Currently the bike will start from cold, run for a few minutes and than it will die. When running, although I had the idle turned up it would still reach up to 7K RPM, than all of a sudden it will peter off and die completely and will not start again unless it sits for a while, making me think its flooding or something electrical is over heating. I have replaced the ignition coils, plugs, cleaned carbs, tried without the regular gas tank on. It seems the right plug will come back wet after it dies, indicating it could be flooding. The floats are not stuck. Also thinking it could be related to timing pickups, is there a way I could have screwed them up? I took that unit apart when I was getting the bike un-ceased after it sat for a year.
Tank vent clogged?
Are you using the choke or just the idle adjustment screw?
Well we took the tank off and made another one with an old oil bottle and it still had the same problem. does it matter if the vent hose doesnt have something hooked up to it?
Doesn't matter, but the CARB VENT hose should be clear, not clogged with spider nests or something ... carbs gotta breathe , lol
When it starts to die, spray some starter fluid or carb cleaner or even wd40 into the filter air intake - just a little, like a mist - if the motor revs start to pick back up then you have a fuel supply problem.
If not, then probably electrical. After it dies do a spark test, plugs out and well grounded - should see a fat blue spark.

please.. regular text?
Why yellow and so big?!
Any updates?
I havent been back to check the carb vent hose (the one that goes to the bottom of the tank). As far as I know I blew all the hoses out but i havent had a chance to go back and double check. Might be this evenings project I'll let you know. Also when the thing dies it dies fast, but i'll try the starter fluid in the filter box.
