The right cylinder on my 1979 Yamaha XS650F has gone dead. I just cleaned the carbs and when I put them back on, the right cylinder wouldn't fire. With the bike running, I pulled the spark plug boot off and nothing different happened. I stuck a screwdriver into the boot and held it up to the plug. The spark jumped about 3/8 inch and the cylinder fired up and ran like nothing was wrong. Moved the screwdriver closer to the plug and the cylinder died. Put it back on the plug and nothing happened.
I changed the boot on the plug wire and got the same result.
I checked the gap on the plug and it is fine.
Left exhaust pipe smells like exhaust. Right pipe smells like straight gas.
I need some help. Can anybody help me figure this out? Has anyone experienced something similar?
Thanks,
Andy
