Change your jets already....geez, it takes maybe 10 minutes to do. You'd be willing to rip it all apart and start over rather than pull the carb bowls off and change two main jets? :shoothead:
You can't blame Duncan because you're jetting is off, that's ridiculous. Everybody's setup is different, there's no "set" jetting for a port job; there are too many variables to consider
I can totally understand why they are against the T6's...T6's were designed for stock port engines. It's not fair to knock the engine builder because you don't want to take his suggestion. If you were doing what they recommended and it still ran like crap, sure, you can point some blame at them...but this is not the case. You should change pipes anyway now that you're running ported cylinders...T5's, paul turner high revs, anything but T6's :shrug:
