im trying to trouble shoot rattle on start up on my 2008 roadking classic cant seem to here where noise is coming from i was thinking lifters but dosnt sound like top end what i have read on forum so far im thinking maybe compensater also seems to shudder somtimes when pull in clutch and come to stop.noise went away last season then started up again. when i took it to mechanic last season it didnt make the noise but he suggested lifter replacement. anyway to tell where problem is before chasing it with new parts. oh ya bike has 21k kilometers

 

Engine stethoscope or makeshift stethoscope may narrow noise down to where it is coming from. Couldn't hurt to open things up and look, don't have to throw parts at it, just look and clean, etc. Stock comp still or SE?

 

i had lifters and pushrods replaced fueling lifters and s&s pushrods .sounded great for about three weeks then noise come back on start up from time to time but not on every start up. also had mech inspect comp said all was good.could timing issues make valvetrain noise

 

Just ride it, when the noise becomes more consistent use a 3ft length of 5/8 heater hose as a stethoscope.
