Compression ratio
Yep, another CR question
1916 with a 22/62 (AP3??) cam
Head volume to 50cc
Dont know the deck height as I havent pulled the old ones yet
Guessing it would be 60 though (1.5mm)???
Heads have a 1.5mm "step" for decompression from the states
Wondering if this should be machinjed off??
The 50cc is to the top of the step
Is over 9:1 ok for a daily with Sydney fuels??
I normally run 95 but dont care if I have to go to 98
With a 1.5mm deck the above come out at 8.9:1
With a 1.0mm deck it is 9.4:1
I havent allowed for any shaping of the chambers yet
Futue te ipsum!!!
