with my AGB29 in stock form it ran great with the stock jetting when cold,
but crap when it's hot, it used to overheat and flame out and give me all kinds of troubles when it got really hot.
I changed to a 102.5 main jet, and adjusted the pilot jet (the screw on the side of the carb) and now it runs incredible when it's hot, but requires choke when it's cold until it heats up.
some people are using 105 main jets, depending where you are and what fuel your using this may be too rich, or may not be.
I am considering changing my pilot jet.. havn't decided what to yet,
as i seem to have to run the current pilot jet in too far to remove any hesitance.
I run BP Ultimate 98 only with a K&N Air Filter.
I would also suggest just buying a can of carby cleaner, (you can get it at supercheap, or even at the petrol station) dropping the carb off and taking off the bowl and giving everything a good clean, this might fix your problems.. I found alot of crap in my carby when I took it apart which was contributing to it running like crap.
