Re: Something Old Something New
Welcome to the forum. That is a classic bike and a great foundation for a motorbike.
Don't take the speeds you see posted here too seriously. Some are obviously overstated. 25/28 is a good figure to shoot for. Those 35/40 speeds are guys with small rear sprockets and maybe some engine mods, and a little wishful thinking to help. Keep in mind it is a bicycle, not a motorcycle and 25 to 30 on a bike is a good safe speed. Your weight and sprocket size will impact your top speed. What sprocket are you running now? Also you'll notice the engine will run stronger after the initial break-in period. The rings will seat and compression will increase boosting the power. Good luck, ride safe and keep us posted on your progress.
