Just my 2 cents worth here - Having thrown my leg over various twins through the last 40 odd years and knowing that vibrating things between your legs tends to loosen lotsa things (Ok hold it right there - we are talkin' petrol driven - not battery powered toys) and knowing that fact as you all do, and I mean all of you - it is wise not to leave it to the stealers (or forums) to check your ride for loose bits and pieces (as sometimes stated in various service descriptions) - If you want your ride to last and not fall apart all over the road when you are out on a great ride one day - perform regular, preventative maintenance - it takes 30 mins once a week for fargsake - take some pride in your ride and work on it!!
Check, fasteners, belt/chain, wheel bearing side play, oil levels, leaks (oil, fork seals) tyres (for splits etc) belt for stone chips or tears - all this can be done when you clean it! I bet half of you check your dick more often than you check your ride.
Yeah mine has been good so far, yeah i come across a loose bolt or 2 ever so oftern, im not really concerned by it as im always throwing spanners at my bike..im not loosing any sleep at all over my bike.
