Anyone running Koso or OKO flatslides?

[Redbird]

Does anyone have experience with the Koso or OKO flatslide carbs?
The Koso's look like PWK knockoffs at 1/2 the price, and the OKO's look like Koso knockoffs at 1/2 their price. I've seen decent reviews on the Koso, but nothing on the OKO. I remember reading somewhere a while back that the Koso will take PWK parts, but needed some sort of mod to the air screw. I can't seem to find that review now though.

I have an OKO 26mm and it seems like a decent carb, I am yet to tune it so I can't give you an in depth review other that the first bike I had it on ran very well with it and power came on quick.

i have been sent some a few times a year to try by various distributiors

they are junk as far as i am concerned crudley made and cast

quite a number of them the brass fuel nipple can pull right out of the body of the carb

and then fuel leaks all over the place

they also dont have a good selection of parts for them like slides with different cutaways

life gets worse when you try yo use them in pairs or more as no 2 of them flow or run the same

even the jets are not quite perfect copies
