have a 82 suzuki gs 550 with a 4 car setup. The bike runs fine in nuetral. The bike accelerates good excecpt at higher rpm(close to shift point) it boggs and doestn't want to go any fast. It does this in all gears. It has nothing to do with the tranny, i am suspecting fuel/ignition system. The bike accels fine when at a low rpm. Any lead would be great at this point, thanks

New fuel filter and plugs. I just put the carbs on after a through cleaning; jets and all including all ports.

This bogging will not let me get above 50mph!!!


I just bought the bike a while ago. It has ran this way from the beginning.

I recently got a new airfilter for it.

By the way, if forgot to mention, In neutal and when clutch is in I can open the throttle to Wide open without any hestitation. It seems it boggs only under a load at higher rpms.
it does bog when 3/4 wot and runs better the less throttle(1/2) i give it. The previos owner bought the bike from someone in Texas, I live in Nebraska. So that could be enough difference in altitude to require more fuel.
