sheerider11 Posted December 4, 2012 Report Share Posted December 4, 2012 My girlfriends banshee has been getting harder and harder to start. We went out yesterday bike was kicking ass all day, no problems. We went back to the truck to fuel up and then no start. I was leaning towards the reeds the whole time giving me the problem. Now today when I got home from work I started to mess around, still no start. I pulled the reeds they look good. Still gonna get new ones but they sealed for the most part. I pulled the stator cover and flywheel and stator look good. I plug in my inline spark checker and the bike sputters with one plug out and the in line checker in. either side. It sometimes back fires when I kick it too like the timing is off. I'm gonna go back to the garage and take the coil off my bike first and start from there. Any ideas appreciated thanks just for shits SS/port 21 cc domes stock carbs no tors no parking brake fmf fatty 25/280 one up from middle on needle oem flywheel and stator Quote Link to comment Share on other sites More sharing options...
Nightmare Posted December 4, 2012 Report Share Posted December 4, 2012 Compression maybe Quote Link to comment Share on other sites More sharing options...

sheerider11 Posted December 4, 2012 Author Report Share Posted December 4, 2012 its like the timing is all out of whack. I put on my cdi and coil and still nothing alright its either the stator, or in the harness. threw her cdi and coil on my bike and it fired right up. Has anyone had anything related to something like this and where about to take a look? Also does anyone have the picture of the drag harness so i can start eliminating wires?

sheerider11 Posted December 4, 2012 Author Report Share Posted December 4, 2012 Alright I checked the resistance on the stator, that was in spec. On Wednesday I'm still gonna swap between my bike and hers. I hope it comes down to the harness, at that point I'm just gonna swap the whole thing Quote Link to comment Share on other sites More sharing options...
WINDYCITYJOHN400 Posted December 4, 2012 Report Share Posted December 4, 2012 Flywheel spun on the crank maybe...... Or try fresh gas. One of the guys in our group bought some premium 93 octane and it was junk after a week. (with the economy....who knows how long the premium is sitting in the ground. I'm sure the regular sells faster.) His bike ran fine once we push started him. That would be an easy test and an even easier fix. Quote Link to comment Share on other sites More sharing options...

The I pulled the flywheel twice and the key was fine and I got it back on every time no problem Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted December 4, 2012 Report Share Posted December 4, 2012 weather change? it get colder where you are? reason i ask is that your fmf pipes and stock 25 pilot jet dont really match each other. 95% of the time the fmf pipes like 27.5 pilot jets....so your already lean on the pilot circuit which has alot to do with start up. Add in some colder weather and itll be running that much more lean. did you do the compression test AFTER these problems started or are you going off of readings that you took when/if you rebuild the bike before it started fighting? also have you tried something simple like new plugs? dont mean to offend you.......seen it happen before though. my riding buddy usually lets his wife ride his bike once a year........EVERY single time she rides it......it stalls and she cant get it to restart. same routine every time.....he walks down the road and kicks his heart out and sees nothing happen.......i walk down with 2 new plugs and a plug wrench and its the 2nd kick and its running. we chalk it up to her lugging the motor so hard that she is carbon/oil fouling the plugs to where they'll "run" as long as the bikes running......but no chance for a re-start Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted December 4, 2012 Author Report Share Posted December 4, 2012 Yeah new plugs. I had 27.5 pilots and the bike smoked a lot and would bog off the line and down low. Threw the 25 in and raised the needle richer and it runs good and plugs look good. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted December 4, 2012 Author Report Share Posted December 4, 2012 I'm gonna pull the top end. I pulled the head and when I spun the motor I think i heard sloshing. So now I think that the crankcase may be full of gas. has anyone had this problem?? Quote Link to comment Share on other sites More sharing options...

Jereme6655 Posted December 6, 2012 Report Share Posted December 6, 2012 i think there was someone on here a while back that had an issue like that......where his carb floats got stuck and instead of coming out the overflow hoses, it filled his cylinders.....

AKheathen Posted December 7, 2012 Report Share Posted December 7, 2012 yes, it's real common on sno-go, or at least used to be. had the case and pipe on my ski-doo as full as you can get it. same thing, and got lucky not hydro-locking. stock carbs should over-flow, though, before spilling into the engine. water in the pipes is not un-heard-of. pull the plugs and have someone kick it fast repeatedly. if fuel is in there, it should be shooting out in 3 kicks. also, how about the plug caps, and engine/frame grounds?
