Took the cb450 out for a ride around the block today and it acted a little funny. if i went to give it throttle after idle it would rev fine but if say i had it at 1/4 throttle then went to give more at speed (15 mph) it would act like it was trying to rev but unable to. immediately letting off throttle to idle then back it would rev fine again. Not sure if a mixture thing or maybe a spring loose on the mechanical advance? I did notice one of the springs were a little loose on the advance but had read it was best to leave them alone.
