loss of power in and out at full throttle

[98SPX]

i have a 1998 spx and when i go full throttle the engines seems to get power in and out kind of jerking but if i back off the throttle a bit its all fine?

Have you replaced the gray fuel lines? It sounds like it is carb related where as the carbs need a good cleaning and adjustment.

raves need cleaning and/or rectifier needs replacing.
