hey,
having some trouble with the fuel swith on my cb...tank is full but no fuel is flowing through the line...how does one go about fixing this? do i drain the tank and then remove and clean the fuel switch? is this a common occurence...
any help would be greatly appreciated! thanks in advance

you will need to drain the tank and remove the fuel petcock. it MIGHT be able to be cleaned BUT a rebuild kit is usually less than 25 bucks and gives you all new seals. if it was my bike i'd rebuild, also if getting clogged is a regular occurence you might want to think about coating the inside of the fuel tank too. theres lots of different chemicals and systems out there but i've found the por15 to be the best by far. if you do use it FOLLOW DIRECTIONS CAREFULLY.

some people are like slinkies, basically useless but they still make me smile when i push them down the stairs

pull the petcock bowl and screen, if you get fuel dumping out its the lines, if not you know things are clogged up on the inside. Drain the tank somehow and pull the petcock. A bit of carb cleaner and some compressed air should do the trick. Make sure all passeges are clean and all rubber seals intact. If the tank is rusted/ shitty TRY to clean the crap out then either Evaporust or acid-etch it. I (personally) wouldn't line a tank unless it showed holes. If done improperly the lining will flake off into your fuel, effectively ruining the tank.

Another thing to consider:
IF the tank has debris in it your carbs will.


Acid etching process how-to:

(In line filters help too)

hey, thanks a lot for the info. it looks like the carbs are getting fuel...i pulled the fuel line out of the carbs and gas drains out...so looks like there might be something blocking the fuel getting in the carbs? do you guys recommend carb cleaner i guess?
it was running like a top but sat for about 2 weeks while i was out of town...BUMMER!

 

[texmawby]

yep, carb cleaner is your friend.

good luck.

If it sat for two weeks you probably have some buildup in the carb. Always drain the bowls before letting it sit for any period of time. WAY easier than cleaning 'em every time! Clean them carbs AND check your gascap vent! If the vent is blocked it creates a vacuum and cannot flow.

Evaporust works wonders...I pretty much dipped my entire bike in it part by part, including the inside of the tank. Nice thing to is that it is environmentally friendly so it is easy to dispose once used up... I prefer just to drink the stuff, because it usually taste better then the cheapo beer I have in my frig... I suppose I could just buy better beer.

Note to Sotoman. I was kidding about drinking the stuff...Don't drink it brother.

petcock bowl and screen, again. do it.

Sounds like you just need to prime your fuel lines. Did you recently change the lines/filters or drain the lines for any reason? If you're running the stock petcock, an air bubble in the line can impede/restrict flow.

1. Remove both fuel lines (with the petcock off)

2. Hold the "rear" line just under the rear petcock nipple and turn the petcock to reserve. Allow fuel to drip into the line (and the trapped air to escape) until it just starts to spill over then slide the line on the nipple. Don't worry, fuel won't leak out of the front nipple until the back line is primed. So, once the back line is primed, turn the petcock lever to "off."

3. Repeat for the front line.

I just drilled a tiny hole in my gas cap to vent it. Not pretty but it works.
