maybe u should change your rollers as it sounds like they are to ligth
u see the ligther the rollers are the more the engine will rev up before it will start picking up speed
so that with the type of rollers you have when you come under 5000 rev the rollers disengage if u know what i mean
(its a bit confusing to understand)
