Hello guys, I recently ran into some trouble with the bike and I am hoping someone can guide me to figure out what I can do. The bike turns on goes into gear well but once I try to throttle it, it seems unresponsive to actually move the bike beyond 30kph. I've checked and adjusted the valves and everything seems in spec, and I even used a jack to keep the engine at TDC for both cylinders. I am just wondering if I am going to have actually open the top end and be surprised with something beyond my mechanical capabilities.
