Jing Hua carbi worth keeping?

[tim_]

ok so i brought a bike from a mate and it had a 150 ducar engine in it and was running jing hua carbi.. it says its made in japan but i dont know if its a knock off or not.. also the slide seems to be very narrow... i will be throwing away the engine but im unsure if i should keep the carbi or not so if anyone knows about these would be a great help...


p.s i have searched this but no one seems to have requested a review..
