you could be too fat on the main
, it's like flooding the engine, just can't burn all that gas, and too rich will also rob performance.
I had a 167.5 for my set-up when I had the stock carb
. Might want to try a 170 or a 172.5 at the most.
I have the Dyna3k and set rev
limit to 5k, and thats all you can go with a 1600, unless you change the valve springs, but regardless, 1600 or 1700, there is no more gain past 5k rpm
. In 3rd I can hit 99mph, but most will only get to 85 to 88mph. Tops I had it to 105, and still had throttle
