Check the compression. Both cylinders should each be able to produce at least 140PSI of compression. If the compression is low, make sure the valve lash is set correctly. Insufficient valve tappet (valve lash) will cause valve leakage - and low compression. If the compression is good - then the carbs are likely clogged up. If the bike has been sitting for more than a few months, have them cleaned out.

It sounds as if you have dirt in your fuel line or some bad gas.
I would recommend draining your tank and cleaning it, then replace your fuel filter.
