20141207_144114.jpg Being I ditched the gasket so I didn't haft to cut the base so thin. I use motoseal to seal them back on and let them set over night and then I reign the cylinder
 
20141207_144048.jpg 20141207_144056.jpg I use the gasket to match my exhaust port and then I use it to transfer the pattern to the heat shield and exhaust inlet.
 
And here most of my final numbers. Intake is 76°, exhaust is 102°, trans are 112°. I took .043" off of squish band and .015" off of base with final squish being .024". Hopefully I can finish it up tomorrow and get you a compression number.
 
20141207_190852.jpg Another spot I had to clearence. I ground out the lower bolt holes in the muffler up just a bit. The bolts probably would have went but they were tighter than I wanted.
 
20141207_194409.jpg Ok boys she's back together. Now this pic is showing the compression but I will get you an accurate one once I run it. When I put them back together I coat the cylinder and piston with 2 stroke oil. And put a couple drops on the bearings. So usually they read just a tad high. I would say it's gonna end up around 190ish. But we'll see.
