Keep up the good work Brian!
My mileage is holding steady at about 40mpg. It's actually been a bit lower since the rebuild because I've been wringing the engine out harder than before.

I've been using 91 octane only and haven't noticed any pinging.
I did do a couple other little mods in the last couple days. I removed the old 8 gauge wire that ran from my starter relay to the starter motor. I replaced it with a high quality 6 gauge wire that was about 5 inches shorter as well (something about Ohms law from college

). The bike starts way easier than before, almost jumps to life. I was going to upgrade the batter y cables as well, but there is a kind of switch attached to the positive one that has a second cable running off of it. I couldn't figure out where it went so I decided to leave well enough alone.
I also installed a little oil temp guage that screws on where the oil fill cap goes. I think it's made by a company called moto detail. (I've had a couple beers so my fingers arent' following directions) I ordered it from a company called Monsterparts. Really fast shipping and the temp guage works great. She seems to run staeady between 90-95 C. Idling at a light will creep to 100 C pretty quick.
I think she's about done for a bit. Dyno day on Monday!
Cheers,
Jeff
