I just picked up my first bagger which has the 103" in it. I plan on going for bigger numbers with head work, cams and upping the CR to over 10 (not sure exactly where yet). I just ordered my Fat Cat. On my last bike which was a 95" with 100/100 I had the Ness Sucker stage 1.

Is the Stage I Ness flowing enough air for a built 103 or should I jump to the stage II? Any other suggestions very much appreciated.

 

The cleaner you have will be plenty.
