oookay........ Problem was the oil feed in the cylinderhead was closed. RockerArm ceased because of the lack of oil and kept pusing the velves down and the piston came up and hit it . Head cracked on the 3rd chamber, piston got beaten up badly.

Took the head in for some welding, skimmed the piston and fitted new velves. Started up fine... BUT the bottom back breather , breathes smoke and alot. Took it for a spin and no smoke come's out of the exuase. but when I rev it up to 7000 + it smokes up the whole cabin .

Now I went and talked to a few people and they said I should close up the breather and that it is normal for the motor ? Any comments? i'm so disgusted with this project.

Thanks
