what does the HP on item for sale mean and do the 49cc engines come with the reed valve system?

HP = High Performance

The typical 49cc found in the midbikes is actually a 43cc piston port motor. The 47cc found in the small pocketbikes is actually a 40.2cc case reed motor. Some of these also come with a +4mm larger bore making them 48.7cc. But, some of the smaller pocketbikes also come with the 43/49cc piston port engine.

On the reed engine the carb goes into the cases and on the piston port engine the carb goes into the cylinder.

so if my mini is a 49cc reed how do you know what to order for parts cause they dont tell you reed or port in the adds?
