What elevation are you at? Did you just change the pipes or rejet as well? Im not a 33pwk expert but the jetting sounds pretty fat to me for a mild port. I would start leaning the needle first and then drop the pilot if necessary. What do your plugs look like after wot?

I would drop the main a size down. See if you get a screaming top end. Then lower the needle one clip. Don't do them at the same time.

 

 

 

You want to get the main 100% dialed in before you start messing with the needle. That way you don't mis adjust the needle to make up for the wrong main jet.
