Steve, from what I'm reading I'd say the best money you could spend would be on a day at the California Superbike School, where you'll get taken completely back to basics to learn how and why the bike does what it does, and how you can get it to do what you want it to - not cheap, but more than worth it for the understanding and confidence that you'll gain from it, probably the best £350-odd you'll ever spend on biking...
