This case happen for while in thailand. many of them.
I spot same thing from case, the oil burning problems.
when cruising for long trip with high rev, can be the issue for kawa twin 650.
For mine, happen the same issue as this but not this bad at 47000km on it. Oil burning till red engine oil shown.
When I go for a trip, I always have spare 1Ltr of oil with me.
