To make a long story short, stripped the quad to the frame for a total rebuild over the passed week. Now I'm working on the engine.
I took everything apart the way the service manual tells me to, and I have a few questions:
First, my piston has about 25 hours on it. Is it suppose to have the black in the middle like it does? (Also, if anyone sees any wear that looks abnormal please let me know)
Second, the intake boot has 3 bolts holding it on, I cannot get the the bottom one with a socket, and my little 8mm wrench keeps slipping, any advise?
Third, I'm having a hard time getting the bottom of the jug off. The bolts are REALLY hard to turn. I am only using a 12" ratchet. Does anyone have any tips? Maybe heating them would help? (I'm talking about where the ratchet is in the pictures)
Fourth and finally, the quad has a Hotcam in it. I was told it was a Stage 1, however I have not had a chance to confirm this until now. It says"

Can anyone tell me what this means or what stage it is? Also, a friend of mine wants to buy the cam for his Ex build. He is new to 400exs and I wouldn't want to give him anything that was defective at all. So can anyone tell by the pictures if they cam is in good condition or not?
Thanks for the help.
