XT660X to XT700X conversion

Well, tonight the motor came out & there is good & bad news.

The good news I will be able to make the Raptor barrel fit. The bad news it is not a straight fit on kit.

1> XT casings are 2mm smaller then the Raptor barrel, I will machine out the casing 2mm.

2> The outer 6mm hole on the raptor barrel on the cam chain side is 4.5mm out to the casing, I will mill out the holes on the Raptor barrel to line up the 6mm bolts on the crank case.

3> The raptor barrel will need a semi-circle cut into the sleave on clutch side, it is for the crank case breather.

4> The back edge of the raptor barrel will need a 1mm chamfer cut into the sleave to clear the balancer shaft.

5> The outer edges of the XT head will need to be blended to the edge of the raptor barrel, by 1mm.

6>The raptor stage 1 cam is not a straight bolt on cam, the only thing that fits from the XT cam to the Raptor cam is the pin that pushes on the rocker roller.

Otherwise you need the decompressioner, decompressioner pin & raptor sprocket, luckily freez gave me a heads up & I ordered these extra parts from the States before stripping.

Good news, the piston is the correct height & will need no adjustment.

I will full you in as I work my way through this mod, over the next few days.

Good work Kev, I am sure glad you are attempting this rather than me. I hope you get a good torque gain as you want because this looks like a mod to far for me and most others I would of thought.

You're right there Tony, that is some serious mod you are undertaking there Kev, but if anyone can do it, you can.
