Well, the exhaust port was rough, transfer ports on the cylinder side were not straight, piston did not look graphite coated, spark plug was cheap, etc. After some investigation into the matter, I found I had the correct kit.





So begins the process of getting the parts up to specs.

Here's the exhaust port after a lot of hours working it. Notice it's still really rough. I used a dermal with those fiber sanding discs, hand sand with 2000 grit, and finial polish with buffer bit and some fritz polish. There was also a GP stamped into the side of the exhaust port. Does anyone else have this, or can someone confirm that this is normal?



I herd the GP is the person who did the port work on the head? but im not sure if it's true.




I was also disappointed with the finish on the head by the spark plug recess. It was rough and had a sharp edge. Out came the wet/dry sand paper. I'm also going to try and smooth out the CNC ridges from the cylinder head surfaces later. I don't know if it will make a difference, but I figure it would make it harder for the carbon to stick to and lower the compression a hair.
