My friend has troubles setting up his Ktm's rear susp. At higher speeds when he hits the whoops rear wheels starts to bounce from side to side. At lower speeds there is no problem.. Does it need revalve or should he twist the clickers?
'98 was the first year with the PDS shock and they had some handling issues. Your friend may be able to get it to work ok by adjusting the compression and rebound but most people never could. If it has never been revalved he should consider it. MX-Tech has a low flow piston and new valving that makes it work the way it should. Well worth the money spent to have it handle the way it should.
