Excellent video Max. Found this very imformative. The only thing I would suggest to anyone attempting this same procedure would be to not use the needle nosed pliers to put the wrist clip in. It's possible to distort the clip unless you're really good with the pliers. An easier way is to lay the clip in the groove and use the little opening to get a small screw driver on it and pop it in. Cheers Man.
Take the timing chain and pull it up and over the tensioner guide and put a rubberband on it to hold it in place. This way you wont have to worry about slippin it through seperately. You can use a 4" hoseclamp to compress the rings so you can just slip the cylinder down and not fight with starting the rings.
hey gread vid 5*(sorry for the bad english) so i have a guestion is the piston and the cam that you installt for the 08 raptor too? all i found was only 07 is ther anything change from the 07 to 08 and how many power have you more with this?
what was the stuff you were you rubing inside the cylinder, and then you rubbed something on the bolts too. Was that just motor oil?

Does the engine have to be in any special position? IE: TDC, etc... Did you have to do any kind of 'break in' after installing the piston?

@Blackman691 TDC, Yes. I just rode mine like normal, so really no brake in.
