AAEN pipe jetting on Indy 500
SO I've got a set of AAEN pipes I'm putting on my 89 Indy 500. My question is whether or not I will have to do any jetting to accommodate these new pipes. I'm assuming I will, but I'm not sure. If it's any help, last year when I was riding near full speed the sled would actually pull a little better with the throttle not quite wide open. In other words, it runs better with the throttle at 85-90% than it did wide open. I will be taking the motor apart to do crank seals and rings/hone if needed. Thanks.
