Hello all new to the forum here. I have 90’s a manco streaker with the 3.5 Tecumseh engine I used to ride as a kid. Just got a place with a garage so Was looking for a project. The bike is not with me at this time and the engine is sitting on the shelf at harbor freight. My question is will a predator 212 engine fit in the frame of the manco streaker 580. I know before I put the bike away say 15 years ago the engine was tired and needed a carb. Figured for 100 bux I could put the predator on it and ride around the yard and on some trails. Was wondering if any of you Saw this build before or know if its possible without extending the frame Thanks for the help!!
