Making sure I get this entirely right:
The head gasket is rooted, so is the piston and barrel...but no damage to the head/ valves/ seats etc. at all? Yep, thats what they're saying.
"Stuffed" meaning exactly what? Pre-detonation dents to top of piston and sleeve as per pictures.
What are the rings like (broken? one/ all?) Wild guess here, I bet not pulled down that far.
If broken or fractured, any chafing/"re-surfacing" of the lip?
Any debris in the bore?
Filings/ debris in oil?
Burn-marks/pitting or hole in piston/crack or split in the barrel?
Was the airbox dirty BEFORE the PodMod was done? Wasn't perfect but equally not bad at all. Done around about 2400km with less than 200km of dirt 90km of this dirt was in a little dust on fire trails playing with some enduro bikes.
Some good questions there Glitch. I can only assume that they haven't pulled the barrel yet, maybe pending orders from PFG, I dunno.
I thought that a lean running engine would stuff valves or melt through the pistons.
I just phoned the workshop manager, he doesn't even know if the barrel has been pulled. Head valves and seats appear perfectly fine. Told me again that fitting a power commander and dyno tuning is highly recommended by the importer's technician to prevent this damage in the near future. He may get back to me with more detail of piston, rings, barrel. Wait and see. I am currently a little disappointed with this guy right now. Just remembering also that I had to take the bike to a radiator guy for a second opinion on the diagnosis.
BTW your parcel has been posted glitch!
Cheers,
