Mine just started squeeking too (just after I got back from BC Ged, maybe it is your dirt up there )

Didn't Beaney mention wearing out the yoke to the point that the hole was oval, or something along those lines..... (I'll search)

Found it...Post #4560 http://www.advrider.com/forums/showp...postcount=4560

If you read the next few pages, I asked what components he used to "remedy" the situation and if I recall correctly, the solution involved expensive rally parts."
************************************************** ************************************************** ***********

I say:

Brad et al,

Brad, ya....musta been the BC silt that made it go "squeak"

My preliminary research via my friendly KTM shop says that to replace the entire linkage is about $200....not just the bearings. The "ovaling" identified in Uller's comment would be solved by warranty and/or non-warranty replacement of the entire pro-link suspension.

What causes the bearings to dry out and/or the ovaling???? I dunno: ....powerwashing, riding in lots of dusty conditions, inadequate grease in linkage from the KTM plant, alien pranksters.....or poor metallurgy ??????

As some/all of these bearings are needle/roller bearings, my experience with those (Husky 350) is that upon dis-assembly, the garage floor is littered with needle bearings and me crying .

My next step is to ride some more until the end of October and see this as a winter project (after 3 weeks in Mexico on a rented KLR....). Hopefully the squeak won't turn into a clunk in that time.

Stay tuned....more info/opinions welcomed

Nope, but I can tell you I will probably make a quieter insert for the LV at some point.

I've had a couple of FMF's on different bikes as do/have my buddies and the consensus is that they're just too loud.

Thumbs up to Akro or Wings (which I'm running on my 690)

Need new rims 2012 690Enduro$

Well, front anyway. Bunged it up on a slam. Anyone already replace theirs? I'm thinking Excel with existing hub and spokes (they're OK). What do you think-rim? stainless spoke? hub? color? Let's Go!.........

My first 690 had the Q4 and the one I am on now has a LV. The FMF Q4 is quieter. We recently welded a turndown on the quiet insert and they are now comparable.

The FMF Q4 is quite. It was developed to meet the 96db US Forest Service mandate. I don't think the Akro or Wings would pass that scrutiny. I could be wrong though.

Woody's is legendary to be sure and expense doesn't concern me but might be overkill for me. And TCR rims is well known too (I believe they do many for Pro Baja racers). But I'm looking for recommendation on the rim and construction themselves.

Got the head off and the old valves out. Was pretty easy, don't have to drop the motor to do it. I have to stop because the stupid valve "kit" didn't come with the damn collets. So now I have to wait a week for $12 worth of parts before I can put it all back together.

The valves really didn't need to be replaced, they're still within spec but the kit was cheap ($200) so what the hell. The valve guides are fine as well. Gonna get the head bead blasted then install the new valves.

Here's a pic of the head, bunch of carbon build up. Not as bad as my VStrom that I had to replace a con rod and valve seals on last month, but still a ton of crap on there.



The valves were in spec and really only needed some cleaning, especially the exhausts.

I think Woody's stuff is more hype than anything. KTM factory wheels are not blinged out and "superlaced" and they last a long time. The only thing superlaced is the kool aide

All 4 valves were all below the tight spec when I checked a couple weeks ago. I had set all 4 in the middle range the last interval. Seemed like a drastic change in only 6K miles. That and I've pretty much flogged the ever loving shit out of the motor. Spends most of it's time up near redline.

My Wings setup is reasonably quiet unless I'm revving the sh*t out of it, but it works quite well with the quieter of the spud/spark arresters in.

Opinions on the loudness of one system versus others may hinge on things as simple as their current state of packing.
After two full seasons on the 690, mine's ready for a repack.

The Q4 is almost quieter than stock. It has tested around 89dB on every single ride I have used it on.
