Bike dies when throttle engaged

[blaine]

Yep pilot screw should have spring,washer, & small o-ring.....There should be one in the kit......

You may need to drill out the plug to get to the pilot jet if it hasn't been serviced before. I had to drill mine.

full choke and crank.
modulate the choke for the first 10 to 30 seconds then settle it into an idle.
If I simply get on the throttle it will just die.
if I rev rev rev rev the throttle really fast to build revs I can get underway.
warming it up is best done by short shifting to prevent overrev but keep the throttle pinned.
after 1 or 2 miles I can keep it running fairly easy.
Less than that and if I don't do everything perfect it just dies over and over.

Found a Mikuni carb expert website.
It says Pilot circuit problems or vaccum leak.

Thing about a vacumm leak is once you get it started and idling if you hose
it with starter fluid *auto parts store* it should react big time.
Be johnny on the spot with the ignition kill and a fire extinguisher though.

I plan on trying this on mine.
Don't spray the carb intake. It's prolly not your problem. Spray the boot between the engine
and carb and the carb itself. Assuming you have a vacumm leak.
The intake of the carb will react even if the carb is perfect.

Don't overspray. If you have a vacumm leak it should react dramatically.

What is the address for the Mikuni expert site? I can't find it!
