dear all, 
 
i have just purchased this bike -  
 
the clutch is sticky - i think it could do with a service.  i wanting to get my hands dirty - what should i do for a basic service? 
change the oil, filter, plug etc? 
 
where is the best place to get parts for my bike - i am based in north london. 
 
worse case - who should i go to for servicing - i need someone who is cheap but good. 
 
many thanks,
