1978 KZ400B1 carburetors need adjusting.

I'm looking for someone who can rebuild/adjust the carbs on my all original KZ 400. I can deliver it. Need someone who knows what they're doing paid a shop to do the work and still not right. I'm in Defiance, Ohio

Check out this web site. wgcar.com. This could be one option to get the carbs right, it you would have to remove and replace them yourself.
