Switch the carbs from side to side and see if the problem follows the carb or stays with that cylider. On stock carbs you will have to cap off the bosses that the choke tube goes between. Or do a leak down test like was suggested and that will tell you if you have an air leak for sure.

Are you sure the choke cross-over tube is connected? I left mine off once & it acted like what you are describing. I had to swallow my pride & admit I overlooked what should have been obvious.

I have been able to start my red bike without the crossover tube on several occasions. Beer or Yeager was usually involved though. :confused:

Check you wiring harness that comes from the CDI on the rt aft side and make sure it has'nt melted to your pipe.

new wire harness should i just buy complete new topend gasket set because the guy who put it together the first time did not torq priperly then i had it retoqed properly but maybe it blew a base gasket
