running rich on tick over running lean i think when rideing

[Usher4566]

If I leave my bike on tick over it runs rich fouling plugs but when I ride and do plug chop it runs lean .could this be caused by poor adjusted points?

What bike?
also, at what speeds do you notice its running lean?

I know its a bit of a ballache setting up the air/fuel mix on a bike that uses some sort of ram air while the bike is at a stand still.

At least check the air filter and replace if dirty.
