Here is a complete 2017 Honda Montesa 4rt engine,  Engine is complete minus Kickstarter and shifter.    Also included,  wiring harness throttle body ecu and injector and lines, throttle cable.     If one were to put this in a different bike you would only need a small universal fuel pump that creates the same psi to run this setup.    This was for a project that never came to be.     Then engine runs great, and has great compression, and does not smoke or leak.     solid little engine that ready to go.      The though was if someone in the states was looking for an engine for the bike,   it may not make sense for it to be shipped back over seas, but Im not against it, it your money.    Asking 1030 gbp                  or 1300 US    cheers  -Scott
