hi everyone, I have a 1969 series 2 750 that runs very good! The problem I have noticed is that the left side carb does not have very much draw when you put your hand over the mouth. The right side carb sucks your hand into it and will shut the engine down.
boyer ignition, timing is dead on
brand new amal carbs
recent valve job
bright blue spark
carbs are sync properly
compression is 155 on left 150 on right
bike starts first kick
left cylinder feels colder than right but eventually gets hot.
any ideas?
