[QUOTE="ossagp, post: 174603, member: 1650"] I am always glad to see a wet and oily power valve. So far I haven't seen one of those stick. The ones I see are always burned to a hard crust, but heck, maybe I will find a wet, well lubed one stuck someday too. The advice on setting the float is pretty solid as is running the recommended ratio. When you set the float, check your jet sizes and compare them to the stock suggested sizes. If they are more than two sizes smaller, you may want to be really careful after resetting the float, as the last owner may have "fixed" the high float level by going smaller on the jets. When you reset it (16mm is suggested for most Keihin carburetors that I know of) it may end up being too lean and that can cause piston failure. FYI the Kawasakis that Rick Carmichael rode had the floats set and reset at each event. Yours if it is typical may have 15 years on it. Free and easy to do. [/QUOTE]
