Wilsons Sandbox

I've just fitted a supertrapp IDS race pipe with 8 discs (it was on my DR650 like this). I have not yet fitted my dynojet kit and K&N. The bike starts hot or cold, idles fine and seems to rev out better. There is no apparent hesitation, should I put in a larger main jet or go for the stage 2 setup in the kit or leave it alone for now? I'll be happier when I can get some petrol. How I envy 650A models with their huge tanks...full of course! thanks for any help Van Nottingham UK
