I got home and replaced the condenser last night. I tested the compression at 215 PSI, so I swapped a different head on and it's now 175 PSI. Then went on a 15 mile night ride. I had no major issues! The silencer fell off of the circuit pipe but that was an easy fix.
It runs great, no 4 stroking, I could probably lean the jet out a size or two judging by the plug. 33 MPH is the fastest it'll go with the stock 18x40 gearing. The speed/rpm calculator show its turning right around 7,000 RPM. Still waiting on 20x37 gearing to come in the mail.
What is the typical RPM for a circuit pipe? I will need to be closer to 9,000 RPM for a solid 45-50 MPH bike. The kit is spaced/clearanced correctly. Using a 15 bing with no filter. Im thinking the intake might be holding it back some. I have two aftermarket ZA50 intakes on hand. They are both round port intakes which I assume is to match up with the stock ZA50 high torque cylinders. I think I have something coming for a square port ZA50 intake and hopefully that'll give me more RPM.
