There will be three of us with YZ2's coming from Reno for the race at A-main this weekend. I will be on a secret mission to kick your horse and steal your secrets so I don't have to turn my head or wonder what you're running.

I once got whiplash from turning my head so hard wondering what clint was running. I couldnt drive an automobile for a week and had to ride a horse to get to the track. Someone tried to kick my horse but my horse reared back and drooped him.

Just picked up a YZ-2, I can't find if there is anything special that needs to be done to move the shocks to the rear of the tower. Also, what weight diff fluid are you guys running for medium bite.

Thanks!

Ok, I was reading through the manual online and didn't see it. Thanks for the quick reply.

I am not a huge 2 buggy fan, but like to have on in the stable to play around with and keep my skills sharp. (Much prefer nitro 1/8th scale). With that said I would prefer the ease of maintenance of a gear diff. Even if I have to sacrifice a little performance.

My home track is very high bite though.

How are you adding droop? Looking at your last setup sheet you posted, you are running 2mm spacers in the shock. Are you unscrewing the eyelets? When I compared my shocks to your setup sheet I was very close, maybe a 1mm shorter in rear, but a lot shorter in front on the total shock length. I have 1mm spacer in front shocks. Does that seemingly little amount change the handling drastically?

I went ahead and ordered the ball diff too. I'll bite the bullet if I have too.

Masher, you probably have a sense of this already, but you may be running your ball diffs too loose or not breaking them in slowly enough. Even if you're an old had at this, it's helpful to periodically have a friend check your diff to see if your diff feels right to him.
