I am a new gsf400 bandit owner and I am having souch trouble getting it running. I bought 2 bandits one was a complete bike with a title except for missing an engine, the other bike was a complete parts bike. I tranferred the engine from the parts bike to the bike with the title. It has good spark at all four cylinders, new spark plugs, cylinder #1 has 120psi compression, #2 has 125psi compression, #3 has 75psi compression and #4 has 140psi compression. It is firing on all four cylinders. The problem seems to be its not getting gas from the carbs into the engine. Gas is getting to the bottom of the carbs. I have cleaned and cleaned these carbs over and over again, i have replaced new o rings, the jets are in good shape, it has new floats. The bike will run when gas is squirted through the carbs for a split second. The diaphrams have no tears, and are in very good shape, they spring up like tUhey should. The carbs literally look brand new i have cleaned every little tunnel and there seems to be no clogs anywhere. The petcock works flawless, the gas tank has been completely cleaned inside and no signs of rust.. It looks like a new tank. :banghead:Am i missing something? I want to ride this thing so bad. If anyone has any ideas I will really appreciate it. Thanks..
