82 kz550 ltd. Stock air box. Stock pipes. i just did a carb tune. it idles like a brand new bike(1000 rpm). it rev quickly under NO LOAD like a new bike. when i ride it and get throttle slowly it does just fine. Here is the problem, when i dump the throttle wide open really quick, the bike boggs down and sputters. CAn anyone help me?
Depends on how quickly you are going wide open. That bike uses a manual slide carburetor. You can't turn the throttle as fast as possible, from idle, without a bog on that type of carb. It needs to be rolled gradually as the RPMs increase.
From idle to full throttle should take .5 to 1 second in neutral. If you take 1 second to go from idle (1200 to 1300 RPM) to full throttle (in neutral), and it bogs noticeably or backfires or stumbles, you probably have a problem.
You should be able to do it in about half a second, if you start slowly and finish fast.
In first gear it takes a little longer... maybe between 1 and 2 seconds.
