Just wondering if anyone has any dyno charts of like a 38pwk vs a 41pwk on the same motor. I have a midrange ported cylinder and I put a 38pwk on it but the carb must have been messed up. Could never get it to clean out no matter what I did to it. Put a 41mm ESR bored carb on it and it woke it right up. Runs really good up top for a stock cylinder. But I am wondering what I am giving up with that big of a carb. Thanks.
