the engine i have had been fitted in a quad and the tacho drive had been removed including the shaft in the engine so i will need to reinstate these
where is the best place to go for such parts and gaskits

Hi mate engine fit's straight in you will need the full 31K loom and electric's you can mount the servo motor under the coil where you plug in the 4L1 switchgear and if my memory serve's me right you need to change the spacer behind the front sprocket from 31K to 4L1/4Lo so the chain run's true im sure that is right but it has been over 20 year's since i done this conversion
