Piston/cylinder clearance Wiseco?

Got an 650L that pump oil. I will do the valve seals and seat and want to know what cleanrance wiseco want for their 101mm piston? And also ring end gap?

Bike was bored a month before I buy it and I think the machinist went too far. Bike rolled maybe 3-4000km after that and top of piston/valve had so much carbon black sludge on them they looked like something coming out from a 350 chevy engine with 300 000km on it. Also had a big ridge of carbon on top of cylinder where the ring stops. Not normal after 3-4000km.
