Possibly check the vent hose for the gas tank. It here is water or another obstruction in the tube / line could cause a vacuum in the tank which would cause the fuel to slow or stop flowing to the carbs.
On another note, please elaborate on what you mean by "Car Wash" Thanks.

 

Hmmm. Going back in time and doing over is NOT an option, I have tried it. But, dont do that again, same goes for pressure washing.

You need to drain the fuel tank to remove water, drain the carb bowls (drain plug), disconnect all elec connectors and spray with wire dryer then smear with dielectric grease.

Pay attn to the spark plug and ignition coil wires.

I will bet (no $, just bet) that its a fuel thing cuz wet wires generally dry out days later.

I am trying to picture you putting the hawk in the wheel track of the carwash and hoping it gets dragged thru.

 

I now realize my mistake in using the high pressure car wash, lesson learned, and thank you guys for the heads up on the fuel lines and electrical connections, that was already on the to do list, already got bucket and sponge, lol, and this wasnt an automatic wash just hand held hose with pressure,anyway thanks guys and be safe out there

 

Aw man, that ruins it! I wanted it to be the big automatic kind with you wearing either rain gear, scuba gear, or shorts & flipflops.

Giant brushes knocking you all over the place, then you and the bike come out with the waxy sheen.

 

Get a twofer and conserve water. Its genius! I would patent that

 

I was giving him credit and assumed it was on a flatbed or trailer, and took that thing through the auto wash...

 

Seven but then he was on the bike on the flatbed right? C'mon, get you entertainment dollars worth.

He is knocked off the bike and laying in the bed of the pickup covered in suds, then its blown off, then the hot wax.

 

Now you guys are funny, glad to put a smile on all your faces out there, and i'm possitive that id be bustin lines on me too, you all have fun and be safe
