[QUOTE="charismaticmegafauna, post: 199877, member: 665"] + 1 -- RTSR1/FJR Not entirely accurate -- altho I'm not aware of any slotted aftermarket sprockets, some may be available (or, you could do it yourself). Or extra bolt holes could be made at 'partial key-way' positions -- ala old Triumph twins. If you know what you're doing and know where you want to go (You become the engineer) the DOHC set-up with chain & sprocket drive offers unlimited possibilities for cam timing.Also, I think one of the not so beneficial side-effects of the automatic tensioner is that it's often just tightening the hell out of the chain (often creating a whining sound) and, altho not promoting wear, does ensure that all slack is always in one direction. That slack, especially as it accumulates over time, does change the cam timing. I'm in complete agreement and subscribe to the "go -- no go" method. A min-spec feeler gauge must "go" and an out-of-spec one "not go". [/QUOTE]
