* "Pagsta" is not a recognized brand: There's no official motorcycle manufacturer called "Pagsta." This suggests it might be a custom build, a generic brand, or a misspelling of a real brand.
* 49cc is a very common displacement: Many mini bikes and scooters use 49cc engines, and they can be sourced from various manufacturers.
* "Mini Harley" is a descriptor: While it suggests a Harley-Davidson style, many mini bikes and scooters adopt a similar aesthetic without using actual Harley-Davidson parts.
To find out the specific engine type, you'll need more information:
1. Verify the brand: Is it truly "Pagsta," or is there a different spelling or manufacturer?
2. Check the model: What is the specific model name of the mini Harley?
3. Look for markings: On the engine itself, there should be markings indicating the manufacturer and model number.
Once you have this information, you can search online for engine specifications or contact the manufacturer directly.
