KZ650 running lean or air leaking in

Postby Nealmeal2000 » Tue Sep 26, 2017 7:42 pm

I joined up after reading someone telling all about carbs and how the hotter the engine gets needing a richer mixture ,just had to throw a comment its a cold engine that likes to be rich- have a kz650 thats driving me nuts with 33mm amals somehow getting air racing up to 4000 rpm with the slides closed tight so my wild guess is the choke passage somehow letting air by even though ive looked and see nothing wrong the rubber boots are fine just driving me nuts thanks-Sherwood

In the past I’ve heard of folks spraying WD-40 around the outside of the carburetor to find leaks.
