BeeCanBanshee Posted September 21, 2012 Report Share Posted September 21, 2012 So took my bike out the other day and was riding up and down some big hills then all of a sudden it starts backfiring and then stalled. I couldn't get it back running. So I got it home and replaced the spark plugs. And after about 10 kicks it started and idles. But is was pouring out blueish smoke. Then stalled after idling for about 5min. Then I got it started again but now it won't idle and back fires every now and then. And jerks at low speed. Pulled the carb and there's gas sitting on the lip of the intake boot. Checked reeds and they ate good. Mods are fmf fatties with pc II's, +4 timing, trinity 2to1 with a 33pwk 48 pilot 190 main dek needle on 3rd clip screw 1.5 turns out, k&n clamp on. Checked compression earlier this month and was 115 in both cyl. It's apart at the moment I'm waiting on reed gaskets. Any help would be great thanks.

BeeCanBanshee Posted September 22, 2012 Author Report Share Posted September 22, 2012 A little more info.. the last hill I was on while riding I was wot when it died out. It also fouled the plugs cause when I put the new ones in it ran better. Could the float level changed? Quote Link to comment Share on other sites More sharing options...
old put-put Posted September 22, 2012 Report Share Posted September 22, 2012 Sounds like your floats or needles may be sticking or have something inbetween the needle and seat? Pull carbs apart and check. Quote Link to comment Share on other sites More sharing options...
BeeCanBanshee Posted September 22, 2012 Author Report Share Posted September 22, 2012 Will do any more ideas Quote Link to comment Share on other sites More sharing options...
BeeCanBanshee Posted October 1, 2012 Author Report Share Posted October 1, 2012 So I swaped plugs and cleaned carbs, replaced intake boot and reed gaskets. Ran good for about 15 min then started backfiring and stalling again. Tested stator and it was good tested coil and I got .4 ohms on primary side and OL on secondary side. Which according to the manual is bad. Also had a plug cap with no continuity and my plug wires were a little rusty. So I got a new coil,wires and caps on the way. Will update again after I put the new stuff on. Quote Link to comment Share on other sites More sharing options...
BeeCanBanshee Posted October 7, 2012 Author Report Share Posted October 7, 2012 Well I replaced the coil,plug wires and caps and it runs amazing. Better than when I got it. Just wanted to update one last time so anyone searching can see the problem solved. Thanks for the help Quote Link to comment Share on other sites More sharing options...
