Thanks to earlier post I copied and took into my BMW dealer. My bike was hard starting since new now 30,000mi and was still hard starting when hot. They always checked batt but the post of wa state BMW owner said BMW had a fix to a larger diameter wire from Batt to starter. My dealer verified through his rep and was sent the specifics to do the change. It works. Motor really spins on hot start-up. I hope this helps others on line like it did me.
