Jetting: From 48/165 to current 45/168; what a huge difference, minimal deceleration backfire, strong mid, minimal bogging. I think I need to play with the air screw a bit, but overall very pleased. Heat: With the change in jetting, I think Gray mentioned it may run cooler? Obviously, the temps are dropping, Come on Fall/Winter!!! But, the bike seems to be running cooler. It was a fire breathing dragon before! Drive: From Pro Taper (stock gearing) and DID ERT2 to Tag (still stock) and DID ERV3 - Nice transfer of power to rear wheel, drive is very smooth. Obviously don't have feedback on wearability yet. How far should the axle blocks go back? It looks like it needs it's first adjustment, but I noticed with the YZ they lay back far in the swingarm; if you take it up one (1-1/2) more link it gets really short on the swingarm:confused: no middle ground here.
