Good Day Everyone.  I rebuilt my petcock.  Everything went well and done according to instructions from shop talk.  Did the little suction trick before putting the petcock together and the diaphram worked well.   Bike turns over but will not start.  All hoses are connected.  Nothing that I can see is pinched.  Bike is a 2001 IS.  Any advice would help.  Thanks Tomkat.

My guess would be a kinked vent hose when replacing the tank....ask me how I know.

Nope not out of gas.  Battery fully charged.  No problem turning over.  Seems like not getting enough gas.  Vent hose looks OK, will check again.  Tomkat

Well then back track.
Was running. Took it apart and now it just turns over but will not start.
It's not a gas problem. It should start and run for quite a while on what
is in the carbs.
What else did you do?
Unplug any additional wires?
IK would pull the tank and look check all wiring in that area
making sure all plugs  are pushed all the way in.
Also check the red stop switch on the handle bar.
I'm thinking that it does not crank either if that is off.

Did you by mistake put the vacuum hose from #6 on the vent line and the vent line on the petcock.  If so I won't run.

In addition to that I would look for a kinked fuel line.

Hi Tom Not to seem like a smart ass but did you put the petcock back on right? I did mine and had the petcock shaft on 45 degrees out.When I had it on the "on" position,it was actually on "Off" It ran for a very short time and died.

It is possible to reassemble the petcock oncorrectly, it's also possible to connect the vacume line to the vent nipple. Is there enough gas in the carb bowls to start the engine, if not you will have to apply some suction to the vacume line to get gas to run into the bowls before anything will happen.
This last item had me inventing expletives after tank and carb work.  Angry

Open a drain screw on a carb.  See if there is gas.  Disconnect the vac line where it attaches to #6. Then, with the gas valve on, suck on the end of the vac line to the petcock.  Gas should begin flowing out of the open drain screw. If yes, gas not a problem.  If no, then something is wrong in the petcock.

Oh, Dang-that's what I meant earlier...kinked fuel line. I added a quick disconnect, made it just long enough to kink and not flow. Sorry for the "vent line' suggestion earlier.

Whenever mine sets for about 6 hours or more, I pull the choke on and  fire him up.............

Don't be afraid to use the choke, that is what it is there for.

Make sure ya got it ALL THE WAY on.......

When ya hit resistance, push harder, it should move some more.

The choke handle should be pointing directly across the tank to the other end of the handle bar. tickedoff 2funny coolsmiley angel cooldude

The bike WILL die if you leave it on full choke after it starts, just let it up a little bit after it starts, it will fast idle for a couple minutes, then release the choke fully and take off.  I'm old enough to remember manual chokes on cars, works exactly the same.  hoser

Thanks for the response Hoser.  Haven't had a chance to look at it today, but as soon as i take the choke off it kills.  I need to remove the tank and take another look to make sure everything is connected right and nothing is pinched.    Tomkat

I remember about 10 years ago a guy filled up with Diesel by mistake, would only run when the choke was on all the way, not good but did run enough to get to town. 2funny Took it to Honda shop in town and after a few hours trying to figure it out they finally smelled something funny. Emptied the tank and who would have thought it started right up. I know what you are thinking but this did happen and with about 30+ Valk riders around no one else had a clue what was wrong. Just  a thought.

No problem turning over.

Not that this is your problem, its just the "no problem turning over" thing gets a lot of Valk owners.  The first classic sign of a weak battery on a Valkyrie is when it turns over strong but does not fire.  Just to remind you and anyone else.......if the battery was borderline and it sat for a few days, it may not have the power to run the ignition even though its strong enough to turn over the motor easily.......just sayin......

To take all doubt out on a battery that is getting ready to poop, take a car battery, or pickup battery, MAKE SURE THE JUMPER UNIT is no RUNNING.

Hook up the bike battery & hit the starter.

If it starts, go get a new battery.

If it don't start, then start digging into why not.

Bike battery may have enough juice to spin the engine, but not enough juice to fire the coils and let it start.

Sometimes when you are letting off the starter they will start, same deal, go get a new battery.

Good Luck, cause I hate to chase these no starts also.

1st thing to check is the last thing ya screwed with in the electrical line.   Moving handlebars falls in this area also.
