Is the line clear all the way from the bottom of the Gas Tank to the Carbs? The very first time I had mine off, everything was fine when I put them back on, UNTIL I tried to open it up. The Carbs where opening against the top of the T, on the right side, cutting off the Fuel when the Carbs where wide open. Everything looked great, ran fine, until I cranked it. If the Line still does it when you switch sides, I would think it would be a simular problem? Try running a long Fuel line along the outside of the bike, right to the Carbs, and see what happens. If that solves the problem, then the problem is in the Fuel Line. If it doesn't solve the problem, then atleast you know it's not the Fuel Line. Do you have the Fuel Line running back UP alittle somewhere may-be too? If so, it would still get Fuel, just not has much as it should. Sounds like hopefully something simple.
