Default Couple of YZ-2 Setup Questions

Ran mine for the first time yesterday at TORCH. Was pleased, but the rear was a little loose. I was running Lee's setup from TORCH, with the only difference being i had the geared diff in with 3k oil.

My first question is would a ball diff of helped with the rear traction issues i was seeing?

2nd Question is about springs. When it gets a bit dryer i think i need to get harder springs, but i am confused about which ones to get. Can anyone give me an idea of what i should get for a dry astro track?

Cheers

Dave

Ball diff would have made a huge difference, I am guessing it was damp? The gear diff should be perfect in the dry at TORCH.

At the weekend Lee was using YAS Black on the rear and YAS Yellow on the front on carpet. I've also used YAS Orange front and YAS Green rear.

Thanks for this, the kit springs defo feel a bit soft for the dry. Was greasy so will look at the ball diff, at times it felt like I was driving with a solid rear axle! Doesn't help that I have been doing 4wd this winter till now and have been spoilt by lots of grip!

The yatabe springs are more suited to high grip and are a bit shorter. Try raising the rear hinge pins as kit set up has them down. I also run the rear link in the second hole as opposed to the innermost. Both these changes should help increase rear grip.

Another setup question: As I saw on lee martins last eos setup sheet he removed all the 3mm spacers between ackermann plate and steering link ballstud. What will be the effect of it ?

super responsive/aggressive steering. I've gone to 4mm after talking with Lee at Worksop to calm mine down.

Does it affect all turn or just turn in, medium or exit of the turn ?

EFFECTS OF ACKERMANN ADJUSTMENT

Forward holes (sharper angle)
• Sharper steering overall, but better and moreso for fast and gradual turns
• Better suited to smooth fl owing tracks with high speed corners

Rearward holes (shallower angle)
• Smoother steering overall but with faster turning ability
• Better suited to small, tight tracks
• Doesn’t work well when traction or cornering speeds are low

Does that not read as a bit contradictory to anyone else? Less angle better for tight corners? Surely a more severe angle on your steering would be better?

A shallower angle to me would be better for a fast flowing track with sweeping bends for stability, however that guide above tends to say otherwise.

So confusing.

Other setup guides/tips I've read seem to suggest the same as the one Neal has posted but it doesn't seem logical?

Yeah, it does read opposite, but it was from xray guide, so not surprised ;-)

I guess it needs to be tried for oneself. I ran with 3, then went to 4, and it was a little better for me at worksop. I guess its best going to 0 or 1mm to get the extreme other end of scale.
