Alright so my dumbass just realized I ran probably two tanks of premix that was at a ratio of around 85:1 through my KDX. How much damage have I done? How long until that thing is toast?
I really doubt you hurt it the least little bit. On oil injected bikes you run at that ratio all the time. It's only at WOT that the mixture gets near the normal premix ratios. That's the only time you really need it. So, unless you spent your entire ride at full throttle, it's unlikely anything bad happened.
