If I am in 4th just cruising and decide to get on it without downshifting it just feels like the bike is not going anywhere. Its tough to explain but when in 1st or 2nd any twist of the throttle is responsive. 4th just feels like a clutch slipping (bandit clutch so its not slipping). The bike does speed up but its not the same responsiveness. Is this normal or to be expected? I believe it only does this when doing a 4th gear pull. Thoughts?
