    Welcome Hob11 to the HDTalking forum. Bad gas initially will show up as poor running, missing and coughing like depending on how low the initial tank was before the fill with bad gas. Bad gas may be laden with water, or particles of rust and dirt, so inlet fuel "sock" in the tank of your bike could get clogged. :newsmile061:

    As stated above the only way to fix it is to drain and refill with good stuff you may also want to remove the fuel tap and clean the strainer

    I have seen bad gas do many things, from stalling the motor when you try to open the throttle to chugging and stalling, to just not allowing the motor to start at all.

    As stated, remove the bad gas and replace it with fresh stuff. If your on the road and happen to fill up with bad gas, sometimes a bottle of gas treatment will get you through that tank and not leave you stranded.

    I always try to buy from national brand gas stations to reduce the risk of getting cheap or stail gas.

    I had an experience with a load of bad (also stale) gas once. No matter how much I diluted it with good fresh fuel, it just kept running bad. Until I actually took an electric pump and pulled out all the fuel from the tank, the engine ran terrible no matter how much good fuel I added. I was very surprised about that..

    Sea Foam fuel additive will help and possibly cure problem.
