Also... when you read in the reflash thread that "higher octane fuel is recommended with the reflash" , be aware that I put that in there for the express reason that some guys, in the hotter climates, were having issues with the bike stalling at the lower (660rpm) idle and they reported that running the higher Octane fuel helped to alleviate this problem.
Since then Don usually won't lower your idle beyond 700-750rpm unless specifically requested and you acknowledging that you understand that your bike may try to stall at idle.
Aside from that the higher octane is really of no benefit because Don doesn't go to the extreme when advancing the timing on these bikes.
