It's February, time for the annual dissect, clean and inspect ritual on the 85 100RS!!!!!
back story: mine since 1989, had 350 miles on her when i acquired it now has 202,000! previous owner was tall and had back issues so he couldn't sit comfortably in position required to ride the RS. He stored it in garage under cover and finally caved in to my unrelenting pressure to sell. installed new battery, added some fresh gas and it started right up (literally) i rode it home and have been its caretaker ever since. I do all my own maintenance and repairs, most of the components are still original it truly is a teutonic marvel.
this year is a major maintenance cycle as several of the intake manifolds were cracked as were a couple of the rubber bushings on intake plenum, side note: they are all original!
With this maintenance cycle will come spline lube, clean-up and adjust of clutch mechanism, intake/exhaust valve adjustment, replace original throttle cable with new unit, install new clutch cable and leave old one in place as a spare.
I am also going to install digital water temp and oil pressure gauges, have mechanical now but several years of vibration have caused needles to shake continuously while riding.
I cannot believe how clean the intake chamber and valve stems are, always run high-test from major supplier (exxon, chevron, etc).
PS: those expandable foam ear-plugs make excellent injector hole covers.
