Hey spaceman, you know, I put a dynojet jet on mine and it also seems like I lost a little power, idles fine and good throttle response, but it won't turn more than 6600 on long straight stretches . I've also asked for any tunes peeps have used but no luck. Emerson uses a auto tune on his, but I'm not sure I want to try one as his just burned a piston.
Would like to richen it up a little but not sure how, as there's not much adjustment with the dynojet.
