Johnny . Being that I may get another crack at my patch . my 60 foot is great but may re think the gear in it .. what ratio are you running ?

3.46 final, its a 5 speed bike.  I run the 2.94 first gear, and have switched to a 2.08 second.  Not sure on the 6 speed bikes how to gear.  What gear do you cross the stripe?

I know but that was my shining star run HA HA  i told myself I no longer cared the track closed but THEN ..   You know the " THEN" happens and well got some new goodies for the engine and it should make a touch more power .

I made 124 mph after I figured out track tuning.  I use a WEGO III.  I was really surprised how much fuel I added to get the AFR I wanted, and track AFR my best mph was fatter than dyno AFR max power.

innovate LM-2 is great as well .. I found the same thing .. However After looking over the data logs , setting the AFR , then back on the drum I found that inducing a % of load on the WOT pull I could duplicate it .  But each bike is different .. based on the power you make. I am sure someone could come up with a scale . But mine was 11% load   if I recall I would have to look at my notes.

Steve we found both on the engine dyno and the dyno jet that a combination of  step testing and sweep testing gave the best results for mapping AFR for the track. If you data log at the track you can get a decent acceleration rate for both launch and individual gears and then replicate that with the dyno. This is also a big help in getting the ignition timing correct because as you already know that will change the fuel requirements. Looking forward to seeing your gains at the track with your renewed effort.

I really enjoy discussing and learning about tuning for racing. I try to explain to others that tuning isn't just about getting the engine to run right, but to make it work as a whole package with the transmission, suspension (especially in road and off road racing), braking (same), tires, tire pressure, and how the motors needs change as it goes down or around the track. Now throw in some weather, and everything changes again. Keeping good notes is key to success and again, a commitment.
I am in awe of you that race and keep that commitment to getting better every run. And even if it is not better, it is such valuble information to improve upon.
Always try to go one faster. Good luck to all of you.

It was a bit of trial and error .. many factors .... But the 12.8 AFR I had set was running in the 13.8 range if I recall I have the card i could pull it back up .. But i was surprised at how lean it was getting under load on the big end..  I just look at the time and adjusted the PE fuel when I was at the track it was easier .. I know have it dialed in ..

same here, quarter worse than eight.  I tnt at eighth mile a lot.  Bike made most power @ 11.7 on dyno, 11.5 is what I shoot for at track.  I use E 85. I started playing with nitrous and that's another curveball when I started pulling timing
