    Old thread... decided best I bring it back as I now own this bike. Has been sitting for some time. Front caliber is dragging. Is there a preferred rebuild kit or even better, replacement caliper I should source? Here in Canada.... Understood it would probably have to come from Europe or Asia. Would like to replace the fuel filter as well. Can not seem to locate one?

    That's why I won't date good looking fuses nowadays, they just leave you feeling flat by the end

    Thanks! There on the way... Have carbs off and somewhat apart. Quite the backyarding happened in there! Needle caps for instance... Two of them are actually home made drilled out screws! Decided to redo them all. New float needle and seats, new kit from Litetek etc etc.. Will be a while waiting for parts.

    What do SS and FP stand for?I am assuming SideStand for SS, but not sure of FP. Are these lockout switches? If so, how would I trick them into letting the engine run? I am using the engine in a Kart with total-loss battery supply to run the engine (no alternator) and a simple racing wiring loom. Does the neutral-indicator lockout affect the ECU?

    Speculation - SS is likely side stand, it makes sense

    Don't quote me on this, but I recall that the clutch switch let's the engine start in gear, but the side stand switch prevents it starting in gear, so the neutral gear position switch in conjunction with the side stand switch prevents starting

    I don't have access to my bike to check the side stand switch
