If you are concerned with oil temperature the only thing that makes sense is to replace the air temp gauge, which is totally useless, with a oil temperature gauge. Not hard to do and there are gauges out there that are a relatively close match to the OEM gauges.
I know any number of people that are happy with this setup, it just doesn't make sense to me personally, because I pay no attention to gauges. When something is wrong, the bike will tell you, usually before the gauge actually registers it.
