[QUOTE="Boit, post: 165867, member: 19734"] Thanks for the info Michael. I have one of the first Mikuni's offered for the KLX that has the venturi bored by an aftermarket shop. They ruined it. This carb would be an excellent example of a shop that should NOT be doing this type of mod, plus what the consumer should be aware of. I was naive and assumed that this shop knew what they were doing. Oh well, that was years ago and this is now. I was just a few minutes ago inspecting the slide in the ruined carb and it shows very visible wear so it's probably not a good candidate as a replacement for my present carb. That leaves me with an option or two. If I stick with the Mikuni, this slide problem will resurface in the future. Another option is to fit an FCR carb. I have been extremely pleased with the low-end response that the Mikuni provided so I might have to sacrifice that asset for more high-end with the FCR. I prefer the Mikuni style of power because it complements the 6 speed tranny. I spent a lot of time dialing in this setup so it's pretty frustrating to encounter this problem. By the way, Yes, I'm very familiar with how the accelerator pump works. The plunger seized inside of the float bowl circuit on the present carb so I cannibalized from my bad one. The lesson here is to never leave fuel in a carb for extended periods of time. I should have known. [/QUOTE]
