Hancock,
Let us know what Travis comes up with in regards to your sprocket gearing - I bet you have the lower gear set. I haven't checked mine with a GPS but I bet it's some where around 20-22 mph. I'll try to confirm it the next ride.
Here's my take on the engine bay heat and what I'm going to do to try to reduce it. The engine driven cooling fan is ducted TO the engine but does not duct it out of the compartment, I'm going to build some ducting to continue that air flow around the exhaust and out of the engine bay. The auxiliary cooling fan does a poor job of collecting the heat and removing it from the compartment. I'll also install the bigger fan when Matt has them available but will duct it so it's more efficient. In the mean time I've wrapped the exhaust, helps a little bit but I'm still planning the other mods…
I have to echo others comments about buying an early production machine and the bugs that come with it, even with these minor things I'm still very happy with my purchase and have no regrets.
Regards,
Brian
