[QUOTE="2Wheels, post: 215882, member: 3804"] Ah that little calculation may require a bit more understanding than can be related in a forum post. You may want to research some fundamentals about what exactly you are attempting. Short answer is, the distance between the cam lobe and the valve bucket at top dead center must have a certain amount of clearance listed as specification in the manual. .015mm-.20mm for example. The shim you need will fill this gap appropriately as tested with slight drag of a feeler gauge. Measure the clearance you have versus the clearance you need to have, and size your shim accordingly. Now if you ask what is top dead center I'm calling motorcycle protection services on you to take it away to a foster home [/QUOTE]
