Are you guys running the stock XB 1.0kw starters,, or the high torque 1.4kw starters ? I received the Renegade Wicked Start battery, and it is much better than the original battery, but there is still some compression bump.
I read previous posts about upgrading to the 1.4kw high torque starter. But there were several complaints about oil leaks. I called Rare Electrical,, and they have improved their starters with an O-Ring at the front bearing to prevent the leak. They sent me a pic of the update. I will also post this on one of the other starter threads.
