I used the scooter for one and half half year, my opinion, it is a irritating scooter with very bad power, only one thing is the fuel consumption and weight that is the only one thing I like.I would like to add one thing here that other than going for the engine oil change therapy, i have a spoke kick variant, you can look at the chain slack like I did with my Spoke Kick variant. While riding a vehicle, the riders get confused in case a noise comes from the bottom of the vehicle. The noise of chain slack is almost same as it comes from the engine. in rainy season, it will make more noise and chain slackening.
