Bought my other gas saver last month and finally put it on the road today. Its a Lifan 200GY5 enduro bike. Its a 2006 model showing 6600 on the odometer. The previous owner used the bike off road all the time...mud under the seat, cracked fender, broken turn signals and mirrors...so I've been checking a lot of bolts and bushings to make sure its good...so far its not bad. I bought it for $500. Just took my lifted Jeep off the road today so it'll be neat to see how long it'll take for the bike to pay for itself in fuel savings.
