I am assured that transmissions often get worse in the first few hundred miles, and will be adjusted by the shop doing the 500 mile service. I would be checking levels, making sure the supposed lube was there. I am totally unfamiliar with the 5 speed, so cannot help you with it.
On occasion when I come to a stop the engine is still rev'd up. This has been happening since the 125 mile mark as best I can tell. All the throttle twisting, carb tapping I do has no effect. I did however notice that on all occasions if I cycle the choke on and off it will reset itself back down to normal idle. Experiences?
