Welp, I did my highway speed ride today. A little over 60 miles. I did refresh the ECM with my tune and added 4 oz. of sea foam to like 3/4 of a tank.
First step, the O2 Sensor voltages were consistent with each other which its what you want.
The trike ran as well or better than it ever has. When I got to I 70, I "got on it", which is unusual for me, and I guess I've never really "got on it" that hard. Frankly, I was impressed. The Fat Bottom Girl can scoot when I let her. I never went over the 75 mph limit or the 80 mph limit ... but I got to it pretty dang quickly ... LOL ... kind of fun.
At the end of the ride, I filled up, just incase there was some bad gas (dilution is the solution to the world's pollution). I put 4.232 gallons in the tank for 135 miles = 31.89 mpg ... 72 of those miles were "around the valley", various speeds under 50 mph. So, 63 miles of it were at 70-80 mph. Couple that with the fact I did the Jack Rabbit Start thing twice, once getting on the highway, once in Utah were I turned around to head home. Pretty sure the trike is not running rich.
As a side note, it was 55*, the ET never got over 202*, that was at 80 mph, the head temp never got over 255* at 80 mph. After the high speed run, when I pulled into the gas station, I checked the oil temp in the tank with the digital temp gauge, 192*, oil pressure 34# at 80 mph. Good numbers, better than I had pre cool and clean.
One last good number, the Power Vision reported 32.0 mpg when I filled, so +0.11 mpg off, close enough. My work is done.
When I got home I looked at the end caps. To me they looked cleaner. Didn't get a before pic, but, here's were they are now, they were blacker, now, more like dark chocolate.
