Fuel from the left exhaust

Post by ensoniqdude » Thu Aug 07, 2014 12:03 am

Starting up a freshened 1965, CA77.

Noticed some fuel blow-by coming out of the left muffler's drain hole on startup. (Grey smoke as well.)

Bike ran, but with power issues. (Low power, weak ecceleration, etc.)

Any tips?

As its a 360 crank you could try connecting the plug leads to the opposite plugs. As they fire at the same time. If the issue transfers it may be you have an electrical fault.

Just a WARNING if fuel builded up in the muffler it could ignite and you will have a split muffler I have seen it happen right down the seam.

Was it fuel or condensation?

Definetly fuel.

Will check and swap the plug wires.

Frustrating of course after several weeks of "resto-freshening".

Just to clarify you are just disconnecting the plug end and swapping over, leaving the coil end intact.

Yes, understood.

Swapped them around this morning and the problem still exists.

Odd, I know.

Had the timing light out yesterday and wasn't getting strobe on the left side. Swapped the plug wires and still wasn't getting strobe on the left side.

Still getting fuel and white smoke from the drain hole from the bottom of the left exhaust.
