Took the Valk up to Daytona from Orlando today to get a new helmet. Ran smooth as silk as it usually does. Put her in the garage for about an hour and a half. Decided to go up to get some eats, got about 2 miles down the road and she starts chugging like the main tank was out of fuel. Come up to a red light and she quits. There were 4 bars on the gauge and the gauge has so far been accurate. Switch to reserve just to see what happens and she will not start. Pulled over up a ramp to the sidewalk, checked connections, opened the tank and heard some fuel sloshing, closed the lid, tried to start and just kept cranking, no pop. Checked all the connections again just to be sure, no kinked lines or disconnected lines. Tried to start about 3 minutes later and she fired right up. Switched back to the main tank and she ran fine back to the house. Getting nervous as I'm about ready to take her up to Chicago and back next week. Bought her back in January with 29,400 miles and I've put about 3,000 miles on since then and have not had any issues to date until today.
Any ideas????

Bob, I have a 2000 IS also. If it is running fine it will be difficult to find something wrong. Must have been fuel or ignition. If it was me I would find a way to check battery voltage while you ride again. Multimeter or voltmeter between battery positive and the frame of the bike. Most if not all of the ignition parts, coils etc. ground through the bike metal frame. The battery ground wire attaches somewhere on the engine and not the frame, then a separate ground wire (problem on my bike) grounds the engine to the frame. My bike the battery voltage was good but when I checked through the frame I did not have 12 volts. The ignition system needs close to 12 volts to work. Mine would miss and die at low rpms. If it dies completely you need to be ready to check for spark. Other spark related possibilities I can think of is side stand switch, main fuse holder likes to melt, possible kill switch or pulse generator but usually not.
Fuel could be a vent problem,(open the cap) Stopped filter screen above petcock, or bad petcock, they are vacuum operated.
Ignition usually feels like very quick and strong misses, fuel is usually slow to come on and slowly gets worse (running out of fuel). Need to ride and figure fuel or ignition first. Let us know so we can help. Firefighter

Sounds like a clogged or pinched/kinked tank vent hose. Had the tank off lately?
Anyway, I'd start there.

Mine acted like that when the petcock started to go bad. If its the fuel valve it will get nothing but worse. May run great around town, but once at highway speed the petcock may not flow enough fuel to keep the carburetors full if its starting to go bad.

OK guys, after looking at all the responses and options, I decided to replace the petcock. Due to time restraints I ordered the OEM complete assembly. Picked it up today and just got home. Removed the old petcock, tried to remove the soft plastic screen/fuel strainer and won't budge. Didn't want to screw it up so I need some advice on whether to keep that piece in and just put in the new assembly or do any of you have a way to remove that easily?

Don't toss your old petcock. Get a cover set kit and put in. Then you'll have a spare.  |

Already had that in mind meathead!
Put the tank back on, cranked her up on the lift, ran about 15 min at 2500 and no leaks and no stall.
Going to bolt the tank back on and take her for a ride up I-4 for a bit.
Thanks for all the input guys! Greatly appreciated! Now I just have to see if the weather will hold out for a Saturday 1st leg run through Ga. Not looking too good right now.

I would still be curious as to how old your battery is....the bike is 12 to 18 years old and battery's last maybe 5-7 years......generally..

When the filter screen is hard to get out I sometimes use a 1/2 tap and tread it up inside the tube and I can usually take one out without damage.

I think the only think I damaged was the O Ring. Should be able to salvage everything else. Will order the kit and have a new one ready.
Thanks Attic Rat
