@@lamonzoscott2593 I have a 2017 RGU, which started life as a first year 107 M8. It had been assembled elsewhere (in Oregon)after top end warranty problems, with a 124 kit from FuelMoto. I wasn't confident in the build and as I passed by Moonshine on my way to Alabama, I stopped in and asked Aaron to listen to my concerns. Jamie, Mike, and Aaron immediately saw some things that needed attention. I slept in my trailer in the parking lot while they took everything apart, checked it, and reassembled the engine using their 492 cam, SE heads, 64mm TB and intake, Moonshine headpipe and mufflers, Power Commander, big injectors, probably something I'm forgetting. Dyno Tuned 133 hp 143 tq. Great for a street bike. Over 20,000 hard miles on it already and it kicks ass. Just turned 71,000 on the bike itself.
