Got a "new to me" bike and I need to rebuild it.

TheBeard84 · 04-04-2022, 10:45 PM

I just purchased a clapped out Chinese dirt bike, The jug says it's 72 ml which would be a 72 CC. Under the left side of the engine it says 147FMD. This beast has next to no compression, it was "well loved" AKA used and abused. I'm looking to do a Big bore kit on it and I just want to make sure I purchase the right kit

. Also, how big of a bore can I go with this engine style? Any help would be appreciated.
