OK, did a little more testing. Still cant recreate the leak.

I tried to both blow air and suck air through the fuel cap - which is quite easely possible.





Also disconnected the vent hose from engine and tried to blow air and suck air through it. Also with a compressor
That was not possible - not shure if it should be.



So now I really need to find out for shure, where the leak is coming from. So I have placed dry Toiletpapir on the tank and will take a look next time I smell gasoline, and also note other things like how full is the tank. How warm. How long ride and so on.



Hello, It looks like you've added three photos to this post. They are not opening for me.
Also, there is a rubber seal under the fastener for the fuel-level sending unit.
A leak could be there if the spin-on fastener is loose, or rubber gasket under it is failing.

The vacuum line from the top of the fuel pump is attached to the emissions canister. The canister stores fuel vapors from the tank when engine is not running. Engine on - the vapors are carried to the bottom of the throttle body and then burned in the engine. There is a one-way valve in that octopus of vent lines! No fuel should be reaching up into that top line....unless you and passenger are in a moto-X !

The fuel tank cap has a hole for venting are in to prevent fuel starvation and lean running.

Most of us do not fill above that 'bar' seen down the filler neck in the tank.

Maybe differnt years or one of us has an unoriginal.

Here the model looks like mine.

And I can blow air in and out of the little hole, so should not be create a problem unless tank is over filled.

Nice Stig! I'm just starting my look for a fuel pump, thanks for posting this. Looks easy enough to do and the high flow will be nice.

Thanks!

Hey guys, sorry for the delay in getting this done but I have news and another question.
I ordered a new Non OE fuel injector, put it in and it runs again. Took it for a ride and it did great. Back to normal performance. The one thing is doing now is wanting stall out when coming to a stop. It's always been a little like that since I've had it with only 370 miles on the OD. Now it seems a little worst. It's a little punchy at slow speeds, around 10mph, and that's always been there. As for the stalling out, any ideas?

Happy and safe scootering, Ruffus

If the TPS re-set doesn't fix your stalling at idle.....  I'd try an Iridium spark plug.

The NGK CR7HIX "strengthened" my idle by a few RPM's
I also tried the DENSO IUF22 Iridium - but I liked the effect I got from the NGK better.

Sitting at a light - surrounded by a dozen cars in a 12 lane intersection - the last thing I want to hear is my idle dying away!

*note on the NGK - once firmly seated by your fingers - NGK recommends 1/2 turn more with wrench, only!

Update. I have another post about this but it's the wrong thread I think. I'm going to have to clean the new injector and am in the process of removing the fuel tank for cleaning. There's varnish in the bottom. I'll also install an in-line fuel filter before the injector.  I'm having trouble removing the engine cowling. There are screws or something at the base holding it but I can't find it. It looks like it's holding at the rear base of the cowling and at the front sides connecting to the floor. Anyone have pics of removing the cowling? I'll take pics to post here.

Hello - I don't think any panels have to be removed in order to remove the fuel tank. Maybe removing the center panel will make things easier? This panel is easy enough to remove.
Remove the seat and the under-seat bucket.
Cyclepedia.com manual has pretty clear photos involving the removal procedure of the fuel tank.
If you plan to keep your LIKE200i for a length of time - might be a good investment. It has been for me these past 13 yrs.

I unfastened the center cowling, I felt I needed to do the to get to a couple of bolts holding the tank in at the rear. It's now out and soaking. Thankfully there's only a little varnish and no rust. I'll put it back together tomorrow and test it out. The filter attached to the pump has a couple parts covered in varnish but I'm sure that'll clean off. Having an in-line filter should help a bit as well. She's a little old but still looks pretty good. I'll take a picture and post it once she's back together.
