  • 650sx cutting out

    I have a stock 89 650sx which has always ran great. The last time a took it out it would run fine then just die. I could start it back up and run for a little then it would die again. Could this be a bad ground or a weak battery. It is a low quality walmart battery.

    It certainly could be, or you might be siezing -hard to say without info. Did you test the battery voltage and do a compression test?

      Have not done either what would cause it to be siezing. It is still hooked up to oil injection, but I beleive it is still working.

        There are many causes of seizure. If you see a drop in compression you will need to pull the engine and tear it down to determine the cause.

          I had the same problem with a 900 zxi...it turned out to be a bad check valve in the fuel tank system....i threw it away and it ran great!:)
