I got to thinking about the BK mod last night and had a question maybe you all could answer: Is the APJ interchangeable like the other jets? I thought that if I could get a smaller APJ then increase the squirt duration that I could get the same amount of fuel delivered to the engine over a longer period of time that maybe I could achieve even better throttle response. Plus, if I could get rid of the adjusting screw for the cam, that would eliminate tuning it each time you've got it apart for other maintenance. Another question, does anyone make one of these APJ's that has a mist pattern instead of a stream? An aerosol (sp?) of fuel would ignite easier than the stream. I was thinking this might also help. If you guys know of any suppliers for these jets that has a website or I could call I'd be interested. Thx, Brian.
