MB,
If a rise of only 1000' is really affecting your performance, I would tend to believe that you are too rich. A 1000' gain is really very small for a 4 stroke engine. When I take my buggy out to the desert, I see about a 3000' gain, and the only real difference that I see is the amount of choke I need to fire the engine (manual choke). This is on an 170cc BBK, with an A12 cam, PNP head, custom exhaust and redneck intake.
