blimey thats a bit nasty! i sold my last thai 2012 on 13000km so no issues with that 1. ill let you know later on this year as i rack up the kms on the 1 i have now. did this bike have a pipe on it? i dont know anyone who remaps bikes in thailand after fitting a pipe. it might have an effect on fueling.

That's a good one, might be a bad batch of keepers... saw that years back on some CG125's.

Of course I'm generalizing from a single example here, but everyone does that. At least I do.

this particular bike is fully standard..well actually most of 'them' are in standard condition..

how many bad owners can there be? i mean if its just one or two cases then users wouldnt give a heck..and most of them claim to maintain their bike well..and plus the valve broke during low-medium speed cruising..

a victim, yellow black 2012 versys, had his valve blown at 130kmj..

another one, er6f 2012, 'it' happened at just 70kmj..

only a case that i came across where sunrock kawasaki (sole importer) replaces one to one er6f to his damaged bike..

all on low milage..

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.

A valve keeper is a small piece of metal used to hold the valve in place... If they fail the valve drops.

This doesn't look like a 'regular' issue... how did all that crap get in there??

That's debris from one of the valves coming down on the piston.
