I have found my bike is very tempermental to ambient heat, riding atm in Australia with ~27 deg C (80 deg F) ambient temps has made for a wide range of performance issues. At first the bike runs great then after ~10mins of riding when the bike is really hot it starts the hesitation issue under load on hard throttle. When i ride in cool temps <24 deg C (<75 deg F) there is no issue. I thought it was a fuel starvation issue and have been chasing that to no avail. I recently took my bike to a friend who is a long time rotary expert and has a couple of RE5's himself, he diagnosed the problem straight away. (he had the same issue with his) In short the timing was not set up correctly for hot temperatures, causing detonation. He took a couple degrees out of the timing and it has run fine since. (mind you it was only 2 days ago) but on first ride back in traffic at over half temp on the gauge with fan on it didnt have the dreaded hesitation ive been chasing a fix for since i got the bike. It also felt like it was making more power. I went for a ride later still in hot temps on my normal test ride route of ~30km and the problem only surfaced slightly once on an elevation change up a small mountain. I turned around and redid that same piece of road and the hesitation was not there so go figure lol. I am still yet to change the jets, it currently has PMJ 87.5 and SMJ 180. I have a 95, 100 and 182.5 to try out soon. Interestingly he said he runs a 195 SMJ in his with no issues and it got rid of any hesitation on transition.
