Why Purchase our Genuine OKO?
Our Genuine Taiwanese OKO carburetors are distinguished by certain design, quality and finish features. We acknowledge the market has been flooded with cheap fake Chinese copies of our product and these copies use inferior cast alloys, contain design flaws in the jet circuits and are known to be impossible to tune. To the untrained eye, its not easy to spot the difference. The fake OKO is also sold in some bore sizes (32mm+) that genuine OKOs are not available in. We note that in these 'hybrid' sizes, the alloy casting has been distorted well beyond the original design and we often receive reports regarding their inability to be tuned due to internal air leaks and/or erratic fuel metering. Jets are reported to be unmarked and other parts are a mixed bag from different types of carbs. We are committed to quality and brand recognition and assure you our products are the genuine item and as such we offer a full factory warranty.
