Hello fellow valksters, I have an 01 std desmoged valk. A few months ago I was riding and about 65 - 70 miles into the ride it started losing power like the fuel was low, which was confusing because I just topped it off before the ride. So switched it to reserve and power kicked back in and I headed to the gas station, filled it back up. It didn't take more than 2 gallons. Started back on my ride and it happened again about 65 - 70 miles into the ride, filled it back up and headed to the house. I was thinking it had trash in the tank so I cleaned the tank over a few days, put it back on and the started her up. The problem was worse, popping and wouldn't stay crunk. I took the tank of and cleaned it again within the next couple of weeks and it wouldn't start at all. I noticed that fuel wasn't flowing into the glass inline filter from the petcock. Eventually, I checked the petcock, it was faulty and replaced it with an OEM petcock and cleaned the tank again for good measure. I put the tank back on and it still wouldn't start  . I searched the site for some directions on what could be the problem. I checked for kinks in tubes. Does anyone have any ideas on what could be the problem or what to check or something? |

Not speaking from experience here but from what I've read on several occasions, get rid of the aftermarket inline filter! I guess our fat ladies aren't fond of 'em.
And welcome aboard!

As was said nix the in-line filter and jump it to your car. You may have run the battery down. It doesn’t take much and even if it turns over it can still be the battery. Also if you have an extra key try starting it with the gas cap open. If that helps you probably linked the vent line at the tail of the tank

FWIW(probably not much), I've been running an inline filter for at least 10 yrs. or more with no trouble. The key is all the fuel lines MUST be running downhill with no low spots. I have a Pingle petcock, inline filter, and a DanMarc elec. shutoff, all leading down to the Tee where the fuel lines split to feed each side of the carbs. No starvation experienced, this past Sunday while cruising some country roads I made a couple rather "spirited" runs...the spirit was quite willing and capable.  |

The in-line filter was on it when I first got it 2 years ago and I replaced it with a clear one with no problems, it all runs downhill but I will see if removing it works.
I tried starting it with the gas cap open several times and checked the vent line for kinks.
I have the battery on a tender to keep it charged and tried to jump it with a charger that I use to jump my trucks with
Thanks all

Try the "vented" fuel cap option (just open the fuel tank and try to start it. If it runs fine that means the inner vent line inside the gas tank is full of junk and is causing this starvation syndrome.

Your carb fuel bowls are most likely empty. The petcock is vacuum operated and The engine may not provide enough vacuum to open and let the fuel down. Remove the vacuum line off number 6 intake runner and put a little vacuum on that little hose for at least a minute with the fuel valve in the ON position. Reconnect the vacuum line and try to start the bike

I have witnessed this happening on several Valks over the years. Loss of power after 30 to 60 miles of steady running on full tank. It will keep getting worse until you can only ride a few miles at a time. Replacing the cover set has cured everyone of them. Do like F6Lady rider suggested and check the petcock with vacuum.

To help me understand if I run into this, or even if I want to try to 'head it off', what do you mean by "the cover set"? |

Most all the problems causing this, have been mentioned already. If this happens in the future, you can bypass the clogged or kinked vent line problem by sticking a coin under the gas cap to break the seal. I had fuel starving problems on the long haul to WV Inzane while pulling a Timeout camper. It was during hot weather and fuel mileage was bad - down to 17mpg. It was worse climbing long hills on the hot afternoons. Found there wasn't enough head pressure to feed the engine through the smaller Dan-Marc when the tank got below half, when it was really hot. Workaround was keep the tank fuller and slow down. That meant transfer the fuel from the belly tank sooner. I have a custom belly tank install that preserves the OEM gravity feed. I fixed the causes when I got back to Colorado.

Have you checked the vacuum line for leaks. Might not be getting enough vacuum. I know the external filters will work but recommend just the internal filter.

Ok, I tried removing the in-line filter, checked the cover set on the new OEM petcock (it looks good and passed vacuum test), and tried what F6Ladyrider suggested with the vacuum line and still no fuel flow and will not start.

When changing the fuel position on the petcock, you need to feel those indents where the set ball falls into their hole, to indicate that the valve (petcock) is in position to turn on/off fuel.

I feel each indent on the petcock. |

Why not take the tank off, put vacuum on the petcock and see if fuel flow out the bottom of the petcock when you move the selector to ON and RESERVE? If it does, you know the problem is between the tank and the carbs. If it does not, then you know the problem is with the petcock or tank. Seems elementary to me. You may have already done this.

No need to pull the tank, use a short length of vacuum tubing, substitute it on to vacuum line barb on petcock and open a carb drain screw, let it drain then put vacuum on the end of the vacuum line (pump or old fashioned just suck on it) and see if you get fuel out the open drain on the carb. |

Can the OEM pos and replace it with a Pingle. You can not run it out of fuel going wide open. 17 years with no problems. Buy once, cry once.

Make sure that you do not have a fuel line that is separating and the inner wall is collapsing. A separation will not show from the outside, but will slow the flow of fuel.

This is not a conclusive test for a couple reasons. One of the weak points of the OEM petcock is that at its best it flows just enough fuel to just meet the need at higher rpm and as things degrade it flows less and less until you experience fuel starvation. Secondly because its gravity fed, the weight of the fuel is critical as the efficiency of the petcock decreases over time due to diaphragm wear and tear. So even though you may get it to flow fuel using the test you described, its hard to measure volume of flow and as the tank empties the weight of the fuel becomes more critical as the petcock gets worse. Its more complicated than just will it flow gas |
