Really Thanks.

With an unknown cam - which this is - to me and you - the rules for setting up are simple:

1. Cam Lift(mm) mm Inlet/Exhaust - Measure it with a dial gauge

2. Valve Lift(mm)mm Inlet/Exhaust - Set up the clearances and measure it with a dial gauge

3. Duration Deg Inlet/Exhaust - You really don't need to know this. I rarely use it.

4. Timing & full lift - you can set them up with anything to 100 - 110 degrees.

6. VC - set ex at 0.018" and inlet at 0.016" cold with tolerance of +/- 0.002"

8. Power band RPM - you will find out.

You will have to get yourself organised with protactor and dial gauge etc and read my 'How To' below.
