Side Stand Cutout

The bike is fitted with a side stand sensor which prevents the bike from running with the side stand down.  Many people are ittitated by this behaviour.  It is easily disabled, by removing the fuse located in the fuse holders behind the seat bum pad, towards the center line of the bike.  The light on the dash still works, so you have a visual warning that the stand is down, and the stand itself is obviously designed to retract quickly and easily if the stand is accidentally left down, and the modification is very easily reversible.

Opinion is divided as to the benefits of warming up the motor before starting off, especially with synthetic oils, so don't run the bike too long on the side stand.  It is convenient to be able to leave the motor running, however, if you simply want to get off the bike briefly to open or close a gate for example.

Another issue is the switch itself - on some bikes the switch on the stand end has become faulty leading to the engine cutting out with the stand up and riding normally.  This seems in many cases to be vibration sensitive.  I don't know if this still happens after you remove the fuse, as I have long since removed the fuse on my bike.

From Martin Damsma comes a further warning regarding the cutout relay itself:-

"Removing the fuse won't always help as we noted with Marnix' 650.  In this case the side stand protection relay appeared to be broken.  This caused almost the same effect (engine cutting out with the stand up and riding with throttle well opened).  Removing the  relay (situated in the tail end, next to the injection-ignition system) by connecting the two white/yellow wires solves the problem, and results in the same effect: side stand sensor disabled and light on the dash still works!"

Side stand angle

The side stand on the 668 leaves the bike standing very close to vertical as supplied, even on a truly flat surface.  The 668 was originally designed to have taller 70 profile tyres, but this was changed early on as a result of testing and comments from reviewers who thought that the bike would handle better with lower profile tyres.  As a result the bikes mostly come fitted with 60 profile tyres. This meant that the bike stood more upright on the side stand.  This, coupled with the stand not not coming very far forward, leads to the bike being potentially unstable when on the side stand, leading to the possibility of the bike falling over.

To correct this simply remove a small amount of metal off the side stand mounting bracket, allowing the stand to come further forwards.
