Jerking at full throttle
So, I've got a Chinese 200cc enduro from a local brand that has a PZ30 carburetor that just behaves odd.
By now, I'm pretty sure it's a jetting problem, definitely not coil or plug. Basically, when you open the throttle past 75% the bike might suddenly "cut out" and starts to jerk pretty violently until you let go the throttle a little. It works perfectly fine on low and medium throttle and the spark plug is a nice brown color, so no doubt it's working fine here. I have no way to know how it's burning at full throttle because I can't drive it at full throttle for basically any period of time. So, any suggestions? Could it be too lean or too rich? I'm planning on getting some carb rebuild kits to mess around a little with the jetting. |
