<snip>With a modest 5 to 6 lbs of boost my FJR would be a lot more likeble to me. I'd have no problem handling or utilizing all of the speedometer. For a cost of about $4000 it would still be as cheap as a BMW 1200-GT. I made this post because I was wondering if anyone was aware of a practical application that would fit and work on an FJR.

First off, about 80% of the people I run into that want more power, don't use the power they have to begin with. Red line may be 9k, but the fuel cut is at 10k. If you're shifting early when you want power, you're throwing power away now.
Now, if you want a turbo, it's fairly easy to do. Buy a spare exhaust manifold and a small KKK turbo and get a flange welded to the manifold by a shop specializing in turbo work. Then you need a downpipe to mate back to the can(s) and an inlet pipe to route the compressed air to the intake. Toss in a filter for the turbo inlet and the plumbing is done. Not simple to solve some of those areas, but do-able.
Now you need to manage spark timing and fuel delivery. A simple rising rate aux. fuel pressure regulator might do for a start on th epre-'06 bikes, though not spiffy high tech.
I haven't groked the bike's system, but it probably uses a MAP sensor for air flow sensing, which may lend itself to boost, or replacement with a sensor capable of signaling for boost. This may allow the stock system to deal with a low boost turbo addition and send more fuel based on the increase in air flow/pressure. The stock injectors will likely handle more fuel delivery. Alternatively, a piggyback ECU to manage fuel and timing is not that hard and several potential candidates are available. Link, Tech III, etc. Stuffing them into the tight quarters may be the bigger problem.
I like power as much as the next guy, and have done a bunch of turbo system work on cars, but just don't see the idea of a turbo FJR as very appealing. Throttle induced oversteer in a turbo car is fun, and predictable in the right circumstances, but on a bike it might be a handfull.
Oh, and full use of the speedo has more to do with gearing than power I suspect.
