I might ought to mention, there was one other difference in my bike between Dyno 1 & 2 vs. Dyno 3 runs.
My first two runs were made with Krause Racing Ti sprockets and Sidewinder Smart-chain. Just before the Dyno 3 run, I changed to Supersprox combo with RK-xwring chain. Kept the exact same gearing ratio at 13/46, but only had about 300 miles on new chain & sprockets prior to Dyno3.
If anything, I would expect the heavier (new) chain and sprockets to yield more drag. The Sidewinder combo is claimed to add about 1.5 hp. So, I might of had an even better result running the original combo, but it was totally worn out.
Doesn't really matter to me, but I thought you ought to be made aware of these minor changes which could have affected test results (slightly). FWIW
