motorcycle reliablity, high mileage? Options

[Hanyo]

Whats consider to be high mileage on a sport bike? At what mileage should you expect a sport bike to get to?

I don't know about all that my friend carbs require more work (tuning, adjusting needles ect.)

FI are FAR superior to carb'd bikes, and much much more tunable.

Think GSXRs or even the Yamaha FZ1....the FI bikes will run circles around Carbs any given day of the week since they self adjust...or if you have a PC you can adjust it even more at the turn of a dial. Carbs are also more likely to be slower off the start as they aren't as consistent or frequently kept up with as an FI bike. (I've also never seen a carb'd stunt bike)

Carbs do require more tuning, but once they are set they end up being just as easy to work with as FI bikes. In most cases, people fawn over FI bikes because they feel they have more control via dynojet power commanders. You have the same amount of control over fuel levels in either, one is just a little bit easier to tune in a hurry. If you know how to tune carbs and FI, either will work.

The reason why you see FI bikes beat carb'd bikes is solely because of other mechanical advancements. For instance, newer gsxr 600s are weighing in at ~360lb. vs. the '97 is roughly ~415lb. That right there makes a difference.

If you compare the '98 to the '97 gsxr 750 (same bike, one is carbed, one is injected) you will see almost no difference in terms of performance. Once again, squids prefer carb'd bikes, and will usually go for the '97 instead.

Take a look at this video and take a look at the bikes being used, a vast majority of them are carb'd. Video That's not saying that all are, but a majority of them are.

The reasoning behind this is that when doing a wheelie, you want constant flow. With injectors, they are only putting in a certain amount, when you get on one wheel it's a little less smooth with the FI. The pulsating amounts of fuel creates a less stable wheelie. Once again, I'm NOT saying that you can't do it with an injected bike, just that carb'd bikes work better in different places.

The biggest improvement that FI bikes brought were fuel efficiency, and for that they are coveted.
