2650 motor timing?

I can't really get into the science of the matter as I simply don't know but I have tried playing with timing a fair bit. With some motors the difference is very miniscule but on some performance increases are obvious. Thing is regardless of whether I got a performance increase I always ended up with hotter everything after jacking up the timing. Motor it self, ESC and the batts were all considerably hotter so proceed with caution. Maybe wait till one of the other more knowledgeable guys chimes in.
