Did you order the new combo that comes with the new 2087 pipe? That pipe will help you get better fuel mileage when compared to the 2045. If your going to try to use a JP pipe or something the chances of a 10 minute pit are not very good.
Also remember the heat gun is your friend. If you heat that thing up every time you start it up untill it no longer has any metal pinch it will last you a very long time.
That is only the case because they don't maintain the bearings the way they are supposed to. I have an MBX6 and lube the bearings after every other race day but i clean them out with WD40 after each race day through the holes in the hub carriers. I have timed my drive train after a quick rev of the motor and shut it off and it literally spins for 45+sec with the stock bearings.
But anyway, I have the Shark 10 which is practically the B11, with the 2045 pipe and can do 11:30 pit stops.
