 Out and about. Getting closer and closer on the carb tuning. First tank got me 40 MPG, which isn't bad considering all the fiddling I've been doing with the carbs. Picked up a new timing light and double checked the timing. It's dead on at full advance on both coils. Got the mixture screws back out to closer to where they should be. Running pretty good, too!

Rode it up to Cyclemania - Charlotte today. Took the back way in and put another 100 miles on her. Ran great. It has a really nice mid-range and pulls well at 4K and above. I took it to 7k for a couple of quick bursts on the way home. I still have just under 300 miles on it so I'm gradually increasing the revs.
 I haven't looked at the plugs yet, but it seems to run well. I got about 37 MPG on the last fill up, which isn't too bad. Could maybe be a little better. Haven't looked at plugs again. Gonna let her cool down first.
 Speaking of cooling down, as soon as I hopped off and removed my helmet and gloves, I hit it with the IR temp gun. I'm getting about 235 on the cylinders, 260 on the head and the exhausts were 385-400 right at the exhaust port and the bend. I've found that bend is always the hottest part on any bike. Just a few inches down the headers and the temps drop to 350-365. I don't think that's bad, seeing as I just rode it an hour home and it's not exactly cool out today.

 Parked next to this nice CB750. Is that any of you guys?

Swapped out the aftermarket mirrors for genuine Honda. MUCH better as far as vibration, and the actually sit lower and slightly wider, which really cleans up the lines too, IMO.



 Also added a little HRC "bling".



 Just love the way it turned out, if I do say so myself.

 This bike is up for Bike of the Month over at SOHC4.net. I'm up against some TOUGH competition, and it's always hard for a 500/550 to beat a 750. If any of you are also member there, I sure would appreciate your vote!
