JAGeSage Posted February 1, 2013 Report Posted February 1, 2013 I just picked up this 02 banshee, and since I've owned it it's been a pain to start and backfires when running but only out of the left pipe. Compression is good, good plugs and fuel.. What could this be? Carbs out of sync is my guess.. haven't had much time to mess with it, so I figured I'd ask here. Quote
JAGeSage Posted February 1, 2013 Author Report Posted February 1, 2013 Also another idea. But what leads me to believe out of sync carbs is just replaced throttle cable due to it breaking, thought I had em set right but was in a rush. thank you for the suggestion, I will rip into it this weekend.

Sandking Posted February 1, 2013 Report Posted February 1, 2013 Contact F.A.S.T their a cite sponsor and buy a carb sync tool its worth its weight in gold Quote
Jereme6655 Posted February 1, 2013 Report Posted February 1, 2013 /\ x2 I used to sync the carbs with using the eye sight technique. Then I got the sync tool from Jeff to make syncing all the toys easier on our lives (7 snowmobiles and 2 banshees up north). Talk about being way off and thinking it was close......wow. Either way it makes everything from setting the idle to mid throttle super super easy and exact. Quote
i ride 96 banshee Posted February 2, 2013 Report Posted February 2, 2013 check the chock tube between the carbs thats what happend to me you need to sync them and tune the carbs like the air screw and idle ect... did one side through more smoke than the other? Quote
JAGeSage Posted February 3, 2013 Author Report Posted February 3, 2013 Little more smoke out the roght carb, air is set right, gotta rip carbs apart anyway. Just changed throttle cable, havent hd time t rip into it, getting into it tomorrow. Stock air setting on those is 1.5 on mikunis if im not correct? Quote
JAGeSage Posted February 4, 2013 Author Report Posted February 4, 2013 Got the quad runnin, runnin 25 pilots, getting upped to bigger jets this week, wound up foulin right side, and runnin on one cylinder, gonna change plugs and try again. Will keep you informed. Quote
i ride 96 banshee Posted February 7, 2013 Report Posted February 7, 2013 running on one cylinder you should check your piston rings on that side .. Quote
HolySheet Posted February 7, 2013 Report Posted February 7, 2013 Compression test both sides and see if they match. Quote
JAGeSage Posted February 7, 2013 Author Report Posted February 7, 2013 I have same compression on both sides, rebuilding it soon, its at 115. I figured it all out, my coil is starting to go bad. Gonna do topend rebuild and freshen up bottom end as well. I planned on doing all my case seals along with a topend rebuild. Quote
Jereme6655 Posted February 7, 2013 Report Posted February 7, 2013 if your kicking over 115 then there is no need for a top end rebuild..... Quote
JAGeSage Posted February 8, 2013 Author Report Posted February 8, 2013 At what point would you recommend rebuild? Quote
blast off Posted February 8, 2013 Report Posted February 8, 2013 when it stops, then you build it bigger! just kidding, I did mine at 110 but some people may have different thoughts.................. Quote
