Aprilia Tuono 125cc

[vjezerick]

Hi guys. Hope you're all well.

I have recently bought my aprilia "april" heh and there's has been afew problems along the way.

#1 I heared the starter motor sound(when you press the ignition button) when I pulled up, at the lights.

#2 in third gear(sometimes 2nd) just as I'm about to hit power band the bike cuts out.

solution: i checked the rave valve and there was half of the circle missing, so I replaced it with a new part.

#3 now that I thought I fixed the issue, I attempt to start the bike up and noticed there was petrol firing out into the exhaust and when I took the exhaust off previous to fitting the RAVE VALVE, there was plenty of petrol in the actual exhaust. I'm talking PLENTY. almost all full of petrol.

attempted solution: I removed the carb and check it out, there was a piece of red type hard material in there, not in a position of harm, but, there non- the less. I removed that and re-fitted the carb and went onto decoke the piston head.

that's basically it, i have no idea what's going on. My main concern is the petrol and where it is going.

any speculation would be massivelty appreicated.

take care, Dan.

sorry, i'm not that well educated.

For that line you deserve all the help you need

Have you cleaned the carb, air filter, can you tell us more about the bike age and condition ?

How olds the sparkplug ?

Checked the fuel line is in A 1 conidtion ..

That will do for now

Finding a piece of 'stuff' in the carb explains the petrol.
This part probably jammed the float open.
The float stops fuel coming down to the carb from the tank when the carb is full - so if this is jammed open, fuel will keep flowing down.
As it's a 2 stroke, fuel can flow right through from the inlet to the exhaust. This isn't uncommon.

Note in future that when you've got the carb off it's worth cleaning out the jets. Take each jet of indivdually, inspect it by eye and blow through it hard by placing it between your lips (so it's sealed) and giving a decent puff out.

If petrol is flowing to the exhaust then it may be worth checking your oil to make sure the petrol hasn't seeped past the piston rings and into the crank case. When I had my TDR250 I had a similar issue with fuel in the exhausts, can't remember the cause though, a few years without a stroker and my mind is blank!

I really am confused then, I'll take this opportunity to STFU and stop offering advice

The crank case area is used to pressurise the fuel/air mixture and force it into the combustion chamber.

As it goes I remember my dad explaining something like that when I had my TS50, probably should have listened better!

So wait a minute... Now you've removed the hard red substance from the carb... Is there still fuel coming out of the exhaust? If not, then I suspect you've fixed it. If yes, then there is something else wrong.

Remember kids, bikes aren't like lego. You can't easily take a part from one bike and then fit it to another.

Got a picture of what you removed from the carb?
