I thought the same thing with regards to the pull start... but all the paint & mounting look original
If it's not original then I'll monster truck it... With this,, I just finished putting a new Carby and tunnig it. This is my spare Yamaha MT110 also have one on my everyday User Greenfield push mower.. Luv the grunt these engines have.

Such is life....... Nothing better than a "GreenField" just mowed..
