[QUOTE="Martyn Goodwin, post: 104200, member: 2433"] From OVR 33: Often one reads about the need to “file” the lead tooth on a Kick Starter quadrant to avoid the dreaded “locking” of the kick starter. Attempting to force the kick starter once locked may result in damage to the kick start shaft, the kick start quadrant, the driven pinion, the rider’s foot or the rider’s leg – and any one or any combination of damaged items is possible. Once the kick starter becomes locked the accepted release technique is to engage a gear then rock the bike back n forth till the kick starter becomes free, then gearbox back into neutral and try the kick starter again. The attached picture is a close up of the lead in tooth on one quadrant superimposed over another quadrant clearly showing how it needs to be shaped. Note that its top surface slopes slightly towards the valley of the first “full” tooth. In order to provide the best opportunity for smooth engagement between the kick start quadrant and the kick start driven pinion it is advisable to polish the lead in tooth, especially its upper surface. There is also real benefit to be gained if the tip of each tooth on the engaged pinion is also polished. [ATTACH type="full" alt="25795"]25795[/ATTACH] [/QUOTE]
