I hope you guys are right Roger and it's just oil temp. I'm anxious to hear your findings once you actually test this theory. <<snip>> > I have to chime in with John and Dave: I notice that my oil consumption increases in hot weather.
I never heard that one before. Sounds like maybe the way you hold your tongue might have something to do with it also. :-' <<snip>> >And as previously noted, the oil light goes on sooner when climbing a grade with a strong wind from the right. This tells me that oil is in fact getting out of the crankcase via the vent. Am I mistaken, isn't it just air pressure that's supposed to exit the crankcase via the vent? <<snip>> > For awhile I had the crankcase ventilator ducted to the atmosphere like in the old days rather than into the air intake. I did this on the outside chance that the intake was sucking too much oil vapor out of the sump thus increasing consumption. I still used about the same amount of oil, and it was making a mess on the side of the bike from the oil film being pumped out. Sounds like a makeshift solution that sacrifices power at low speeds. Something I personally wish the GTS had a little more of. <<snip>> > The biggest improvement I found was when I changed my rear sprocket to a 42 tooth. That keeps the revs down at elevated speeds, thus minimizing consumption. I can usually run a 24 hour rally without having to add oil. Yeah, I remember Dave mentioning this, but again it's just a makeshift solution. Having to carry all that extra oil on a trip when nobody else in the group does kinda pisses me off, not to mention that the catalytic converter is bound to be getting plugged. I have owned my bike since new and it has been treated very kindly - engine wise. I'm more that a little disappointed in Yam for this problem and want to find a permanent fix for it. <<snip>> > In addition, Dave and I have an idea for a remote oil reservoir to add oil without having to stop. > Roger
