nelson5847 Posted December 6, 2012 Report Share Posted December 6, 2012 Hi All, Recently started stripping front forks on sherpa t. First of all does anyone no what the small spring is for. The small spring is in a fewbits, where can i find new ones from and the plates they sit on? or is there an alternate suggestion? Cheers.

woody Posted December 7, 2012 Report Share Posted December 7, 2012 It's to cushion the rebound of the forks when they fully extend or 'top out' on rebound. If you pull your forks up hard without any oil in (or even with oil in, in the case of Bultacos...) the clunk you hear is the metal sleeve that's locked in place with a circlip in the botton of the chrome stanchion, comping into contact with the top of the damper rod. This is the impact that the spring softens. The plates they sit on, damping valve and seat, are what help control the oil flow to provide damping. No idea if you can get these parts new anymore, try Bultaco UK as mentioned above or: John Collins at JC Motorcycles Port Talbot Sammy Miller Alternatively, it may be worth looking out for a pair of scrap rusty forks on ebay for the innards, or for used parts, try: Ellastone Offroad breakers Wakefield Offroad have broken lots of trials bikes. You could also use damper rod parts from an Ossa as they are the same forks, the Ossa just has slightly different damping characteristics (better) You can use the damper rod assembly complete off an early Ossa with the shorter forks as they are the same length. Later Ossa forks ('76 on) are longer, so the rods may be longer too, can't remember. The individual parts, the springs, valve and seat, would be fine though.
