Yes, front coil - front cyl, etc. What made me think weak coil, will fire one but not both. Could also be a pickup, not enough saturation for some reason. ... or CDI.

Knifemaker I'm thinking weak battery.....

As the bike runs with the plug wire reattached (after it starts)

Spockster Maybe discovered while checking for spark?

I'm thinking a weak coil, maybe CDI problem, but I'm waiting to see more details. If it's just on one coil, ohm test that one. If it's on any wire on either coil, may be CDI.

Knifemaker Perhaps you need new plugs. Am wondering how you discovered this. Seems like an odd procedure to try.....won't start? Pull a plug wire off?

Spockster Does it matter which wire you pull? Left, right, front, rear?

Do you get spark on the loose wire?

glenn_nemeth no+++ it does not die

Knifemaker Does it die if you reconnect it?
