Straiter Posted December 28, 2009 Report Share Posted December 28, 2009 I have a 96 Banshee that fails to run on both cylinders. I completely hard wired the entire bike to eliminate some other problems, and still no good. I swapped out the CDI, the Coil, and plugs. I even swapped out the coils wires from one side to the other. I removed the carbs, cleaned, and then reinstalled. I am getting spark to both plugs. When i pulled them out, the cylinder that was firing is good and the other that wasnt was wet with gas. I know it is getting gas. The side that isnt running is the carb with the choke on it. (Left) Any ideas or suggestions? Quote Link to comment Share on other sites More sharing options...

sleeper06 Posted December 28, 2009 Report Share Posted December 28, 2009 When you try everything and it all checks out with the ohm meter try swapping the fly wheel,I have seen alot of shit go wrong but twice in ten years I had flywheel throw me 4 a loop for days,checking and rechecking,shake it if it sounds like loose rocks,or pick-up isnt rite,magnets come loose.Give it a whirl Quote Link to comment Share on other sites More sharing options...
Grason Posted December 30, 2009 Report Share Posted December 30, 2009 mine is doing the same thing cept my right cylinder is not firing. to me i believe its a fuel issue because i have good spark from both plugs (gapped at .040) and i have 125lbs of compression from the l.h.cyl ( the one that works) and 135lbs out of the right cyl ( the one that wont fire). I had the bike runnig last night, it would sit there and idle no problem with out the little tube connected that goes between the choke ports or whatever. the left pipe did have a good bit of white smoke coming out of it like it was loading up......so i got a piece of hose and put it between the carbs for the choke and now it wont sit there and idle with out hitting the gas and still no fire from the right cylinder, is there some stupid im missing or do i need another set of carbs or maybe something with the reeds, i just duno. any help would be appreciated, thanks Grason Quote Link to comment Share on other sites More sharing options...

fastbanshee8 Posted January 4, 2010 Report Share Posted January 4, 2010 (edited) Have you checked the gap on your pick up coil, by the flywheel? It's supposed to be gapped at .020. If it's not, then it can cause firing issues. While you're at it, you might as well replace the spark plug boots, as they are cheap, and easy to change. They just screw onto the ends of the plug wires. Edited January 4, 2010 by fastbanshee8 Quote Link to comment Share on other sites More sharing options...
Fullthrottle02 Posted January 4, 2010 Report Share Posted January 4, 2010 Have you checked compression, didn't see it listed in your post? You have spark and you have fuel. When you swapped plug wires, did the problem stayed with that cylinder or move to other? Quote Link to comment Share on other sites More sharing options...
Straiter Posted January 7, 2010 Author Report Share Posted January 7, 2010 Have you checked compression, didn't see it listed in your post? You have spark and you have fuel. When you swapped plug wires, did the problem stayed with that cylinder or move to other? So, I was able to get a new flywheel for my bike, replaced it, and still the same problem exists. When out at superstition, the problem remained. The only differenct this time is that after messing with it and finally putting back to where it was at normally, it started running on the left cylinder for a couple minutes and then went back to the right. This is really throwing me for a loop. Ive got the fastest bike of all my friends, when it runs. I spent new years riding someone elses when I got the chance. Im about two minutes from putting it in the shop!!!! Quote Link to comment Share on other sites More sharing options...
bhatch21 Posted January 7, 2010 Report Share Posted January 7, 2010 When you cleaned the carbs, did you look at the reeds? Maybe the one on the left side is cracked or not closing. Quote Link to comment Share on other sites More sharing options...
fastbanshee8 Posted January 7, 2010 Report Share Posted January 7, 2010 I'm guessing that you still haven't checked the pickup coil gap, or changed out the spark plug boots? Do the simple easiest things first, and then proceed on, if none of them fix it. Quote Link to comment Share on other sites More sharing options...
No Limit Powersports Posted January 7, 2010 Report Share Posted January 7, 2010 If its only hitting on one side and you changed plug wires and the problem did not change sides its most likely a fuel issue. If you have stock carbs make sure the choke tube is in place, make sure that you have the right bowl on the right carb there is a difference. If Unlikely that its ignition related if its only affecting one side but be sure and check the pickup gap at the flywheel should be about .020, and make sure the tors is disabled.

TwistedSheeRida Posted January 7, 2010 Report Share Posted January 7, 2010 Could it be possible that your floats are getting stuck? Quote Link to comment Share on other sites More sharing options...
bp12 Posted January 8, 2010 Report Share Posted January 8, 2010 i just ran into same problem and i opened up my top end to see what could be going on after syncing my carbs over and over and discovered a shattered piston ring and a cracked reed and after more inspection found a stripped out water impeller gear who knows cant hurt to go through it Quote Link to comment Share on other sites More sharing options...
