Finally i've gotten my bike back together, polished laid out chrome here and there and I was riding for the first time today after I had changed the clutches and tapped a few bolt holes in the valve cover while the motor was out of the bike, checking the valves and making sure everything is on the up and up. I've noticed in 4th or 5th gears if I'm just cruising and hit it hard it will loose power and feel like it will rev back into power. First I was like dam that didn't feel right so I did it in 4th and same thing. No grinding gears no funny sounds, just a loss in power and bang it comes back, almost feels like i have pulled the clutch in a bit and let go? Someone have experience on this one?
