I got a '83 seca 400 and I just changed the oil and ran some seafoam through it to clean it out. However, when the bike starts up, the rpms will slowly fall until the engine stops. If I pull the throttle to get it to rev a bit, the engine will turn off. It is not until the engine is warm (which I keep the engine on by having the choke in for a few minutes) that I can pull the throttle and it revs fine.
I am thinking this is either a petcock issue (I have a vacuum; maybe the gas isnt going through the petcock as fast as it should be)
Perhaps a carb issue? (I have no idea how to clean the carbs)
Any thoughts? Thanks!
