Was it done on a cold engine with the throttle wide open?  Five or six kicks?  That is how a compression test should be done.  It might be a little weak but the rings haven't seated yet.  I would think 120psi would be more normal.

Yes Lyn that's right

Does opening up the intakes to accomodate the Vforce has a impact with compression drop ?

Did a leak down test, no issues found

Did a fresh top end with cast Pistons , Vforce intake work and dg pipes for RD350

Measured the compression - shows 110 PSI on both Cylinders  before a cold start.

Is that a acceptable number for compression or something is missing?
