Mine didn't even start after the first long drive had to get a boost it went and never did it again but yeah sometimes it'll turn over slow at the first press of the starter button when it's warm.Anyone else having an issue with the engine barely turning over after going for a long drive, turning it off for 10 or so minutes then trying to start it up again?
This is a great idea!!..if and when mine don't start again I'll buy a battery like that..thanks for this info.Check battery leads and the starter. I always thought my Mav turned over a little slow so I added a AGM battery that fits a 2005 Mazda Miata. Mounted it under the drivers seat and connected the positive lead to the starter relay and the negative lead to chassis. Went out for 4 days running the stereo, lights and in the warmer weather with no problems.

right next to the battery is 2 resonators and a cat , creates and keeps tons of heat , batteries can lose power volts amps when they get warm , could be a slight chance its electrical ,Have you checked your valve lash? From what my Rotax mechanic friend tells me, these motors tend to tighten the valves (decreasing lash), this would make warm startup difficult. I doubt this issue to be electrical, most likely mechanical if it's only when the engine is warm.
ambient heat and resistance heat are not the same thing. resistance in an electrical circuit causes heat, not the other way around. in this case the heat is ambient heat from the exhaust. this heat does not change the resistance of the 12V system. however repeated charging and discharging in high ambient heat will continually shorten the battery's output cycle, meaning the amperage output will remain high, but it will be in shorter and shorter bursts.Yes on the heat question. Heat = resistance which cause a larger amperage draw.
