Hi there fellow Chappy lovers.
I have a 3-speed semi automatic 50cc Yamaha Chappy from 1979.
And as i browsed though https://www.treatland.tv I saw the following MLM exhausts:
There is a couple of variations of the Chappy model so I wonder if anyone had this mounted on a model with a similar design as mine (see attachment).
The path of the exhaust is quite narrow.
I would also love to see photos of your Chappys with ant of the MLM exhaust mounted.
