    GS450L Fuel problems - HELP!

    Well, I really don't know where the problem is coming from. I am hoping that the combined expertise of this board can help me out!

    I have an 82 GS450L, and it started giving me problems after it sat for a couple months with no use.

    The bike had been starting with difficulty in the morning, usually sputtering and barely idling before finally catching and running well. But one day as I was driving, it started sputtering, and then died. I had to push the bike about 3 miles back home, which was not fun.

    I disassembled the petcock, cleaned and inspected it, and reattached it. Still didn't want to run.

    So I removed the carbs, disassembled them, cleaned the very dirty screens inside, and reassembled them.

    Which brings me to today. I put the carbs back on, charged the battery up, inflated the tires. And then it fired right up! NICE.

    Well, about a mile from home it started to surge. It felt like giving it more throttle was doing nothing, and it soon stalled. I have to go down and push it home in a little while, right now it is in a parking lot.

    So, any ideas what the problem could be? I've cleaned and inspected the petcock and carbs, checked all the fuel hoses for cracks and leaks. I'm at a loss. Help!

    Sounds like you got something in your fuel. The screen had to get dirty some how. I would check your tank for any debris and make sure that you are getting good fuel flow through your petcock.

      I would get a new petcock and check the tank for rust.

        My vote is bad gas. I had the ame thing pretty much happen to me a few years ago. Drain you tank and put in a full tank of gas you can trust.

          Well, I was doubtful. But after draining the gas, and replacing with new gas and some fuel system cleaner, it has been running great.

          Thanks for the advice, I am out riding and enjoying the beautiful fall weather!
