Title: double check
Post by: captaindonutbikes on June 27, 2010, 01:01:26 PM

new exhaust valves in and head back on all timed up but still not firing. sparks on every cylinder.

the fuel feed on the cb550 k3 carbs is the larger of the two ?

just trying to eliminate any stupid faults

cant see what the problem is now ?  >:(

I'd spray a light mist of easy start or butane or carb cleaner by aircleaner and give it a whirl, if it fires up then you at least know it's down to fuel. I've found the k3 carbs are a right swine for starting, try a gentle tap with a small hammer or screwdriver handle against the carbs as floats have been known to stick closed and you may well find a bit of choke will be needed even in summer, my k3 always demanded choke. on the plus side k3 carbs are more economical than the rest of the range.
