Hi currently have a sigma engine RIOT but am considering changing to R1 power. Does anyone have a list of parts or source of whats needed for the changeover. Also if anyone is interested in the bits coming out, its got a 5000 mile sigma engine, rebuilt gearbox with atb diff, driveshafts etc.
Thanks

Jeremy

Hi anyone got any car to bike engine bits for a riot including engine.
Thanks

cant help you directly except to say that I bought a sigma engined Riot (minus engine) and started my 6 month project of fitting a busa turbo longitudinally. 5 years later the project is slightly behind target completion date...
