New Limbs caused a yoke tuning question

[PurpleDriver]

So the limbs in my SBXT finally gave up the ghost after 14 years. Took the bow to my local shop since I’m the original owner. Limbs were covered under warranty but had to pay the shop to install them. I don’t begrudge my local shop a little revenue, but shouldn’t a manufacturer pay for labor on a warranty claim?? Bow shop owner said “Everything lasered just fine and the bow is in tune.” So I knew I’d be tuning the bow as I always do.

Anyways, here is my question for those who have time tuning experience on a single cam. BS tuning at 20 yards gave me this group (1st pic) in first photo so I backed up to 40 yards to fine tune. Shotgun group. Repeatedly. (2nd pic). After four adjustments I ended with 4 twists to right yoke and 4 I twists to left yoke. Gave as good of groups as I can shoot at 40. (3rd pic). But my yoke looks like this now. (4th pic) maybe two twists total in left yoke.

Is this safe to be so “untwisted” on the yoke?

the setup is:
SBXT 28.5” draw 71.5 lbs
Axis 5mm 340 at 27.5 carbon to carbon
50 gr brass insert
25 gr iron will collar
100 gr field point
X nock
3 Blazer vanes

I expected to get underspined indications because I am on the edge according to charts, and I have the IW 15gr steel inserts to address that, but bow tuned fine so far.

I will be walk-back and BH tuning this week.

That should read yoke tuning, not time tuning

Yoke looks similar to both of my bows. Not a problem.

Non issue

Looking at your first pic I would guess that a 1/2 or full twist to the right yoke would have cleaned that right up. 4 twists would be WAY more twists than needed IMO, and not sure what you were saying "After four adjustments I ended with 4 twists to right yoke and 4 I twists to left yoke". What did you do with the left yoke? And if you're RH then the left yoke should always have less twists in it than the right.

Thank you all for the feedback.

5miles,

Sorry, lots of spelling issues in that post.

I ended up with 4 twists to my right yoke and 4 UNtwists to the left. Just to clarify, the first pic is the bare shaft group at 20 yards, then the shotgun grouping is my first bare shaft group at 40 yards. The final group is my last tune at 40. That group is laying all arrows together within an inch at 20. I was trying to fine tune by BS tuning at 40. I likely overcomplicated it. Good to know about the yoke twists given that I am RH. At least it was in the right direction!

I’ve never yoke turned before and was watching the Gold Tip series on how to do it seemed to say anytime you twist one yoke you untwist the other. Do you do it differently? And if this is where the bow ended up tuning would you think there was another issue?

You don't need to untwist one if twisting the other.

Awesome info! That’s why I asked. Knew I was more likely lucky than good to end up in tune.

I’ll keep things where they are for now. Just did some shooting with BHs and they impacted right with my field points out to 40. I’ll have to go to my local outdoor range to get out further than that, but looks promising.

thanks again to all!
