2009 675r I just bought the bike today after eying it for a while. The guy was decent and doing business was a pleasure. I do my inspection,. The bike is bone stock with the exception of ss lines and a gp shifter. Aesthetically in great condition for her age, tires were less then 2 years old and almost 100% all the seals were good, suspension felt right, everything was tight and there. Turn the ignition, pre check is good,but when I cranked the motor, the oil pressure light stayed on in the cluster. Turned the bike off and checked the oil, it was clean and topped off. I asked him about it, he said it came on last fall. So now I'm worried. I ask if I can start it again, he says sure. Crank it again, no noises, knocks or rattles, other than the tensioner chain faint clicking.... But still, OPL. I take a few minutes to try and look on the internet, and I find it's pretty commonly the sensor switch. So I figure I'll test ride it, if the bearings seize on the test ride, it's still his bike. The bike ran incredibly smoothly and was feeling pretty confident that it was just the sensor based on the way the bike performed. The only thing that came to mind as we loaded the bike on my truck was the ramps he was using to load into and off off his. The bike ran the ramp at almost 45° and pivoted on the oil pan just to get it up into the bed. But after a two hour ride home, the OPL is still on. Any help would be amazing, since I'm now feeling like I made a huge mistake, now that the adrenalin of being I front of a new and available bike has washed away, and I'm left with a bike I know very little about. Thanks again.
