Completed surgery on mine about an hour ago. I used a 1/2" chuck, 5 amp drill. It was a 3 hour tour including cool down time for the drill motor. The wife got pissed, but the refrig did help some. Don't leave it in too long or condensation will build up on the brushes and it won't run. The drill motor got really hot, let some smoke out it a couple of times, but that stench probably needed to get out anyway. In the end the drill was still going round and round when I broke through. Reflashed, with the map Jim mentioned and fired up the ride. Sounds RIGHT, finally! The 2" cores are good for me. I will install the SE Air Breather tomorrow night and take er for a ride.....
Work sure is getting in the way of these higher priorities! And yeah, FTC !! You'd think they built these bikes for a bunch of environmental wackos.
