I'm having a mechanical problem with my 250cc motorcycle. It has 5-gears, and all work smoothly but the 5th gear.
the 5th gear will only work/engage when I shift to it coming downhill on a roadway, from this point it will stay in 5th gear(at least that is what the speed I can achieve indicates) while I'm either continuing downhill or riding along a level surface.
Once I begin to climb an inclined roadway, my motorcycles mechanical system(transmission I believe) enters this unknown state where, though I'm set to be in 5th gear, my motorcycle can't even achieve top speeds of the 4th gear.
Some input to consider when producing a valid answer to my question:
- I've put +3500 miles on the bike, which was put on riding overt long-distances primarily in 5th gear.
- It's been about 3,000 miles since the last oil change, and once again, a majority of those miles where accumulated while riding in 5th gear.
