How do I assess the severity of wear on my T160's slides?
Couple of years ago, I asked John Healy what the minimum body-slide clearance should be. He replied no less than 0.0035"-0.004"
I;m used to 900 series carbs and even when new, its possible to move the slides back & forth by hand a bit when the throttle's shut or part-open.
With respect, that isn't a valid assessment, if only because neither bodies nor slides wear evenly - on the body, the most wear occurs just above the venturi on the engine side; on the slide, the most wear also occurs on the engine side but between about 1/4 and 3/4 the way up or down.
I don;t want to put it back together only to find I should have fitted new slides - but I don't want to spend good money on 3 new slides unless I have to
While you can assess slide wear with micrometer or calipers, bodies need bore gauges (and someone who knows how to use them?). Because my bikes have a lot of special bits on them, I make a point of knowing at least one (sometimes retired) engineer or machinist near wherever I live, with both special tools and knowledge ...
By the end of this rebuild, if your greatest unnecessary expense was three new slides when you didn't "have to", treat your guardian angel to champagne and flowers ...
