Re: bad fuel millage on road bike build?
As other have said, your mileage doesn't sound too far off from where it could/should be.
1. Newer engines will consume more fuel mix until the rings fully seat into the cylinder bore.
2. Tuning the carb is pretty much mandatory.
3. The stock plug and plug wire in the kits are garbage and could lead to fuel waste and inefficient combustion.
4. I ride my bike at WOT frequently, which of course will lead to more fuel consumption than if you were just putting around slowly. Something to consider.
I wouldn't worry about it!
