I have 2 drifters 99 and a 2000 my 99 has 23000 miles rides great my 2000 has not be riden much 5000 miles only a few hundred in the last few years. I bought it from an older man that did not ride it very much. I have a slight vibration it goes away when the clutch in so I do not believe it is tires. Any ideas??
What kind of exhaust? If it is aftermarket, that could be your vibration. The stock exhaust is rubber mounted, aftermarket is rigid mounted.
