells the coils when to fire based on the flywheel pickup. Switch the carbs around first and see if that is your problem, then check compression, then check electrical Quote
ledofthezep Posted September 9, 2004 Report Posted September 9, 2004 (edited) Sounds to me like a clogged left main. If they're stock carbs, I don't know that you can switch them around...I wouldn't anyway...plus your choke tube wouldn't connect. Never heard of switching stock carbs.

FasterTHENyou Posted September 9, 2004 Report Posted September 9, 2004 maybe im just a little too used to drag racing and not having to use the stock pos carbs? Quote

westtex_banshee Posted September 10, 2004 Author Report Posted September 10, 2004 Thanks for all the info. I'm spending tomorrow in the shop. I'll report tomorrow afternoon. Quote
westtex_banshee Posted September 10, 2004 Author Report Posted September 10, 2004 Shee is running again!!! Removed left carb and cleaned it up. Put it back together and both cylinders are firing. Still not running perfect. Loading up for some reason. Still in process of breaking in new top end. Maybe "loading up" problem will resolve once I can really put some gas thru it. Thanks for all your suggestions. Quote
