i brought my yamaha jog r aircooled off by crony who had it for 2 period and he had no problems with it at all and now i eff brought it and ive been sport it for most 6 months now and i couple it the travel is so slick and conscionable a prefect soft bike. extraordinary for throwing into the corners but as they say its "yamaha" haha. i human only had the folowing; technigas fatigue, new rollers, partly desrestricted and the carb upjetted i can easily get 50 and propulsion it at 53mph. everyone says that at 53mph its gonna depart up but it truly doesnt safe same it, it sounds suchlike its going 30 because the engine isnt sweat. the cycle is litterally perfect i enjoy it so often it handles same a ideate and beats most of the geared bikes that i now. you should buy one they are perfect plyus its yamaha. one problem because ive had the carbs upjetted it drinks the supply.
