Why does she stall?


Before I can determine if the lights and electrical are working correctly I need the bike to be running. Today is the second time I have ever run it and both times it has stalled as if it lost fuel or something. I need to determine what the problem is soon so I can complete the bike. I did have the choke on in this video and had held the throttle a hair back to keep it from stalling, which only bought me some time.

Suggestions?

Possible reasons:

"Sounds like it's a fuel starving issue. Make sure that the fuel line is down and under to the carb. I had a similar problem once because my fule line was going strait into the carb w/out a j-bend going under then into the carb. Also check to make sure the air hole in the gas cap is not clogged and that the gas tank filter is not clogged. May also be your carb jets are clogged." -Scott

"Air leak. Explains the high rev as well. Carb basket base gaskets and crank seals are the places to look. Start it again and spray some carb cleaner at the base of the carb (inside the air cleaner), then at the bottom of the basket and if the idle drops at all, then you have an air leak there." - Derek

5/27/2009 Update

It is possible that my fuel line is too long. The correct length (stock) is 25 inches and the fuel line is clear on stock bikes. The other to make sure is that there is a "J" bend in the line going up to the carb. It should not feed straight to the carb.

I will measure the length of my fuel line. I suspect that it is too long for the gravity feed fuel system to work properly, hence the stalls from fuel starvation.

I also need to confirm the correct diameter of the fuel line. The black one I am currently using is 5/16". I was under the impression that black was the stock color, but clearly clear would be easier to use since you can determine that the fuel is actually flowing correctly.



Other possibilities to trouble shoot:
1) Air leak. Explains the high rev as well. Carb basket base gaskets and crank seals are the places to look. Start it again and spray some carb cleaner at the base of the carb (inside the air cleaner), then at the bottom of the basket and if the idle drops at all, then you have an air leak there. -- Derek G.

2) You said you have the choke on? I only use choke for the very initial start up, then I turn it off right away and use the throttle to warm up a bike.

The length of your fuel line from the tank to the carb is very important. I usually measure the length like this:

Lift the gas tank out of the bike. The fuel tap should not be allowed to come above the plane of the frame. The fuel line should pull tight not allowing the tap to come up above the frame. Basically you want the fuel line to be as short as possible without making it too hard to reach the bottom of the fuel tap.

I've had this same symptom when my fuel line was too long. This is a gravity feed system. You don't want to have the fuel travel too far "up hill". -- Michael C.

3) Make sure "clear" tubing you use is fuel-compatible. If you're not interested in a 100-point restoration you may want to use the transparent fuel tubing available via mail-order from Aircraft Spruce and Specialty. We've been using it on our race bikes and it works great. Let me know if you want specific part #s. -- Dave S.

4) As everyone said before, the gas line needs to be the correct length. Clear fuel line is not a problem, as long as you get fuel line, and not some other type of clear tubing. First Kick has the stuff you need.

As for the clogged breather hole, it is unlikely that is your problem. However, it is easy enough to check. Simply try to run the scooter with the gas cap open. If it still dies, then the breather hols is not the source of your woes. -- Paul S.

5) Here’s a quick way to check if your fuel line is too long:

Get a second person to help. Have that person lift the gas tank up as high as it will go. Now you kick over the bike. If the bike keeps idling while the gas tank is held up that high, then your fuel line may be too long.

What you are doing here is increasing the potential energy of the system buy making the petcock that much higher than the carb. Increasing the potential energy will help the fuel flow. -- Michael C.

6) Make sure to have a "J" bend in the fuel line going to the carb. The line should not go directly to the carb. -- Scott

JB Weld seat frame nut

The nut, which is welded inside the frame to lock the seat to was free when I received the bike. In hindsight having is welded into place before paint would have been preferred. After paint I had two options and of course welding was not one of them. I could buy a lock washer and a new nut or salvage one more piece of the soul of this scoot using JB Weld to lock the nut into place.
As you can see it worked just fine. I let the glue cure for 24 hours and tested the screw in it and it was just fine.

The secret to a beautiful and easy reassembly is in the prep work before paint. Dry fit your bike. Screw (not rivet) and shape your floor rails on to the bike. Every piece you can fit it to the bike. I bought this bike and my TV175 in pieces so I did not know exactly what was not in place, such as this nut when I started off. More prep work was necessary and more research as well.

Lesson learned: juts buy a new nut, split washer, and screw for this. The JB Weld broke.

Glove box door on frame

Today I installed the glove box to the frame. I used stainless 4mm hardware. I did not take the time to find out what stock hardware size would be. I also used lock washers and washers with this. With I Dremel I removed the hardware stamp on the visible screws.
Note: this picture needs to be rotated. The fender is on the bottom of the picture and the frame is on the top. The reason for this is because, I didn't look at that parts manual to see that I needed double the amount of nuts. You need two nuts per screw. The angle of the screw is not flush. The first nut locks the screw flush with the frame and the second screw (which I believe is similar to a lock nut) locks the glove box to the frame. I worried about the clearance of the fender to this screw, but after looking it over quite a bit I believe I should be good.

I need to buy four new nuts and washers and then redo this job. Should be easier without the screws spinning.

Não podia ter corrido melhor, se o São Pedro não tivesse a hibernar e a festa continuava na praia durante o dia todo. Mas lá iremos. Muitos amigos do gang marcaram presença, caras novas, sempre bem-vindas. Houve jantar de aniversário da Elsa Garcia e depois bailarico até as 6 da matina. Os selecters trouxeram o seu groove e não deixaram ninguém parado. Na mesma praia, havia festa estudantil com a confusão que isso acarreta, muito transito no acesso a praia. Mas mesmo assim, ainda houve resistentes que conseguiram passar no meio da confusão de carros e poeira. Mais fotos desta festa, podem e devem aceder ao blog da Isabel Tomás, Style Wars aqui.

Awaydays, o filme Casual

awaydays

Na linha de This is England, o filme que estreou recentemente entre nós e que já alguns meses tinhamos recomendado. Surge agora este Awaydays. Baseado no livro de Kevin Sampson, que retratava fielmente a cena Casual, que surgiu no final dos anos 80 em Inglaterra. Neste novissimo Awaydays, um grupo de amigos reune-se á volta de futebol, roupa desportiva, música, copos e alguma porrada com grupos rivais. Enfim, estavamos nos anos 80, Margaret Tatcher governava com a sua mão de ferro e os jovens tinham-se de entreter com alguma coisa. Vivia-se muito na rua e nela havia códigos próprios que surgiam diariamente entre os jovens ingleses. O punk ardeu rápido, o mod revival já era e o Casual nascia nesse preciso momento, inspirado nas viagens dos apoiantes/supporters ás competições europeus de futebol das equipas inglesas que traziam para as ilhas o último grito das marcas desportivas italianas e do norte da europa. A banda sonora está repleta de bandas conhecidas...
Esperamos notícias sobre a estreia deste filme no nosso pais, em data ainda desconhecida. Este Awadays estreia no Reino Unido no próximo dia 22 de Maio.

Eis o cartaz do filme:

Glove Box Door Seal Install

If I were to do this all over again I would:
1) Put the glove box door to the side.
2) Apply Super WeatherStrip to both the metal glove box door and the strip -- running my finger along it to make it smooth.
3) Let them both dry.
4) Cut several pieces of painters tape and put aside.
5) Apply a new coat of WeatherStrip to only the rubber gasket. Avoid using too much. This stuff goes a long long way.
6) Carefully and quickly put the gasket on the glove box frame.
7) Tape it down with fierce pressure.
8) Put the glove box door on.
9) Close and lock the door so as to ensure the gasket has pressure on it and that the gasket fits properly.
10) Peel the tape back and quickly wipe up any excess. This stuff will eat your paint. You need to clean it up immediately and while it is still wet and wipes up like rubber cement. If it even thinks about drying you are too late.

My advice is, prep and practice a dry run so you do not have any excess to wipe up and use a black Super Weathership to match the gasket. It's tricky business because if you skimp on the sealant it will not hold your gasket in place. But if you use too much you will make a terrible mess that can't be 100% cleaned up.
I am not happy with the outcome of mine. My error was in the lack of prep. It could have been a cleaner job. I had to go back a second time and reapply sealant to a couple spots.

I usually use 3m Super WeatherStrip and I have a bias for that brand.

Note: I suspect that the absolute best way to do this is to purchase Super Weatherstrip Tape (made by 3M). It's double stick tape. Tape it to the gasket and cut the excess off. It will provide a cleaner and more consistent seal. This tape cost a lot more than the actual glue I used, but my glue job is just okay. The tape job would be perfect! There is also a 3m spray mount style adhesive that may also work extremely well. My mentor, Tom G., uses contact cement.
