Well I've had a bit of a "friday" 650
no problems that have actually stopped me riding, but a lot of niggling little faults.
600 miles - Front right brake disk warps, possibly caused by salt buildup from riding through winter. Both disks replaced under warranty.
800 miles - oil leak from sender unit in clutch plate cover. New sender unit replaced under warranty.
1500 miles - clutch sensor is not activating propperly and I couldn't start the bike without holding the clutch half open. After a week or so of head scratching the problem stopps.
3000 miles - 2 bolts drop out of the fairing, odd becuase I'd checked they were tight a month or so earlier. Replacements given FOC by dealer.
3300 miles - the gear change rubber snapps off. New one free from dealer.
3800 miles - two cracks appear on the right side of the rear hugger. New hugger replaced under warranty.
5000 miles - left indicator no longer staying on unless switch held left. New indicator switch replaced under warranty.
So far that's it .. still got my fingers crossed though

All faults aside I'd still go and buy another one tomorrow if anything happened to this one (and the 675 was not out yet

)
