I've been using a Powermaster mini-starter in my Bee ever since I went to TTI 2" headers probably 6-8 years ago, but from last fall into this year, I've been dealing with lazy, hot starts after driving the Bee. So far I've replaced the starter relay, voltage regulator, and negative cable from battery to engine block and the restarting issue is much better. Only thing left is the starter, but it's not making any of the telltale sounds of a bad starter. The cables to the starter are wrapped in thermal wrap and the starter has a heat blanket so I'm hoping that's heat protection. Initial timing is at 18 degrees, so I'm not overtimed.
For those using a Powermaster starter, have you had to replace it after a few years.
