Hello all. This is my first post. I am wrgreen an artist and lover of all transportation. Live in SoCal. Building a 1980 SX650 with my son. We have come upon this problem ... starts great runs good when cool but when it gets towards warmed up it will not rev up. It just comes up flat like a rev limiter on a car. The carbs have been apart and all looks good. I am starting to think it is related to ignition but a bit confused how the heat could alter any of the components. I could sure use some help
