Spanks906 Posted May 25, 2014 Report Share Posted May 25, 2014 I rebuilt my motor last year with new crank, pistons, the works (no porting as the cash wasn't there). T5 pipes, tors delete and k&n filter with outerwears. I jetteted it fat to not burn it down, now with 6 gallons of gas through it and I feel the rings are properly seated. So I took my shee to a reputable tuner who did a good job on my raptor and a friend's kfx 400 since I didn't have time to tune it. Picked it up Friday, rode it at his place and ran awesome. Loaded it into my truck (fuel off) and drove the 8 miles home. Pull it out if the truck and it was running only on the left side. Take it back over, float was stuck apparently. Picked it today, rode great again. Put it back in my truck and drove home again. Take it out of the truck and it ran on both cylinders for 10-20 seconds then died like someone hit the kill switch. It wouldn't start so I pulled the plugs, shut the fuel off, killed the ignition, then proceeded to kick the shit out of it to clear it out. Then let it sit for 20-30 minutes in 70deg weather to help clear it out. Put plugs back in still nothing, doesn't even attempt to fire. Repeated the process but put new plugs in. Then kicked it. Nothing. Kicked it 15-20 times. Pulled the plugs and there was no fuel on them. Just a faint gasoline smell. It has fresh ethanol free premium (91 octane) mixed 40:1 with AmsOil Dominator. In the morning I plan to drain the bowls by standing her on end then try full choke and wide open to see what happens. I'm hoping someone with more knowledge will chime in. Thanks, Brad.

Spanks906 Posted May 25, 2014 Author Report Share Posted May 25, 2014 Forgot to say I ckecked spark while the plugs where out. Pushed it over by hand and looked, spark is good. Quote Link to comment Share on other sites More sharing options...
Spanks906 Posted June 4, 2014 Author Report Share Posted June 4, 2014 Seriously nobody has any idea where to start? Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted June 4, 2014 Report Share Posted June 4, 2014 Start by not standing it on end to drain bowls. Pull fuel line from carb open petcock, allow fuel to run for 30+ seconds to insure flow. I have a feeling when you are loading/unloading shit is coming lose and plugging carbs. I'd pull both bowls and look. Pull petcock check screen. Might need to clean tank out. Make sure vent hoses on carbs are clear and gas cap vent works and vent tube is clear.
