Thanks guys. Waiting to tear down until after four-stroke wars. I spoke with John at Racers Edge and he is one heck of a guy, but said they were focusing all there attention on the races. Worked great for me because I just put this thing back together and want to get in some ride time. After the races John said they normally have a 2 day turn around and I will send him the jug, head, and throttle body. I can't wait because this thing handles so much different, it will be easy to handle the extra power. I should have stretched this thing a long time ago.
