2010 crf 250 dilemas: crazy amount of oil finding its way into combustion chamber

[GetBlackLabelmx71]

Has anyone ran into any strange problems with the 2010 crf 250? I found out the hard way that Ordering "gasket kit a and "gasket kit b" from honda does not include oil seals! any way got the valve seals from honda and then used a aftermarket seal kit, only to find that from 2009 to 10 honda changed the countershaft seal size. any way the bike has all new seals,crank, cylinder, piston, rings, valves and seals springs etc. Brand new gaskets coppercoated and tourqued to spec! still seems to be burning alot of oil, seems like a big problem, im thinking cracked head or guide, but maybe its just something simple and ive made a mistake? only problem is ive profesionally built about 200 engines so. any way im open to suggestions cause the bike was a buddy deal and didnt pay right now i have all this time in it and cant afford to tinker with it any longer. any suggestions???

also combustion chamber passed a leak down test with flying colors!

*** correction counterbalance seal not counter shaft

The rings may have not seated.
What oil did you use during break in?
How did you break it in?
Is the motor running hot?
Burning oil or blowing it out?

why would you copper coat Honda gaskets? Probably the best gaskets on the planet.... Are your valve guides loose? All the new valve seals in the world wont help a sloppy valve guide
