Took it out today for an initial ride and all went well. I neither rode it like a grandpa nor like I stole it. 30 miles . Got cold on me so cut riding short.
Ran better at end then at beginning like every one has said. Rode through town then up on the highway to 6000rpm just cruising around. 1 smaller on the counter shaft sprocket, but will probably change back to stock once broke it. Power is about what you have all said. Didn't have any oil or coolant leaks either.
O Ring is not to be found unless it's sloshing around in engine. I'll see when changing oil out at 200 miles NZ. But that may be this spring with winter here.
I did notice right off it seemed to have a lag when rolling on throttle maybe 1/4-1/2 throttle. But that seemed to go away after riding it . Maybe computer adjusting to new top end? Engine did seem quieter with new top end.
I'm happy with it. If nothing else, new top end with a few more ponies down low to grunt with. rj
