clean your carb
Is your bike is running ok once you get it started (no stuttering or surgeing)?
I do think you need to pull your carbs and clean them. Might very well be that you have some build up inside. Specially if the bike have been left standing with petrol in the carbs for a longer period at some point, if your pilotjet is clogging up your bike will be a pig to start and it will probably be quite weak on idel ( has a tendancy to cut out)
Pull carbs a apart and clean everything, when you put them back together set everything up according to the manual (chek needel position,what size jets are in there? opening of secund stage etc) then you get a good idea where to start makeing adjustments
Places to be and things to do, see you all out there!!
