Personally I try not to slip the 900's dry clutch too much- it is a bit of a 'light switch' being either engaged or not but the hotter you get them by slipping the grabbier they get.

You soon get used to the technique though and my '97 bike is still on the original clutch at 30,000 miles although it is rather noisy as the basket is getting worn some.

As far as the popping about in traffic and such it could simply be it wanting to clear itself as it gets a bit hot or maybe a little air leak on the inlet rubbers or like mine did a few times before I renewed all the fuel hoses and the Vacuum tap and pump last year, the start of it going to vapour lock where it starves itself of fuel when it gets too hot.
