Today the engine is idling a bit quicker and then going back to the normal idle. She also has stalled a few times when I try to accelerate from the lights.
Reminding of the carby bike. This would happen and I would have to adjust carby. Anyone have a reason this is happening on  UCE?

Sticky Throttle cable? Throttle cable routing mucked up?  Throttle body return spring broken? Dirt in Butterfly in Throttle body?  Slightly loose Throttle mount (Manifold)?

That's what I got.

You might check the tightness of the bolts that hold the fuel injector throttle body to the manifold and the manifold to the cylinder.  A small leak there might cause the problem.

When new, the fuel injected UCE seems to search for the proper idle speed and I found that if I used the big brass idle adjustment screw in the top of the throttle body to reduce the idle speed that helped mine.
