Four-stroke engine cylinder head porting also improves the volumetric efficiency of the engine be it naturally aspirated or boosted. Your 4 stroke cylinder can be ported, serviced and flow tested for maximum performance gains. Both Titanium and Steel replacement valves are available, seat cutting services are also offered by F1moto at our Dyno tune center in Appin NSW.

All our specialist services are fully supported by testing; we have a flow bench for testing cylinder heads after porting and a Dynojet 250i full motorbike dyno with Winpep8 software for the most advanced dyno tuning in the Sydney area.
