Have had some more drive time and everything is really seeming to run better than ever. The O2 sensor seems to be right where it should be at most times. A couple times I've been able to peer down at wide open throttle it seems like for just a second it goes lean and then drops pretty rich down to between 11.5 and 12.5. But I really need to take it to the track where I can keep it wide open a lot...
Getting rid of that stock radiator and shroud and putting an aftermarket radiator has so far kept things pretty cool. But again we haven't had any really hot days. I rarely have to run the fans when I'm moving. I think at the very worst I may have to get one big fat Pusher fan in the real heat of the summer.
Another great decision was those new 354 gears. Still plenty of get-up-and-go but able to cruise in 3rd gear around town at a reasonable RPM...
Also the Nitto 555r definitely great traction on the street so far..
