I just did a run from home to work on the freeway, fairing is just enough to cut most of the buffeting. the windscreen was taller and cut 100%, this does about 80% so unless I am doing 1000 miles in a day at 80 mph it will do. Cuts 100% at 55-60 mph so its good. The volts never dropped below 14V on the meter with all the lights on the whole ride, and I let it idle for 5 mins and stayed above 14 with the lights all on so I think I am good, I did something to the stator when I had the engine out back in 2009 but not sure now what.
The fan didn't kick in though as it isn't hot enough here yet to need it. that will tell.
