What a difference from my first test with a few tweaks and changes. Wanted to document it here for you guys. Absolutely stoked with the current setup! I think it will be unreal at sea level. I was riding probably around 6k' elevation in this video. Since the last test video, I've added a Brembo hydro clutch, changed the gearing to 12/50, changed the jetting, and just threw on a TSP high comp head for fun! I also went back to the FMF Fatty from the Gnarly and added in Sunoco race fuel. Still have the HITLIS in as well and that has made a massive difference in power delivery. I'll add links and details to some of these changes. Valentini who makes the clutch currently does not have a distributorship here in the states, I'm debating becoming that person since I find it to be such a crucial add on to the bike for myself. Want other people to have the ability to use it.
I still have two more bike build videos to throw together for you guys at least. Just wanted to share my test since it was fresh in my mind, and I was so stoked on it.
