I just got the shee put back together after pipe, carb, peg and nerf setup change. I bought the carbs used off ebay and are keihin pwk's, I'm guessing 30's that have been bored to 32's. When I start it it redlines, and I have to kill it within a few seconds. I tryed it with choke on and off and its the same thing. It might have been just a hair worse with the choke off or it might have been in my head. I am unfimiliar with these types of carbs, so it may be a simple solution, I just dont know how to fix it. What is the probem?? Thanks.
