C90 ignition ? timing
as the timing is a fixed pick up point ..
What is the best ignition advance for these engines please
the motor is running a long dwell cam with slightly higher lift.
C70 high comp piston and
ct 70 big valves in the head with 24 mm inlet carburetor
my thinking is about 25-38 degrees btdc
Also is the oil take off plate that sits on the head able to be used to feed a remote oil tank?
any thoughts and prior knowledge of this or similar set up information wold help with initial set up.. regards in advance

Good idea, But Have you increased the oil pump.

how does one increase the oil pump flow?

With the honda GBG OIL PUMP, Part numbers 15100-GBG-931 you will have to drill the oil hole out next to the bottom stud,
Depending what cases your using you will have to increase the galleries behind the pump.
12v c90 cases you dont, But c50/c70 im sure you do.

there is a guide in the how to section on these pages.
