Hey 1997 bagger, they didnt use the bung in my headpipes, they had a sniffer up the pipe. That is some good info you posted. I will be doing some runs and post the results. Thank man.
I will add this.
See your from the south, also. Gets real hot & humid in the summer.
1997baggers numbers were pretty much ,spot on. I drove to work, in 95-100 deg heat, these past summers with no problems. Tuned it a tad on the rich side.
I've got about 9.77:1 static compression, 9.08:1 corrected. Around 187-189 cold cranking compression & I do have compression release. I'd hate to try & start it on a hot day, without em. But I do just run 93 octane with no problems, also.
1997bagger will give ya the straight scoop.
Good luck.
As Bagger said, make sure the pipe is not your sag in the bottom end. You can cut back on the accelertor pump and record runs to see how it affects the rate of acceleration in rpm's to time to AFR. I've logged the data at .25 sec sample rate to be able to see it better....

I'm pretty sure that's the same sample rate I used , also.
It did make it easier to see the graph.
One other feature I used was the ability to write in, & save, what jets & shims I used with each graph. Made it easy to keep up with everything .
Ride Safe,
Harold

In the beginning of your run up to the point of 1773. your entire run was very lean. we're you riding or sitting playing with the throttle? Did you make a jet change at that point? You need to add narration so when we see a change it would be easier to decipher what you did.. What jets are you running from 1780-2045? The midrange and top end look good.So I would say the main jet is a keeper.
From around 2016-2086 It looks like you were just tipping in on the throttle and maybe actually lugging a little, however based on that short segment I would think you need to up one on the Pilot jet.
Remember to log all changes by the time frame and right it down...
Looking pretty good though.
Did you seriously take it up to 8100 rpm @2093?
Don't think a twin likes that much.
