It will not damage the engine at all. All that will happen is that it will run richer, thus using more fuel. If you did it for thousands of miles you'd probably end up with more deposits in the engine/exhaust, but even that is easy to sort.
The 'worst case scenario' that I can think of is this. Your spark plugs become fouled because the motor ran too rich and the bike doesn't start. You would need to remove the spark plugs and clean them with a carb or brake cleaner and re-install them. Don't worry about your vehicle. It's fine.
