So I bought my '88 K75S in September and it has been on a buddy's lift ever since. The drive splines were shot and I sent them to Bruno in Canada. Should have them back next week.
So, in the mean time we have flushed and replaced the coolant, replaced the fuel filter and fuel pump damper, sent the instrument cluster to Austin, TX to have the odometer repaired, and then replaced the instrument cluster and fairing. The back of the bike is still all apart.
So tonight we put the gas back in the tank and cranked it up and let it run for quite a while. Everything is looking good. Then I drain the oil, replace the filter, and add four quarts of oil. When we cranked it back up, the oil pressure light stayed on, even after a minute.
Did I break something during the change? The light was not on before the oil change.
