Greetings from Spain

I arrived here a couple of weeks ago and noticed a sudden oil consumption on the way. An oil consumption too big to be ignored. Luckily I got some good amigos here and they convinced me to take out the engine using their garage. So I did and I'm glad because a lot of soot (for sure) in the combustion chamber and now that everything is measured by a pro, it turned out that everything else is perfect except the oil rings! They don't seal properly. At first we thought it was the cylinder being oval but turned out it's the other way around. Also not much honing marks could be seen on the cylinder although it's about 7000 km old.

This is not a stock cylinder. It's the Off-The-Road's 104 mm kit accompanied with Carillo's piston and rings. Only about 7000 km ridden after the engine overhaul and the oil rings are ****ed while everything else is correct.

So does the jury here have any other theory for that except bad honing or manufacturing fault with the oil rings? If the mistake was by me, I wish not to repeat it.

Jami
