Very true. My '04RT took a couple thousand miles before the rings seated and oil consumption was high at about one quart per thousand miles. During this period of high oil consumption I could hear some pinging from the engine which was no doubt caused by carbon build up. Had a '79 R100T that original piston rings never did seat. Had to have bores ball honed and new rings installed which corrected the problem. Pinging was unbelievable as was the hard carbon build up on the piston heads. Wouldn't recommend ball honing an oilhead with the nikasil cylinder liner.
A lot of carbon buildup in Oilheads is can be attributed to oil consumption from what I have observed.
The ones that consume larger amounts of oil have higher buildup.
My own has very little carbon (borescope inspection) with a consumption rate of 100ml/1000km.
The real oil slurpers have lots of buildup.
