edgecummins5.9 Posted March 10, 2013 Report Share Posted March 10, 2013 I just got this banshee about 2 months ago it's stock except toomey T5's. It ran great till this week.. It starts up with no problem and runs good buts it randomly cuts out and dies almost like if you hit the kill switch but sometimes it will catch it self and keep running. It doesn't happen when accelerating or cruising, mainly when trying to take off or rev it up to spin it around in my driveway or on a trail. I put new plugs in and disconnected the TORS. But it still does it. Im not sure where to start looking for the problem? Any help would be appreciated. -Adam Quote Link to comment Share on other sites More sharing options...
JAGeSage Posted March 10, 2013 Report Share Posted March 10, 2013 What do your plugs look like? are they black and fouling? I'm almost leaning towards a semi blocked pilot jet. Or a misadjusted air setting. Quote Link to comment Share on other sites More sharing options...
edgecummins5.9 Posted March 10, 2013 Author Report Share Posted March 10, 2013 The one was a little darker than the other.. Currently the jetting is 280 mains 25 pilots 3rd clip pos. On stage 3 dyno jet kit and 1 1/2 turns out on the air screws. Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted March 10, 2013 Report Share Posted March 10, 2013 clean the carbs, sync them, then make sure you unplugged the tors brain box and disconnect the parking brake Quote Link to comment Share on other sites More sharing options...
edgecummins5.9 Posted March 10, 2013 Author Report Share Posted March 10, 2013 Cleaned the carbs and put new pilots in just for the hell of it and still no change. Still cutting out when I slide the clutch to spin the quad around or take off. Quote Link to comment Share on other sites More sharing options...
JAGeSage Posted March 11, 2013 Report Share Posted March 11, 2013 Is there hesitation when you immediately crack on the throttle? Old gas by chance? Did you put 25s back in? Id be running 27.5s if it were me. What alt are you at and how about temps. Quote Link to comment Share on other sites More sharing options...
JAGeSage Posted March 11, 2013 Report Share Posted March 11, 2013 And also as Jereme said, is the parking brake still connected? if so, eliminate that, see if it fixes it. Quote Link to comment Share on other sites More sharing options...
edgecummins5.9 Posted March 11, 2013 Author Report Share Posted March 11, 2013 Jagesage: Parking brake assembly I deleted already. It revs fine if I crack it with the clutch pulled in. Gas is fresh mixed with castor 927 @ 40:1.. Pilots are 25's. altitude is about 750ft temps are about 45-50* Quote Link to comment Share on other sites More sharing options...
edgecummins5.9 Posted March 11, 2013 Author Report Share Posted March 11, 2013 It's just when I rev it to take off or spin it around it feels like the ignition is being turned on and off rapidly. But it's not constant. I rode it for about 30 minutes yesterday before it happened. Then it did it about 5 times within a half mile tight trail.. Once it gets on the powerband it pulls nice and hard with no hiccups or anything. Quote Link to comment Share on other sites More sharing options...
edgecummins5.9 Posted March 13, 2013 Author Report Share Posted March 13, 2013 Well I turned my air screws in 1/8th turn and it seems ok. I rode it around quick and it didn't seem to act up. It just takes like 20 kicks to start it now? Possibly stock reeds are just about wore out? Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted March 13, 2013 Report Share Posted March 13, 2013 pilots.....go up on them. aftermarket pipes, and stock pilots create a lean situation down low.......when the clutch is pulled in or the bike is in neutral....it will rev fine. This is because there is no load on the motor. But put it in gear and try and leave....depending on how much you've revved it and a bunch of other variable......it starves on take of. Try putting in LARGER pilots......not new 25 pilots. Quote Link to comment Share on other sites More sharing options...
edgecummins5.9 Posted March 13, 2013 Author Report Share Posted March 13, 2013 Yea I'm going to get 27.5 pilots and put those in along with a TORS eliminator kit and probably a set of v force 4's for good measure. Quote Link to comment Share on other sites More sharing options...
