Changing gears problem with gear change

SOURCE: gear change down sticky

clutch plates are sticking has nothing to do with lever replace your clutch plates

SOURCE: unable to change down gear. gear lever stays down

Well, first of all ofcourse find out how many gears you have, if you take it to a shop and they tell you you have "One down, four up"
It means starting from Neutral, you click down once for first gear, and from there you can click up to fifth.
Try finding an open area, gear up to 3rd or 4th then gear down a couple times.
Remember, you must be in gear 2 or higher to gear down.

The bike has a bent shift fork in the transmission. You describe the classic symptoms. The engine will have to come out of the frame. Then it gets flipped upside down, right and left side covers, shift shaft, and other components are removed, then the bottom half of the gearbox is removed. This allows access to the shift drum and shift forks. There are some special tools needed and I don't recommend a novice mechanic tackles the job. Below is a diagram of how the shift drum moves the shift forks left and right to make a slider gear engage different gears. Please rate my answer. Thanks.
