Hey Ritchie, your controller works like a charm, I've noticed a big difference in the throttle and the bike seems to run better. I originally thought it was going to be a hassle mounting the toggle under the seat to switch it back and forth, but not an issue. I just have to lift the seat a couple of inches to switch it. I haven't checked the fuel mileage yet, so I can't report if it helps or not. We finally started cooling down here in South Central Washington, but we were having 100 degree highs with low's in the 50's. Going over the Cascades to Seattle tomorrow, so will see how she does.... So far so good and loving it. Thanks for making it available.
