I have an '85 Indy 600. I am putting a 650 RXL engine in with 38mm carbs. I have a set of INDY 600 PSI pipes that I am thinking about running. Anyone have a jetting baseline for me. I don't know if I will get too much grief with these as far as the law goes. I haven't heard one with pipes in almost 20 years. Thanks

I had a set of these years ago and yes they were loud. I guess I don't remember how loud.I really want to hear them, but this sled is very clean and I don't know if I want to chop the belly pan to do it. Let me know what you come up with. Thanks!
