I bought a 1988 katana 1100cc. it runs.
it cannot support a load though. it will move on flat gorund and has trouble idling for too long. i changed the oil which was pitch black, swapped the filter, dumped the old gas, and cleaned the carburators. when i go uphill, it sputters and dies with no power or torque. runs very rich too, with a heavy scent of gasoline.
BUT.
having looked through the manual, in the diaphragm end of the carbs, when i pulled them open, i had my long main springs, with the needle jets just sitting in them- when i saw this i couldnt see any way this would keep pressure on the needle, but thought i just didnt know what it was supposed to do.
Having looked at the manual, i see there is a jet needle stopper and mini spring that is supposed to sit atop the needle, and i presume the spring sits on top of that to make sure the needle is always protruding from the piston valve. As is, if i tilt the carburators back, and manually flip the piston valve up and down somewhat rapidly, the needle ascends into the valve piston and does not come back down without significant jiggling. i'm quite sure this is my problem with the bike sputtering and dying, but at the same time, the manual (gsx600f, mine is a gsx1100) has slight variations and i dont know if the part i'm going to look for even belongs in my carbs.
think this would be causing my lack of power and difficulty idling?
