Hi all I have a yamaha 1983 YT175K Tri-moto These come with auto clutch and pull start as standard and I have heard that parts from 1983 IT175 are very similar and can be swapped with a little modification. I dont want to start this without a little info on this as i have not worked on many old yamahas before. Is ther any one on here with any knowledge on the IT175 engines or parts for sale that are likely to be needed
