If i wrap the throttle back to go as fast as i can the rev range shoots smoothly to 10k then bogs a bit then shoots again to 12k then bogs then shoots again to 14k, like a kangaroo lol
also my top end is supposed to be around 145mph for the spec of my bike, but it bogs that much in the powerband between 12-14k i cant get over 110mph

Personally i think its either taking in too much air? or the carbs may need balancing? but im not expert on 4strokes
any suggestion or help would be appreciated thank you!
