Bike is sputtering at mid to high revs

[Suzuki]

My Suzuki a100 keeps sputtering like it is running out of petrol at mid to high revs, but it is fine at low revs. If anyone could give me some ideas why, it would be great. Thanks

Timing could be off. Check spark plug. The fuel could be stale. The oil petrol mix could be wrong. Check the carb/manifold for any air leaks (it could be a fine crack that only lets air in under vacuum). Has the exhaust baffle collapsed?

Most common cause for that symptom is a sad spark plug.
