Welcome on board Dave
The surging you describe around town can be reduced considerably with a few relatively inexpensive and simple mods. You are best becoming an XT660.com supporter as some information is only available to supporters, plus you will be able to access the “Ask Kev” section of the forum and get expert advice on particular technical issues.
Anyhow, here are some links to some useful stuff to get you started…
