Well I Recently got a free moped from a guy that my mom knew at her work and I have a few questions.<br>Well the moped is a 1982 C70 Honda passport with a 72cc engine. Ok in the manual and it says that the mopeds top speed it 46 mph. The spedometer goes up to 55 and has markings a diffrent colored lines under the numbers of which gear the bike should be in for going that speed. The markings are as follows<br>0-11 first<br>12-26 second<br>26-46 third<br>well my problem is I cant even get it to go past 28mph. Does any one have an idea what could be wrong?
