I am building up an older Schwinn cantilever frame with a 98cc Lifan engine and I have bought a pair of Suzuki K10 hydraulic motorcycle forks to use on this build. I know that a standard bicycle axle is too short by at least 2". Can anyone recommend where I can get a 3/8 axle about 2-3" longer than a standard front bicycle axle? Using Worksman front wheel with drum brake, so it has to be 3/8 to thread on to my cones. Thanks.
