Good luck fitting the 2in1. |
When I originally checked my 620 a few months ago I got approximately 3% leakage on each cylinder when pressurised to 60psi
I was told if its below 8% not to worry, above that and you have hissing in either the inlets of exhasut ports then its worth lapping the valves in.
If its hissing through the crankcase breather then consider new rings.
Hopefully fitting the 2 into 1 will be down to good design and craftsmanship and not luck, Its the harness I need the luck for
