Bought a 2008 benzhou moped thinking it would be a cheap vehicle with good gas mileage. Drove it for a day and it broke down. Whenever I gave it gas the wheel would not turn and it would make disastrous metal on metal grinding noises. so i took the casing off to have access to the belt. All is in tact except a bearing that is in the gear box behind the rear pulley for the belt drive. i tried to take the rear wheel off to gain more access to the gear box but the bolt will not budge. is the rear wheel reverse threaded? how can i fix this problem? any information would be much appreciated.

This applies for any vehicle. Most of us know that gas prices arent exactly cheap right now and so we accomodate by purchasing cheaper gas, but here's some good info you should keep in mind. Fuel currently is mixed differently than it was back when there was the option for leaded gas. the past years low octane unleaded gas was cheap but well mixed and made, so most vehicles ran well off of it. Nowadays the mixing is different, and gas is more expensive. the low grade gas back then was good on cars and the newer gas not so much. our mid grade gas is the same as low grade from then. if you want to make your car run better, avoid going to arco, safeway, or any real cheap gas station. they water down their gas to make it cheaper, and its lower grade than most others, so instead of penny pinching, give your vehicle a break and instead of settling for low grade, pick the mid grade gas from stations like Shell or Chevron. i guarantee you will notice a performance difference and sometimes a gas mileage difference, especially in older vehicles that were built to run on the low to high grade unleaded of their times. its definitely worth the extra 10 cents.
