Hey, i know longer have this problem. I got the rectifier replaced but i also keep my battery on tender at all times. So one of those two solved the problem.

Hello, I was having a very similar issue with my 2003 Hayabusa. It ended up being the ground wire going from the starter to the negative lead on the battery. Due to the placement of the starter, the wire is very close to the engine. In my case the wire was resting on the engine. When the engine would get hot it would heat up the wife, causing too much resistance for the battery to turn over the starter. I simply moved the wire so that it was no longer touching the engine and my hot starting problems have completely disappeared.
