This will be a tough one, since your not providing substantial information. You need to elaborate a bit more. The 787cc XP was in 96 and 97, so my first wonder is how long has it been since the carbs were rebuilt. Then, is it still equipped with the grey Tempo fuel lines. You need to really give a bit more detail before someone can really jump in for you.

Clean and rebuild the carbs first, pay special attention to the low speed jet.

Depending on the model it should have a vacuum pulse fuel pump on the side of the carb(s), check the hose between the crank case and the pulse pump for condition/splits. you can also disconnect the hose and hit the starter with your thumb over the hose to check its working.

Did you ever get anything figured out on your ride? Just like everyone else said check your carbs/fuel pump, if that looks good check your rotary valve cover clearance, if the cover is getting worn you will have those same symtoms, you would have to get the cover machined to bring the clearance back to spec.
