Well anyway when you have a moment take the fat end of a butter knife and hit each spoke with the fat metal end and they should resonate about the same, off a little OK. But if there is a big difference like a thud, no one has services those spokes in at least a 2000 miles.
This is a spoked rime right? When was the last time the spokes were tightened, all should sound the same when played? Followed by truing and balancing. Then ride it and see.
good point, but when I had the bike serviced by a reputable mechanic he also, without asking, checked the spokes for me and gave them a 'clean bill of health'. He suggests that replacing the front guard, heavier fork oil and ofcourse avoid going over 140 - which if we were law abiding wouldn't be a problem - the max speed in NSW is 110 - unless you're a learner then you're restricted to 80.
