Running in, nowadays with the perfect tolerances in modern machining,,
HOWEVER, the bikes a 2012 and cosmetically perfect but it's been on Yamahas books for the past year as their 'demonstrator', only done just shy of 900 miles but the rear tyre is down to its last mm of useable tread with obvious signs of abuse, backed up by the chamfered hero blobs. They've given it a service (Wigan Yamaha), but it's not happy with hot restarts, I'm having to roll on the throttle whilst pressing the starter although once running it holds idle.
The first thing to check is the warm idle. It needs to be set between 1200 - 1300. I suspect it's set at about 1100.Also, run some injector cleaner through it, chances are it's been sat for long periods.As for the tyre, it should never have been sold to you in that condition.Good choice btw.
