few questions about issues im having completely new to bikes
sv650s 2004 31k miles.. i know its fairly high
1. one day my electrics died, and wouldn't come on atall, few hours later all fine ( green plug fine.. no fuses blown )
2. bike vibrates excessively in my opinion compared to my friends newer model
3. the revs are never consistent in my opinion. i feel a little bump every so often, best way to describe the feeling of someone with a heart murmur, just skips a beat or beats too weak or low at times.
4. should it be idling at 1? feels weak i just wondered if thats a normal idle may adjust the screw

thanks for looking guys any help/advice would be great
