I've had a little recent experience wth the KOSO and OKO flat slide Keihin copies. They are quite good for the price. One 28 mm OKO had poor pilot circuit function. I removed the jet block from the body - 2 loctited screws - and tidied up the drillings and increased the chamfer size to align the idle and progression passages; problem solved.
