YZ-2 suggested spares?

[The Doctor]

Hi guys, my YZ-2 is on pre-order (yipee!) and I wanted to ask you whether in your experiences so far there are any spares you would recommend having in the pit box just in case of a breakage.

I tend not to be a car breaker, but I don't want to get stuck without a spare part at a meeting, especially considering these are still fairly new kits and there aren't too many around just yet (especially at club events).

So far I've only ordered a set of solid drive pins (because I'm not a fan of the roll-pin type which comes as standard) and some Yatabe springs for tuning purposes.

Cheers all.
