Carbies have already been cleaned and balanced, ignition checked and ok. I have sprayed aero-start all over the engine whilst running and that had no effect aswell. All air solenoid assembly has been cleaned and checked.
Today I removed the airbox and ran the bike for a few minutes just to see if there was anything out of the ordinary. I did notice a small amount of fuel being expelled out the carby throat on the lower cylinder while giving a little throttle. At idle there was only a sucking effect. At this point the exhaust is still sucking.
It would appear that there is only one place for the air/fuel mixture and air from the exhaust to be going. I guess it's time to break out the old leak down tester.
You would think the cylinders would work as a team but NO, one has to get greedy!!!
