On the forum that shall remain namless *cough*kawaforums*cough* there is a jetting list, with everyones jetting/exhausts setups.
As for doing it yourself, there is also a DIY on there, have a read, get a workshop manual and worse comes to worse, trailer it to the shop if you fail!
Carbi vehicles are great to play with, unlike those horrible FI things 
I was scared of shimming, and the first time I did it, took me ages, second time I was done in 1/4 of the time with no help
