Ok, so I took the cylinder in to my triumph/Yamaha dealership today(which is awesome for a dealership). The guy at the counter took a look and said he could tell that there was a lot of dirt in the oil. I showed him the pictures of the metal shavings in the filter and housing And he said to check the connecting rod for vertical play, well, that was my next question. It has quite a bit of vertical play. So it looks like ii will be splitting the case and replacing a connecting rod bearing and who knows what else. Any tips or advice for my future journey? I'm thinking of a .040 over bore since the price for pistons are the same (maybe namura), new rod and bearing (not sure what brand, haven't looked), probably just do new valves and seals. Either way, it is going to be a long project for me, not what I was hoping, but want to do it right.
