I appreciate your reply,
I sort of wondered if similar year R1s had this issue. I have owned the bike for about seven years and I bought it with low miles from a friend who was the original owner.
I presently own three bikes and have owned multiple motorcycles over the past 30 years. I have always changed my own oil, so when the oil light recently came on for the first time, I was shocked and immediately pulled over and turned the engine off. I was puzzled to see that the oil level looked fine. After several minutes when I finally restarted the bike, the oil light was off. I immediately rode home and after several hours checked the oil level again and it looked fine. So I topped it off on the high side just in case.
However, I still get the same behavior. At first start and at idle, the light does not come on. But at higher RPMs, the light comes on. If I pull in the clutch and coast, the light goes off. The if I resume speed (say 75 mph) after about 5 minutes, the light comes on again until I pull in the cluch and coast some more.
Any thoughts? For early model R1s that had sensor issues, did replacing the sensor fix the issue? And are they fairly easy to change?
I have never replaced the Switch or the Relay. I remember when the 98 models came out that people where having a fit about the oil light coming on while riding. Even some magazines commented on the problem, but where informed by Yamaha that nothing was wrong and that the light may come on from time to time.
On my 2000 the oil light would come on from time to time while just normal riding down the road at 55-80mph. It only stayed on for short periods of time though. No more than a minute then would go back out. I know of a couple of other owners with early models that had the same problem, but they never did anything about it other than reporting it to Yamaha.
Your case seems a little different though since you have not had the problem for several years and has just recently started. If you have a service manual, you can test the Switch and the Relay. If you don't have a manual, send me a PM, and I will hook you up with one.
The procedure is on page 8-42. I would check the Oil Level Relay first since is should be easily accessible (left side under the riders seat) The Oil Level Switch is also on the left side, but I believe you will have to drop the oil pan to get to it so that would be much more involved.
