Dragstar 650

Dragstar 650

 I found that my Draggie Dragstar 650 vibrated a bit in top at normal A road speeds of about  however, the engine then seemed to smooth out again when you reach motorway speeds of (or it might just be that you didn't notice the vibration at higher speeds because of the higher revs and wind noise etc.!) I have heard it is possible to cure the vibration by installing a supercharger.
