Rob, looks like we're headed down the same path. I've been holding off buying an extra clutch and throttle cable until I sort out the riser issue. I'd also like to have an extra set for a XC trip coming up: The slave cylinder seal went on the clutch of my 640 one time and I ended up at a drug store buying mineral oil to get the clutch working again, so I'm now into belt and suspenders when it comes to that stuff. Thanks for all the work you're doing.
