Thanks for the replies. No I have not ran it. I am going to today ( with the stock head). It has new seal kit hot rods crank from Jeff and prolites as mentioned above. I know everything is tight. I will talk to Jeff today and also recheck after my ride today. i also have another tester, it is one of those auto store models that has the adapter that threads on the end. Those are junk because it adds a few ccs because the valve is not in the end of the adapter. Therefore it read about 110 on the stock head. This is why I bought the craftsman tester. The domes do have 20 engraved into the sides.

Anyone have any suggestions. Just popped a piston skirt on a new shee I just bought used. Put in wiseco pro lites stock bore, hot rods 350 crank from Jeff. Went with noss head and 20cc domes. Compression test shows 125psi on stock head but 175psi on 20cc domes. Jeff and NOSS both think this is too high with 20cc domes. Waiting to hear from Jeff on Monday. Squish clearance is .052 and .053 elevation is 985ft. Test with brand new craftsman tester. Dont want to run race fuel. Did find tetraethyl lead to add to fuel to increace octane to 101 from 93. Any input is appreciated.

Running Dominator here from back when it was called series 2000. 50 to 1 for over 3 years, no top end rebuilds needed on any of my bikes and not a single fouled plug in 3 years!! Must be doing something right. Never tried ATF though.

Make sure the hose going from carb to carb is there. I had the exact same problem as you and that hose had fallen off.
