I was driving my 50CC scooter down the road today
Your drive belt snapped. If it is a 50cc, 4 stroke engine, chinese scooter, with a 10 inch rear wheel, then you most likely need a 669-18-30 belt. That is the most popular scooter belt on the planet and is available for about $10-$35, depending on the quality you want. Any scooter shop can change it for you. It only takes about 15 minutes, but expect to pay a chargeable labor rate of .5-1hr since there are unexpected problems occasionally, and there is cleanup time, paperwork time, etc. It should cost about $30-$75 in labor plus parts. Any more than that and you are getting ripped off. You may have other worn parts in your transmission such as roller weights and variator guides. These tend to wear out on chinese bikes around 3000km+. If they are worn, change them while the technician is working on it. It shouldn't cost you any more labor, just the parts, about $12-$20 for the rollers, and $8-$12 for the guides. Cheap belts last about 2000-3000km, good belts last 5000-9000km. Pay the extra few dollars for the better belt, you won't regret it. If your belt broke prior to 2000km, then you may have a defective part in your transmission, such as the rear pulley. That usually comes as a "clutch pack" and generally sells for $40-$90. If you have more than 2000km, it probably snapped just from normal wear and tear. If you can't find a local scooter shop, you can reach us at www.solanocycle.com. We can ship you any parts you need. This repair is not recommended for novices. Although it is easy for those who know how to do it, you can damage your crankshaft and ruin your motor if you do it wrong. Hope this helps.
