I'm having a wierd problem. My KZ550 is starting to bog down sometimes, and I can really feel it when it wants to go. It'll just take off then go back to bogged down mode. So I let it sit over night to decide what it wants to do.
This morning I started it up, let it run for a couple of minutes and shut it down. Then I felt the heat coming of the headers. All were hot except cylinder one. I checked for a spark, and its got a good spark. So then I figure its a carb problem, so I put some Sea Foam carb cleaner in it and start it back up. It sounds horrible, sputtering, bogging, and just barely idling. Then I feel for heat again and this time 1 and 4 are hot, but 2 and 3 are cool. I let it sit for a while and tried to think it out. Then I went back out in the evening and started it up again and VVVRRROOOOOMMMMM it really started up! All cylinders heated up this time(I've got a burned index finger to prove it).
So I guess my question is when do you decide to rebuild and tune your carbs? And is it really as easy as everyone says it is?
