100+mph for about 20 minuites.? the problem i have now is that when i pull the clutch in it makes a funny rattling noise, and even when i dont touch anything and the bike is running i can hear a weird rattleing near the clutch area (where you put the oil in) but it gets worse and louder when you pull the clutch in, the bike has recently been re-built becasue of the engine blowing up! does anyone know what that ratteling is and how i could fix it, thank you for your time.
