Yamaha XJ550 Acceleration Problem, Carbs?

Hi evan,

So I believe im having some problems with my carbs. When I accelerate a little harder the bike seems to gargle, then pick up. Would this be a mixture problem? or possibly the floats being all wacky? haha im not too sure. tongue

I just looked at all the plugs and cylinders 1 and 2 are a nice golden brown while 3 and 4 are sooty. that makes me believe its the mixture on those two carbs.

If you could let me know what you think and what I can do to fix this problem, it would be greatly appreciated.


It could just be sticky floats allowing the bowls to fill up too high. Pretty common problem that results with the cylinders being flooded with fuel.

Has it always run like that?

Time to yank the carbs and have a look!
