I've just fitted a BGM cylinder (0.7mm shorter than standard 200 barrel) and Pinasco cylinder head to my 60mm 200 engine with a 0.5 base and no head gasket. The squish is a fraction under 2.0mm. Will that squish be ok as standard engine can have about 2.5mm. The compression has definately increased. The bowl in the head seems to be smaller than standard, could that account for it and could the engine now have too much compression?
