c hings which clutch should i be using. i have a rb concept engine.
which clutch is good buku werks or Fioroni ??...
also if i use the rb engine can i still use the factory rear muffler?
thank you
is the spring not installed properly for any reason? my v1r uses similar clutch but has no such problems. please note run-in means low rpm. if it breaks after run in, then all similar clutch will break when engine runs.
