Reversing

When reversing or rolling back my DL125 in neutral at a certain rotation of the wheel it feels like it goes into gear (it does not actually go into gear) making it difficult to move, it takes abit of effort and then it will free wheel again till it reaches that point again. Even with the clutch in its hard to push backwards any ideas.

Cheers Des

Could you be hitting a high spot on the brake shoe or oval hub..?

Are your panels on or off?

That's an interesting one Des.

Are you sure that the problem is related to the rotation of the wheel? Is it the front or rear wheel? Have you tried propping-up the scooter and rotating the wheels by hand?

If the problem is related to the brakes, then the wheel will "seize-up" at the same place everytime (put a bit of chalk on the tyre to mark the spot).

If the problem is related to the drive chain, then it is less likely that the wheel will stop at the same place. Spin the wheel forwards at least 10 times before rolling it backwards and again, use chalk to mark the tyre.

Have a play and report back, though I suspect someone will come yup with the answer very shortly.

I only ask as it could be your panel clips hitting the tyre, if it is just cut them down so they don't

Try wheeling it backwards with the clutch pulled in.
If having the clutch pulled in cures it then it is a badly adjusted kickstart mechanism.
Whats happening is the kickstart teeth are engaging the teeth on the first gear cog and turning the engine in reverse,the tight spot is the piston turning over the top dead center point.
Had this same problem with a mates scoot recently.
I was doing the timing for him and and using the positive stop method to determine TDC,the flywheel would turn freely one way but not the other.

Having said that I'm now wondering if its right because the gear selector should move freely between the first and second gears.
Pulling the clutch in deffo allowed it to turn free though
