i just got this scoot for $300 and am looking for some big bore kits(preferably 2 ring design) in the usa and was wondering what is the engine called since looking up the bike on scooterpartshop only came up with a 62cc single ring kit with no head
ive also read somewhere that one of the ways they limit the speed of the bike is by under sizing the belt so what belt should i run since the bike likes to grab pretty hard off the line so idk if its the right belt for it
been beating my head on the wall tryin to find a 62cc bore kit please recommend thanks!

Morini type engine, not much for cylinders with that brand, Well made though!

I had one of those and it was a quick little scoot. Here is my build thread on it: 49ccscoot.proboards.com/thread/14870/hyosung-2002-prima-craigs-list

Parts are available but hard to find. Scooter Tuning, ScooterPartsco and RacingPlanet USA. Most anything for a Morini engine will work.

thanks for the info guys ive solved all the issues ive found on it but gonna have to get a new ignition for it since it will not turn off when i take the key out might try and fix the original but no idea how thats gonna go

can anyone tell me how i can get the rev limiter i think from screaming at me when i push it
or could this be my injection pump? i had to switch to pre mixing since i could not tell if it was working after i pushed it to 40mph it was cold out so idk if it was even getting oil

[clutchmaster]

also was wondering if this kit will work on it

That kit "should" work. Hyosung made a lot of their parts one-off ,like the gearbox and ignition parts..
