The 668 already has a high performance motor, with a relatively sophisticated fuel injection system and a high state of overall engine tune.  There is always a fine balance that needs to be achieved between performance and reliability, so the path that any owner follows in the pursuit of performance should always be chosen carefully.

One factor that influences choices is the cost/benefit ratio.  If it requires spending large sums of money for a very small gain you may decide not to follow a particular path.

Performance improvements can be made to many different parts of the overall envelope, so an improvement in a particular area of the envelope may be of no real benefit to a rider who rarely, if ever, rides in that area.

Check out the combined wisdom and experience of other owners before making your own personal decisions.
