We have now fitted an SWM 240, an SWM 280 and a Jumbo with OKO K-101s. This is a quick and easy fit for the 240s and 280s, only requiring a rubber boot to fit over the existing airbox boot, which we include in the kit. With the Jumbo, we sleeve the intake as well. Both power and throttle response are improved, making these already nice riders even better. The 240cc engine takes a 26mm K-101 and the 280cc and Jumbo engines take a 28mm K-101. Jetting varies slightly depending on the exhaust. If you use an FMF or other aftermarket silencer, it will jet slightly richer than the stock silencer, so we'll soon add that as an option when purchasing.
The OKO K-101 26mm carburetor kit for the SWM 240cc Trials comes as jetted on our test bike, but includes some extra jets for elevation differences. The float height has been set, the correct needle is provided with the clip set in the correct notch. Also included is the rubber airbox hose sleeve.
The OKO K-101 28mm carburetor kit for the SWM 280cc Trials comes as jetted on our test bike if you run an aftermarket silencer. Our test bike with the stock silencer took slightly smaller jets. The float height has been set, the correct needle is provided with the clip set in the correct notch. Also included is the rubber airbox hose sleeve.
