she caughed and she sputtered.....

Hey all, got a bit of a problem for you to diagnose.

the 3rd degree doesnt seem to like the cold, but its an eleven, so were good there. When firing the bike off, either the first time of the day, or after the bike has sat for 1+ hrs, it will fire off on the choke circuit, RPMS will rise, after a short warm up, I drop the choke and go to take off. This is where the problem starts. On slow throttle increases (letting out the clutch to leave in first) the engine will suddenly starve at about 2k rpms. 99% of the time it will not die out, but will lose all power. I have to let off the throttle completely, return it to idle, then get on the gas again. It ususally just does it when the motor is cold, but after a half hour 'around town' ride last night, it still would do it occasionally. (1 out of every 15 stop lights)

I have pod filters and 120 mains on her and have shimmed the needles.

Could it be a vacuum problem?????

T.I.A.

Classic symptom of pickup coil wire problem.

Mine did the exact same thing. Bad wire in the pick up coils. IMHO much easier to deal with than a carb problem.

[HobbyMan]

I agree with you. There may be a slight chance it is carbs but most likely wires. Everytime you change the throttle position, you are moving the coils. You are kind of in the right area when you said "vacuum problem" since the reluctor coils are moved by a vacuum diaphram.

[Bauer]

Where is the common fault point when you pop the inspection cover off? Its right where they bend the most right????

[DiverRay]

It's usually the front coil, and the wires break at the "clamp" they ran them through. I fixed mine, and loosened the clamp a little so the wires will just slide. I've been good for the last 35K miles.

I installed a brand new set of pick up coils. My problem was at the connector between the "regular" wires coming from the harness and the "bendy" wires connected to the coils
