By no means scientific, I have two recent observations of oil consumption in my bike.
I told you guys earlier in the thread that i had just changed the oil after a winter's usage. The weekend after, I rode approx 50 miles of rocky, hilly terrain, almost all of it in low gear. I checked oil before the next weekend's ride and found that it had consumed the entire dipstick hashmark section of oil which is damn close to 200ml.
I topped up, and went for rides on Saturday and Sunday, both very similar....almost all of it in high gear, quicker trails, bunch of road running.....basically the opposite of the weekend before but this time closer to 100 miles over the two days. Zero oil consumed....at least no level difference on the stick.
Same Yamalube oil, ambient temps about the same, way different trail conditions and driving style. Not enough info to even guess if there's a correlation, but I will be paying more attention to details of my previous ride while checking oil level for the next one and keeping a log of events.
Anyone notice anything similar?
Buddy offered that seeing how the engine had been used in gennys, that maybe they are designed to operate at higher rpms and they pass less oil by the rings at those higher revs? Just spitballing of course.
