Trimming core line length

I have a core sensor 3 bar and the front lines are a little bit stretched. Adjusting them in the usual way, in my backyard, I noticed that the pigtails are unequal length. The front lines have significantly longer pigtails and the real lines. Should I be attaching the end of the lines themselves as shown in the photo or the ends of the pigtails in order to get an equal length for the lines.

Thanks in advance

Your steering lines have shrunk, not the center lines stretched

Yes, from the end of the pigtails.

Hi SavageCarrot,

Kamikuza is correct, lines shrink. Check out our in depth tutorial about this here: www.kitebud.com.au/kitesurfing-online-courses/kitesurfing-line-tuning/

There are multiple way to fix this issue, all covered in our video.

Looking at the wear on your lines, probably a good idea to replace them as well

Seems like the front line pigtails have stretched. you can see a narrowing in the stretched section. They are meant to be the same length as the rear line pigtails.

Probably the lines would have all been equal length originally and the pigtails likewise. Calibration could have been done with or without the pigtails attached. Now there is inequality in the lengths you'll need to include the pigtails in the calibration.
Just move the knot or add a knot to make all to the required length to tune the bar. It doesn't really matter if lines are stretched or shrunk as long as the bar is calibrated, and utilizing different anchor locations on pigtails is a simple way to achieve that.

That looks like a really **** splice. Are you sure those aren't DIY?

No. They are the originals from Core.

I did eventually get this answer from core however which answers my question.

Thanks. This is exactly what I did

That's a knot on the center lines? It looks like the bury on the splice has failed somehow and the knot has started sliding, or the line has stretched.

Looks really crap to me, too short to be safe. Make your own and do it properly.

If you look at the Core website: store.corekites.com/collections/sensor-2-spare-parts/products/sensor-esp-connector-set

They only splice on one end where they have loops to knots. If I remember correctly that's the front line connection so its less likely to shrink anyway as it will have most tension whilst flying. Remember that the knot is to stop the loops on the kite slipping off so the breaking strain shouldn't be affected by adding a knot. Given how thick those connectors are, you could possibly get away with moving the knots but for the cost you might as well replace (might be worth checking the lines too at the same time though).

The genuine core ones are stitched on the splice. Do you think its worth stitching? I assume it's to stop the splice from moving when you regularly remove and add the pigtails to take line extensions on and off?

Based on the picture of the new pigtails in the link the new ones look the same unequal length as the original posters old ones ... once the looped pigtail is inverted on itself about 20mm is lost in addition to the already apparent difference in length. I'd be buying a different brand or making my own.
