Aprilia rx50 2004 dies after 5 minutes

[paddee]

may have the problem solved ??
Again he came back in about 5 to 10 minutes, bike dead again.
Petrol in float bowl was almost oil like!
The breather tube on idle screw side was connected to a nipple on to of gear box.
When we got bike, there was a tube in same place, but was just a bit too short. So I replaced with longer tube and connected them up.
Thinking crap from here is feeding up the breather tube, back into the bowl, blocking jets, cutting out bike.
He's back out on bike, with no tubes connected for now.
Feed back on this thought please

Well?

How did he get on?????

[paddee]

not too bad.
The air filter got soaked, as it's just one of those foam things (don't like em me self)
So bike came to a halt.
Air filter off, runs ok. Got a new 'covered' air filter on order.
I'm thinking we're so close to a fix now.

Thanks so far for all the input.
Will update after his next ride out. Probably tomorrow afternoon.

There shouldn't be a hose from the carb to the crankcase /gearbox breather, they should both vent onto the floor basically.......I've never heard of a jetting problem letting it run well for x amount of time then stopping it dead.

When bike cut out. The bowl looked to have 'thin'oil.
All vent pipes replaced with new. All vented to floor. Bike is running much better.

He's been out these evening, after school, and still going ok.
Looks to be good.
But I'll replace fuel pipes any way. Not much else to do with it now.

Well done for getting it sorted.
