I have a GS500 and engine starts fine with choke on. But once i touch the choke or throttle and it dies right away. The bike has been sitting for two years with fuel stabilizer. But I have already drained the fuel in the carb and the fuel tank and put it fresh fuel. Does that mean i have to clean the carb ?

You may have plugged up jets. Need to have the carb looked after professionally. Chemical cleaners may help but somethings need a personal touch in cleaning and possibly require parts replacement. Fuel injection is better in this circumstance, fewer parts and simpler operation.

Nothing is worse that trying to make a left turn at an intersection and the bike stalls with oncoming traffic.

I'm no expert on carbs, but if it was sitting for that long I'd start by cleaning them. There are links to instructions somewhere on BCSB or you can Google it. Throw some fresh fuel in it, and odds are it'll run.

You said it dies only when you release the choke or touch the throttle, does that mean it will idle forever with the choke on?

Have you checked the petcock to make sure it's set to 'ON' or 'RES'?

How long have you let it idle for? Have you tried turning the choke off very, very slowly to see if it will hold idle normally?

I remember my GS500 used to die when I touched the throttle or turned off the choke quickly if it wasn't warmed up enough--the motor didn't like to run cold at all, I needed choke even in the summer

Just curious, I've read that adding Seafoam can work wonders for mild cleaning jobs...how much do you add in? half a can?

Fresh fuel iliminates that issue.

The pilot circuit is plugged most likely.

Fuel stabilizer is great, but you need extra for 2 years, AND it does nothing to stop carbs from clogging up. The problem with the Seafoam fix is if nothing is getting through the pilot jet, it's hard to clear the blockage.

In the end, I think they will come out and get stripped, but why not try the foam, and let us know if you have success.

ya..... the bike will idle forever if i dont touch the throttle... however.. i tried turn off the choke slowly but it dies half way. Also the engine runs for a good 10 mins so i think its more than enough time to warm up the engine. I suspect its clogged primary pilot jet... anyways... i will remove the carb and check if it helps...

thanx for the help guys
