Question on Gas leak - Italjet Scooter

[mattyv]

So I wam looking to pick up a cheap scooter for me and my lady to cruise around into the city on...one where i won't worry about it getting backed into or where i put it...My r6 is my baby...it's not my cheap transportation :-)

So i found this great Italjet scooter - has a PIaggio engine. The bike is 2001 with low miles but has a gas leak. So i went tonight to look at the bike. Starts right up...the girl selling it points out the leak...It seems to be coming from a drain tube..kinda like the r6 has coming out of the engine. THe gas wasn't dripping out, it was squirting out (in a pulsed squirt, almost like a broken blook vessel squirts when the heart pumps). So i am not sure what this tube is for but my instincts said

1) gas coming from a hose
2) hose comes from engine
3) hose is probably a drain
4) gas is coming out, it could be a bad cylinder seal?

What do you guys think??? There is so little info on the bike it's hard to find any real answers.

Its a 125CC 4 stroke motor...

Bump- for needing an answer pretty soon.

you'll need to trace it

even the hoses for the R6 are just vent and over flow, they dont connect to the motor at all
