2003 XB9R, stock ECM with a Techlusion Fuel Injection kit, K&N filter, Drummer muffler. :wonderlan

That dip is fixed; it was running dangerously lean right in that cruise spot. And in case you haven't noticed, torque scale is Nm, not ft-lb. So divide by 1.36.

Hi.

So, on the second run, was it Popping back to get those drop outs?

Good to hear you got that dip out of her, so does she still hit 90hp?

The second run looks like first thru fourth gear. Or is it second through fifth. No idea how fast an XB9 goes. Notice the scale is in KPH.

I'm sorry I hadn't mentioned it. The two graphs are the same run. I only did one run.

The first one is fifth gear pull, the second is through the gears 2nd - 5th.

She did 80hp at 7100rpm, 88Nm 5850rpm. Not an aweful lot you might think but realize the bike is only 385lbs.

I got rid of the dip with the electronic jet kit (I can feel it's less in a pull from low rpms). As you probably know, the Buell has fuel injection. I have a device installed that allows me to tune fuel injection using 4 pots. One of them is similar to the main jet on a carb. I increased that by 1 clock position, which is equal to 5 points on the main jet.

Of course I can never know if its perfect until I get her on a dyno again but I will pick one that can make me a A/F ratio graph. This one couldn't; he had a separate system for A/F ratio check that he watched during a pull.

A note on top speed, he didn't pull til red line, it will top out at about 135 'real world' Mph, according to the book. I have done just over 140mph on the counter (which probably equals 135 in real world).
