    GS550L 4500rpms

    Hello, Im having a problem with my GS. It is a 1981 GS550L. It will start with a high idle (2000) and will rev up just fine in neutral. When riding it it will only go to 4500 and then break up. Ive cleaned the carbs, replaced the coils, cleaned the tank, cleaned the fuel valve and ran a can of seafoam threw the tank and vacuum line. It ran fine for a while without the air screen and top of air box. Now its back to the 4500 problem. It also seems to hesitate when starting off down the road. Any ideas, Im still fairley new to this.
