Any ideas?

Found this under the 14 when I took the dust cover off, its very clean and around an inch high - not sure if its off the bike or not? any thought welcome

Looks like a spring..

Can't place it as a 14 part though.

looks like the spring from a paddock stand - you know the wee ones that keep the hooks out

Can't place it either, but recall a mod on the seat latch that involved a spring to hold the seat up after unlocking.  You got one of those Notty?  Had the seat off lately?

Yes seat been on and off last few days ! will check that

Don't ride your bike without this spring fitted.  It's the reverse clinch throbatron valve return spring, essential for smooth running, refit it immediately.

I was going to say it was the spring from the seat latch mod...

[VladTepes]

seat latch mod? Do tell...

[KiwiCol]

It's a spring fitted to the seat latch so that when you turn the key to unlock the seat, it pops up a bit (because of the spring) enabling you to grab the seat with 1 hand whilst the other is on the key. 

Makes it easier to get the seat off.

[Hooli]

Whats the point in that? the seat is never a problem to take off anyway.

[VladTepes]

Yeah that's what I was wondering.

Enables one-handed seat removal - e.g. when you have stuff in one hand you don't want to put on the ground - just turn key, seat pops up and can use the same hand to remove.
I found it useful!
Others may not...
