1150cc HRSR Imp Racer

75mm liners prior to final assembly

5/8" spacer plate adds rigidity and eliminates liner shuffle

Dummy liner, for checking concentricity

Down draft head

Head machined to take 1.38 inlet and 1.210 exhaust valves

Final operation was to skim the head at an angle to create a 'wedge head'

Wills ring groves also re-machined

Future Project Ideas

Metro sub frame purchased, still a long way to go!
