Jon:
Couple Items:
1) Regarding tune, you might want to double check. Should be the EH Super X tune which was privately developed post production, and the only shops are the EH Shop in MN and Marty/Jamie Atlantic EH in Virginia. All other tunes do not operate as well and this tune helps lower the operating temperatures. Of course these bikes will run okay with many different tunes, however this Super X tune is the most optimized version available. If you do not have this tune, then Atlantic EH will install the tune if you ship them the ECU.
2) When you get new tires, I recommend the dynabeads for balancing. Do a google/bing search to verify if you like, and more info on the Official EH website in the tech area. Riders that have taken this step have noticed an improvement in the ride and wear of the tires. Dunlop Elite3 many people use. The rear will indeed take one size larger...contact Dave Lockhart for info or Marty/Jamie. Their contact info is on the EH website in the tech area.
3) Not unusual for you to notice vapors or moisture, etc...especially on hot humid days and the engine idling...heat/temp of the motor is rising rapidly. There is no perfect answer on this as some engines will exhibit more or less than the next and they both run fine. There is a lot of air flowing through the crankcase in a running engine and with an exposed external breather/vent one notices it more...cars were the same although today they have a pcv to draw the fumes into the motor. Cars of old (till around 1962 by law) they were allowed to vent to the atmosphere and very common then to also see vapors from a running engine exiting below the motor. So generally hard to tell if excessive...if runs good and oil level stays okay, then ... As suggested, the re-routing in the rear fender is quite common.
4) Fan assist cooler certainly would be suggested in FL. Again, Marty/Jamie have a great setup on one and others have suggestions too.
