Anyone have this happen. Bike shot 6" of flame out exhaust while idoling. Kept riding it and eventually it quit. Bike wasn't running too good slight miss than bad miss at 6500 rpm than run good and fire quit.

 

Did you have your fuel pet **** open while parked? Maybe one cylinder was slightly saturated (not enough to hydraulic) Ran crappy until it cleared. Dunno

 

Well a flame like that definately would been the result of gas building without iginition, then BOOM! Ignition. Plug might have fouled or there is a spark problem seems to me. But with all those mods...who knows. Definately seen quite a few faulty Dyna's around here.

 

I had the flames constant for about a 1/2 hour at all speeds, it was idoling fast, inside of pipe glowing red and blue flame like a torch, miss was slight on bottom ,then got bad in mid, then come out of it, would pull hard up to 70, then climb to 75.

 

Thanks for the replys, I think either cdi or attac messing with the jetting. cdi is only suppose to go to 32 or 33* and keep the same all the way thru. I tried opening cover on air box slightly, low was worse and high speed was same.

Tried it without the altitude Compensator or checked your hoses on the compensator for air leaks/clogged filter?
May also want to insure you don't have too much oil in your air filter and or your crankcase vent is not dumping oil in your airbox at high RPM

75MPH, Now thats some serious SPEED..

Bike is running good, no flames. Didn't do anything. Got 76 mph by speedometer on gravel road, slight downgrade.
