Wr250 engine woes

[1-600-matt]

So it's a 2005 and in about 200 miles of green lane pootling used all but about 100ml of its oil!!

Two questions...

So engine out to find slightly worn everything!! Cams are worn on the journal but may stick them back in until it dies as I really don't fancy forking out for a head. Valve clearances non-existent on two of the inlets and the shims are at min thickness so needs valve seats... Will I get away with the original valves with new seats?

Cylinder bore is fairly worn in places and a bit scored, but not very bad, rings are well worn, plus the ring gaps were all very close to being aligned!! Piston is a vertex and doesn't look too bad, but gonna bore the cylinder and re-coat and give it a stock piston and ring set. Will the stock piston make any noticeable difference compared to the vertex? Apart from hopefully not burning all it's oil inside a couple of rides!!!

Impossible to say without inspecting it in person.

I haven't even got the valves out of the head yet, but would titanium valves not take a lot of stick? I have my fingers crossed that the valves have survived!
