I fly Revs & have 07 models 11m & 13m plus 08 9m.
My problem is with Rev11m. In the past few sessions I've experienced a 'sticking' of the bar on the left. The usual movement up/down the bar as you sheet in/out seems stuttered on the left side. I've checked the bar and slot - no apparent catching there. The result is the kite flies as if the line is shorter and the kite flies left no matter what the travelling aspect. If you sheet in/out agressively it momentarily corrects itself.
I think it may be the pulleys but not sure. I put new kite-lines (not flying lines) on the canopy a few weeks ago with no immediate problems. At the time the kite shop guys said that the pulleys were OK. I've cleaned and checked them and they appear to run freely.
I've also checked flying lines lengths and after some minor stretching they seem OK. I also use same bar for 13m and don't have this problem so don't think its the bar/lines set up. If it is the pulleys any suggestions besides replacing with Rev parts. Thanks for any suggestions

First, your Revs must be 08 & 09 as they only came out in 08. That aside though when you refer to replacing the "kite lines" on the canopy I am assuming you are talking about the pig tails only. If you are using the same bar on another kite and there are no line length problems then I would suggest that the bridal lines have stretched unevenly. This can happen as well. I had an 08 Rev and replaced these once in 12 months of use.

The lines I'm referring to are the red and white lines that run through the pulley on each side of the kite. The ones that tend to fluff up. Same as the lines on your bar, if they stretch unevenly your kite will steer to one side.

You may be able to tell by flying your kite overhead. If one pulley is nearer the trailing edge than the other then this is the case. Otherwise take the lines out and check the length of one against the other. If you replace these it should be problem solved.

I can't explain the sticking/catching issues.

This kite might be a side-flyer. ^^^
By this I mean, all the rigging is perfect but the kite has been constructed incorrectly.
If the leading-edge seam has been sewn assymetrically onto the body, the kite will fly relentlessly to one-side.
This fault is impossible to see with the eye, you can only feel it when flying.
Even when the (deflated) kite is laid-out flat on a table, the flaw is well hidden.
The shop-guys know of this problem but rarely discuss it.
It's more common than you'd think.
It's the INDUSTRY's dirty little secret.

To check for side-flying:
In moderate, consistent wind.....
Park the kite steady at 12 o'clock, then gently release the bar.
If the kite stubbornly flies to one-side after numerous attempts......
go to step 2.
Step 2:
Replace all the rigging with new string and repeat step 1.
lol.
