Short story, I NEED HELP! Longer story. Have a 750 we just picked up. starts right up but after 10 seconds just start going up, likes to run about 5250. checked valves, installed new boots from carbs to intake, cleaned out carbs, like i said she starts right up. Where should i be looking? After it cools down i am going to hook up my sync and see what it says. even with throttle cables unhooked and ideal back all the way out after 10 sec it just starts going up could it just be to much fuel? any thing would help and i really appreciate it in advance. Think i hit the wrong garage the first time.
