If you are running 120 s now and you need to go up to a 130 for the new pipes. I wouldn't ride it at all my self. The jets are easy to change, and they are not very expensive. You risk burning a valve is the main problem. That's not a job you want to do.

I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago. Edgar Allan Poe
