I just checked mine.. 105 PSI.. but starts good and runs good! am I losing that much power?
Got my Jug back from the machine shop yesterday. Going to install it today. What are the torque specs on the jug and head?
Also, arrow on piston points toward exhaust, correct?
Thanks,
Leo

Have a Chinese tester and got 105.. used better tester and got 140!
Make sure you do a proper break in! VERY VERY IMPORTANT
do your heat cycles.. run 20-1 mix, USE GOOD 2 STROKE OIL
Got some time to do the re-assembly. Roller Bearing I bought was the wrong size, mine was a bit larger. Anyways, mine was in good condition so I re-used it. Used Assembly Lube on the bearing, piston rings and shaft and cylinder walls. Got it all together and did a quick compression test and 170, now that's a whole lot better. Should get better once the rings get seating in.
I also replaced the 150 main jet and put a 155.
She fired up on the 2nd kick. I also took a quick video, smoke is burning off all the lube. Took a quick spin around my yard and adjusted the a/f to 2-1/2 turns from close. I can already feel the new power I got from that overbore. Can't wait to get it out to the Desert and open it up.
