How or what did you use to measure the component temperatures with?
If it's an IR signature then surface type (and color) will affect the reading.

Chains are inherently prone to make more noise particularly if they get a bit loose.
The lubricant used on a chain can absorb a few horsepower if it is very thick oil or if it's an 'o' ring chain.
Also thick chain oil will make the chain live longer but you pay for it in reduced horsepower.
I use a light Teflon-based lubricant just for minimizing power loss but it requires I lube it about every time I ride .. plus it is more messy.
However, I use it just for dirt track racing so a chain is necessary.

For street riding I would select a belt because it's quiet and minimal maintenance.
For racing I think a chain is best for changing ratios and resistance to foreign objects (rocks, mud, etc)

Thanks MotoRyder for your nice comments. The electric motorcycle has a bright future with its smooth and quiet power that makes for a most enjoyable riding experience.

FWIW: Works performance made a custom shock for our 2013 MX dirt tracker that has worked really well. We had spent hundreds of $s on trying to modify the stock Fastace shock to no real improvement. The custom WP shock solved all our rear suspension problems.

Awesome!  Can you please post a list of your mods and future mods?

Sure, I'd be happy to. However, it will take me a few days to collect and organize
the past information. (something I should do anyway)
For the future, I can only identify the objectives and a SWAG on how to get there.

Thanks for your interest in electric flat track.

Most people are quite interested in this 'new' technology and remark about its silent operation.
Competitors remark that they can't hear me coming, but no real complaints...yet!
The announcers usually make mention that it's an all electric powered machine
so that gets spectators interest up.
It's kind of a 'thin edge' right now in that we want to be competitive but not display a
machine that they might feel has a superior advantage.
If/when that would occur we might have to only race it in an all electric class.
(problematic because we are the only electric machine out there)
No worries, for the time being, since the gas powered machines have the better part
of a century lead in machine development.
As battery power density/cost improves and better tuned power delivery from the motor are developed it will become the machine of choice.
But I think that will take years, not months.
In the meantime we will try to add a bit of improvement to electric dirt track racing.
Thanks for your interest in it.

..... If I was your friend and he wants to ride on his dirt track within the next year or two, I would go out and buy a Zero MX.  A Zero under your butt is worth two Freeride E's in a KTM dream.   

That's what we did last March. Got a Zero MX and spent about a month preparing it for dirt track (wheels, tires, suspension, etc). In April we first raced it to find out where we were on the setup. In May I got our first win on it at Perris SCFTA track. Got another class win in June @Perris and a couple of wins in July at Ventura County Raceway. They are all fairly short tracks (under 1/4 mile) so using just one (45lb) battery is sufficient for the event. The 'all-up' weight is 228lb with one battery and 273lb with two. An extra 45lb up top does not help handling so we just run one battery. If we can get it hooked up well exiting the corners it runs comparably with 450s -750s down the straightaways.

Yes, due to the lighter weight it seems to get off of the gate a bit better with one battery. (less chance of excessive wheelspin).
Using just one battery seems to make very little difference. It's got about all the power that the available traction can absorb (much extra wheelspin just slows it down). It appears that just  duration is the primary difference between running with 2 batteries vs one battery.
