Well it dynoed out a little lean worst point was around 14 air fuel ratio. But ie is pumping out 75 HP 98 ft lbs so I and going from a 172.5 main to a 175 or a 180, and the pilot is going to a 37.5 that should get it right on the money at 13.1 AF. Not bad for the first try HUH? BTW check out my Mr Cancilla's copy air cleaner.

You are the carb man! I like the air cleaner a lot! Is that skull etched in there?

Nice work Curt. Where can I get one of those air cleaners mate?

Looks great and runs great too! I can't believe how fast you put that together..

It is a K&N and I had to order it Emo I will get the number and post it on this thread. The skull is a chrome stick on that I found at autozone. You have to make your own mounting bracket for the filter.

Thanks Curt. Another project for the list that keeps growing longer and longer BTW... Black Ice II is looking good.

Nice work Curt

Way to go, man! I am impressed!

14 is not lean if it's cruise range, yes it's lean for WOT though, the info I used below to dial my carb in, I used an afr of 14 for cruise, and 12.5 for wot.

Operating Mode


Recommended AFR

Cold Start (first 30 sec)(choke). 11.5-12.5

Idle 12.8-13.5


Part Throttle Cruise 13.0-14.0


Wide Open Throttle 12.5-12.8 (values down to 11.5 may be used to reduce detonation)

the full article I used is here: http://www.daytona-sensors.com/tech_tuning.html

I'm with Erb on this one . I used the #'s he posted and the bike ran great. On a test run @ 65mph I got 50 MPG. When I dynoed, the bike had a air kit,and stock stage 1 exhaust. It dynoed 68.03 Hp and 98.74 tq. I went a different route on the jetting than most. I kept the 182.5 main. I figured that if that was the main for the stock setup, regardless of needle brand then The bike can drink that amount of gas and will result in the best #'s at WOT. Then I did my tuning with a speedstar needle that is made for these bikes and made to use with stock size main. tuned the cruise range with changing the pilot to a #45. It needed a PMS adjustment after the dyno was done and did that with a gas anlizer. AFR was 13 WOT, and 14.2 at cruise when dynoed. I made a change to my needle with 1 washer and havn't had it rechecked. I will soon, now that I changed the exhaust and ported the manifold. I expect some good #'s
Good luck with your new Ice. I'm sure it will run as good if not better than the old Ice when your done.
