Anyone try the china girl GT80

[joetrammel]

I'm a bit curious if anyone has tried this engine yet Heres a link http://www.gasbike.net/collections/...acing-engine-66cc-4-5-hp-with-ported-cylinder

I've never dealt with specialty ported cylinders nor reed-valves, but doesn't the piston need skirt-porting as well to take advantage of this configuration?

I have one, still breaking it in but she runs smooth and has good power. Was ported and overall clean for a China.
