Bike stalls after 5 minutes

”Sounds like I'll have to pull out the petcock and try to get it to seal better by polishing like you said.“

pull it out and get new one and find something else to polish

I really like my petcock though, if I bring it over to your place can you polish it for me?

i have installed an electronic fuel valve on several bikes ao my Kawa GTR1000, which has no overflow tubes and is known for hydrolock.
Around 15$ off Aliexpress, hooked it up to a switched 12v ... Bob's your uncle.
They are not very big and my buddy mounted one on his GT750 as precaution.
Won't protect you if the petcock leaks into the vacuum hose but adds extra safety.

Hmmm that sounds like the best option, install and forget it. I'll look into that thanks!

Decisions, decisions. Also there's an "O" ring on a plunger that seals to the seat, check that "O" ring for any defects.

Will do. I'll bench test it before I put it back on the tank

Well that makes sense!

I wouldn't worry too much about engine damage. Fuel dilution lowers the viscosity, but at idle its unlikely you wouldn't have been putting enough load on the oil film to destroy the boundary layers and thus the lubrication and allow metal on metal contact.

Plus the solvent activity of the fuel probably acted as a half-decent engine flush. If it sounds like it did before when running, just change the oil and filter, make sure the carbs aren't leaking and keep riding it.

That's reassuring, yep I'll bet the crankcase is squeaky clean now lol. Changed the oil again yesterday and am going to take it for a ride today. Fingers crossed that its good to go now.

RIJKO..
Think you could post a link to that electronic fuel valve??

Cannot find the exact Tomasetto one on Ali**^&% anymore but here it is on Amazon : link
Unfortunately at 29 EUR, more expensive than when i bought it.
A search for Tomasetto EBAT0001 shows them for lower prices, hope you can find it cheap locally.

Just a thought here, if when reassembling the carbs, did you by chance mess with the idle screw? If running rich on the pilots and the idle screw set too low it will die when warmed up. Just for poops and giggles try setting the idle screw a few turns more, like enough to make it idle fast at start up and see what happens.

So I figured out the problem, I had gas in the oil and it was vaporizing when hot and passing back into the combustion chambers and running rich. Changed the oil and the problem is completely gone. Rode for an hour Wednesday and ran perfect. Thanks for the comment though it was a perplexing problem and surprising solution.
