well the other day it was 68 degrees i did 80.7mph on the seat gps at 8480rpm according to pet tach today 90+ degrees i am down to 8150-8200rpm and i am at 77mph also at the 4-5 setting on the powershot which is where r&d keeps it for r2 reflash i am at 11.2 afr where i see most people are at 12.0 or leaner i bumped it to the 3 setting on the programmer and gained alittle and my afr was at 11.8 should i repitch the prop to gain the rpms back?should i lose that much rpms with the heat?

74.6GPS with the R2 and in the process of depitch. My RPM's were 8000-8050. Target RPM's that I would like to see are around 8400-8500. RPM's in my opinion are paramount! Mine is running with a 13/24 Skat for the record. (not verified but I'm guessing thats close to right, and if not maybe it's a 13/25)
I'm pretty sure I have no idea what I'm doing, but I'm throwing the stock prop on just to see my RPM's go past where I need them before I do anything. For guessing purposes I'm thinking a 14/22 or 14/21 will serve me better. I will for sure be sending out some PM's with my stock numbers for the experts to chime in with.

In my opinion, its ALL about the weather.
I can fluctuate from 8550 to 8200 depending on weather conditions.
With this said, I'm wondering if changing the nozzle ring from a 83mm to something larger would help offset the lower RPM's due to "poorer" weather conditions (humidity, barometric pressure, cloud cover, Air temp, etc), and retain higher top speeds? It sure would be easier than having to change props to accomodate the weather. I'm just wondering if you would gain the speed back with a larger nozzle and the higher RPM's? or am I off base here?
I know for me 8500+ rpm's = 82+
