CrashRyan Posted May 22, 2013 Report Share Posted May 22, 2013 So im a new banshee rider and this is the deal. I took my shee out to the dunes for its maiden voyage and it had some small issues that we worked out pretty well we got it running solid and rode good for about 25 min or so when we decided to stop and take a breather. After the breather i could not get my shee running again and come to find out i had no spark. i have since then checked everything changed out the coil, bypassed the key switch, put a motor bike kill switch on my shee so i don't deal with the corrosion there, adjusted the pickup coil checked my stator, etc and now i have spark... but i dont have ignition so i kick the bike a few times and then i get a huge backfire off my pipes. it sounds like it wants to turn over but it just wont turn over. I was getting 180 on my compression test and i am running at a +5 timing right now but once i getting going i think it will move up from there where i am running high compression AV fuel. an thoughts our help would be of great help guys.

sheerider11 Posted May 22, 2013 Report Share Posted May 22, 2013 Pull the flywheel and check the key, shake the flywheel while its off. Pull the reeds, see if they split. Check the harness didn't melt on the pipes by the air box / under the seat Quote Link to comment Share on other sites More sharing options...

trickedcarbine Posted May 22, 2013 Report Share Posted May 22, 2013 Shaking the flywheel tells you if the magnets are bunk or not. Quote Link to comment Share on other sites More sharing options...
CrashRyan Posted May 22, 2013 Author Report Share Posted May 22, 2013 Shaking the flywheel tells you if the magnets are bunk or not. It's a new flywheel only the one ride but it is not an OEM flywheel any issue there? Quote Link to comment Share on other sites More sharing options...
Surfrjag Posted May 22, 2013 Report Share Posted May 22, 2013 Check slides are down, choke tube is in place, and bowls are on right carbs so choke works. What is compression? Flywheel should be ok they just come appart sometimes if not oem. Quote Link to comment Share on other sites More sharing options...
blue97shee Posted May 22, 2013 Report Share Posted May 22, 2013 what fuel are you running right now? at 180psi and +5 timing I doubt premium pump gas is cutting the mustard so to speak. Quote Link to comment Share on other sites More sharing options...
joey83 Posted May 22, 2013 Report Share Posted May 22, 2013 He said he had no spark... tors? Parking brake? cdi? Mine did same thing once and it was the cdi. get the clymers and start ohming pick up coil, coil, cdi, etc. Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted May 22, 2013 Report Share Posted May 22, 2013 like joey said....unplug your tors if they are still connected (and the brain box). cut the parking wires and make sure they can't touch anything. Check if your choke tube came out from between your carbs. do a leak down test. Shake your flywheel to listen for a sand type sound......if real sandy sound is hurt the magnets are busted. Find a friend with a shee and swap the cdi and if that doesn't work swap the flywheel........a lot of aftermarket electronics for these things are TERRIBLE.

Parking brake? cdi? Mine did same thing once and it was the cdi. get the clymers and start ohming pick up coil, coil, cdi, etc. I now have spark but it will not turn over i kick it a few times and now it backfires like a gun shot. is there to much timing for a plus 5 timing, and 180 PSI? Will timing cause a backfire effect? like joey said....unplug your tors if they are still connected (and the brain box). cut the parking wires and make sure they can't touch anything. Check if your choke tube came out from between your carbs. do a leak down test. Shake your flywheel to listen for a sand type sound......if real sandy sound is hurt the magnets are busted. Find a friend with a shee and swap the cdi and if that doesn't work swap the flywheel........a lot of aftermarket electronics for these things are TERRIBLE. tors are gone and the harness is now cut. I do have spark but is there such a thing as not having enough spark or a hot enough spark? im just not getting enough to ignite i get a backfire out my pipes. is that a pre or post detination?

coryv4 Posted May 22, 2013 Report Share Posted May 22, 2013 check the key switch wires make sure you have good grounds ect. this spring i kicked my ass off on my banshee because it had spark but wouldnt fire. come to find out it was the red an black key switch wire that wasnt making good contact(i removed the key and spliced the wires) and i kick it once it fired right up.

I already removed the key switch and the kill switch has been replaced. Quote Link to comment Share on other sites More sharing options...
joey83 Posted May 22, 2013 Report Share Posted May 22, 2013 Do you still have 180 on compression? You checked that after it quit running? Reeds ok? Squirt some fuel in carb and kick it. see if it starts. If it does its a fuel problem. Ive had plenty of bikes that had spark but still had ignition problems. Get the clymers and (or search for it) and check your cdi, coil, and pick up coil. Good luck 1 Quote Link to comment Share on other sites More sharing options...
