As above. Head is a standard injection type which is unmodified, vernier pulley, 205 block bored to 93mm. All balanced bottom end.
Sanspeed tuned by Peter Sansom, only recommendation was to use harder "7" grade spark plugs.
Was a good hour £100 well spent IMHO, first run was 125bhp approx, when Peter had finished it was close to 150bhp with better manners and above all this safe. The engine was dangerously advanced.
Could help but laugh watching someone else cane the living daylights out of the motor
HTH
