Title: 690 Clutch issues
Post by: Dwerg on February 02, 2017, 10:12:48 am
Has anyone had issues with the clutch on their 690? Mine has a range of different behaviors from slipping at high revs, dragging when the bike is hot, not releasing when pulled in while standing still for a while, very sticky gear changes.

Any advice? I just want a rough idea of what I'm in for before taking it to the shop.

I'm on second clutch in about 10k km. My understanding is that there is some construction bug in the 690 clutch, but it can be relatively easily rectified. KTM Pretoria (not sure which one) has solution for that - I asked Runner to check with them and do whatever needs to be done to sort it (don't know what specifically it is). He did that, but I haven't ridden since July last year, so not sure if it works. It was recommended to me by somebody on this forum in one of the threads here - just don't remember where and by who.

Maybe check with Runner what he has to say (mine was also slipping) and take it from there.

Ok so I shouldn't feel too bad then considering my bike is on 24 000kms  ;D

I'll go make a turn at Trax and ask them about it

How old is your oil as your clutch can be affected by the condition of the oil and the quality.

Then again I'm on my second clutch in 20,000km and change oil every 5000km and use Motul 10W60

Oil is 1500 odd km old. Castrol racing 10w50. Symptoms have been there on and off before the oil chamge too

Try a mineral oil or semi synthetic like Motul 5100

Post by: Xpat on February 03, 2017, 10:36:24 am
Not sure it is oil issue. I would give a shout to Runner and ask him what he did with my bike (just mention my name/WD name). I am probably wrong, but I think it has to do with some washers or some such - it is design weakness as far as I understood it. Somebody told me that KTM Pretoria (I think it is the one in Centurion - not sure if it is Trax) had solution for this, which I told Runner and I think he called them to ask what it is.

I may be wrong, but I don't think I am...

Also doubt it's oil. It was also happening when I was using Liqui Moly/Motul. It's just gotten progressively worse

I'll try to take a drive through to Runner. Good excuse to go see the new shop

Debatable. Keep in mind the 1st 15 000 odd kms the bike did was training for and riding Amageza so going by some of the other replies, mine lasted pretty well. To me a clutch is a consumable on an off road bike anyway. The bike is on 34-35k kms now.

Hmmm yeah look not bad at all, Maybe one should do clutch, Battery Fuel Pump and Rocker arms at 30 000km service and be done with it.

 :imaposer: If it makes you feel better then use it  ;D I'd better take good care on my 690's clutch after hearing that quote.

Maybe chat to GJ on the forum, I know he discovered an aftermarket clutch kit for the 690 from some random supplier. He had to change out one during one of the stages of the Cape Epic last year on one of his work bikes, pretty simple procedure if you don't strip one of the clutch bolts like @WildWood did  ;) ;D

It's ok, At least you have a 690 to make up for the Hilux. ;)

I don't think it's so bad since it included the labour and stuff.  That's probably more than the clutch itself?
Obviously still expensive but yeah, it is 35000km of hard riding I guess.

Nope, I used one that gave a Global Shipping Program option.  That is a courier service (in this case by DHL) and bypasses the SA Post Office.

There will be VAT on the purchase as well, so it is actually 15% more than shown.

So a mate of mine 1300km  clutch gone.
We did do lots of constant sand and he is quite new on the bike and sand.
So bike goes in gear but when you let go of the clutch the bike just revs or idles as if in neutral?
Clutch gone? Slave Cylinder issue perhaps causing this or was he just riding on the clutch?

Dunno the 690 but if it's anything like the 701 then the gearing is too high for technical stuff, or way too high!
Yer mate better change, like in fix, that?
Sure, a clutch is a bitofa consumable, but 1300km's is silly.
If he keeps doing this then a Rekluse is for him, but mind, a shorter gearing still will help!

Sounds like a slave cylinder issue to me. Oberon slave for the win apparently. I am contemplating buying a Oberon slave for my 701 as a precaution.

You can order directly from Oberon website. I am thinking of going that route. I have not checked shipping though. This is also an option: https://www.cjdesignsllc.com/

Definitely a bit too high and the 701 (2017 onward) is even higher since it makes the torque higher up than the 690. I was even thinking of gearing mine down 1 tooth in the front.
He is new to sand riding though so was probably using the clutch / riding on the clutch for probably about 20km straight in the heat. I would have still thought there should be more life in these things.

@BuRP The Recluse is definitely a great option for him I reckon....I'll mention it, and this thread to him. Recluse / Oberon slave Cylinder is probably the way to go. What effect wil lthat have on Warranty though?

I'm keen to maybe do a precautionary as well.

I doubt that it will have a negative effect on the oem warranty. The oberon slave has a lifetime guarantee though :thumleft:

As said, a Rekluse will help yeah, but it may slip too much with the std (read: waytofrikkenhigh!) gearing.
Drop a tooth in front for starters, he may be able to actually ride rather than slip his way?
Geez, 20km's slipping a clutch will surely give off smoke signals  :biggrin:

Edited: he better put new oil in asap!

since it makes the torque higher up than the 690

Reading that bit again - nope, not with an open (cat-less & look-through!) pipe and a foam filter, the amount it has gained at the bottom is beyond belief: it wheelies everywhere, simply off the throttle!
I've got the BoosterPlug also (to enrich the mixture a little bit when in open loop) but I can imagine that with a PC-V it becomes even more of a hooligan.

Post by: BuRP on June 19, 2018, 10:24:55 am
I had a Stealth pipe from Pretoria made, a bit longer than their usual length, the carbon tip 'ends' right next to the std taillight.
It's a 48.5mm diameter hole straight through hence soundwise a bit rude - but it made a huuuuge difference to the stock-standard bike, in fact I pulled a little wheelie out of their workshop surprising me, I wasn't trying at all.
Yoshimura has the same design, a longish big-bore pipe, cat-less of course, and it ends at the same spot - so I requested them to make same.
Superb quality, the welding itself pure art (stainless btw), at a very reasonable price, was R3300 I think, and took a morning only - Happy!  :thumleft:

The Akrapovic pipe Husky offers I do not like for it has two small pipes as 'end'. This means this is a restriction, not ideal for the pressure waves - but it will be quieter probably (lol, anything is  ;) ).
Yoshimura, also a company knowing how an exhaust works, does not do this, plus they made theirs longer, for a reason no doubt. It is why I asked Stealth to copy this, and do not regret it at all. I had my F800GSAdv also fitted with a Stealth, plus they 'gutted' the std pipe (take the cat out). This all worked very well, was reasonably priced, and the welding quality is rather special.... so I took two cars to them as well.
I can recommend them, and do.

Great thanks! Gooi some pics on the Husky thread! I have the akrapovic pipe on mine. I know the baffle with the 2 smaller holes can be removed to provide an open pipe. Would be interesting to know the effect the baffles have on the performance of the bike.

Apply that to the 690 or pre 2017 Husky and it will be lower still. It is what it is. The Husky 2017 and later has the Duke engine. Smoother and faster up top but not as much torque down low and 7kg heavier. Seemingly minus the potential rocker arm issues.
I have a Wings pipe on mine and even that made the low down noticeable improvement. Itís insane how hey plug it up to meet the emissions guidelines. So I agree with you that the pipe and air filter improves it significantly. I was quite surprised by how much. Itís literally a seat of your pants noticeable difference.

A better pic, also shows the R&G TailTidy mounted.
The latter is a nice unit except for the fact that the space between bike & light is open, too open - the rear wheel will throw stones & dirt in here, and all the wiring has to live there, not good.
So I've closed it by mounting a rubber sheet in it, just visible in this pic, invisible when the tailpiece is mounted.
Lots better!

If only it was that easy! On theses akras you have to drill out the pop rivets, as the bolt holding the baffle is not reachable from  the outside. Drill out the pop rivets, remove carbon end piece, take out the bolt and remove the baffle. Then drill the carbon to make the bolt accessible in the future and re pop rivet the end piece back. I will do this somewhere in the near future though...

Blikskottel, that's an operation in itself!
I've done this, on different akras, and all that was needed was 1 sharp chip with a chisel, then a little bolt could be undone.
You better get some decent quality poprivets first, but do let us know pls, as I said I expect this to make a noticeable diff.

Wings Exhaust: Take out grommet, long Allen key remove baffle and choose one of the other  baffles supplied or out. Put back tighten allen put back grommet. 30second job.  :D
I must admit that I like the sound of the Akra a little more than the Wings. Although there is not much in it the Akra does a have a Deeper sound - which I prefer to the throatier rasp  of the wings.

The Wings I think looks good though.

So a mate of mine 1300km  clutch gone.
We did do lots of constant sand and he is quite new on the bike and sand.
So bike goes in gear but when you let go of the clutch the bike just revs or idles as if in neutral?
Clutch gone? Slave Cylinder issue perhaps causing this or was he just riding on the clutch?

Sounds like a slave cylinder issue to me. Oberon slave for the win apparently. I am contemplating buying a Oberon slave for my 701 as a precaution.

If it goes into gear OK, its not the slave.

Yeah my thought too - friend has been away on business so haven't checked it yet. I really want to see what they say.

So his bike's Clutch plate and the Slave cylinder went. What would go first in this instance?
I must say this must be some new record. 1300km later?

With the right type of abuse you can cook a clutch in 20 mins

The 690/701 is particularly clutch-sensitive, and around here uite a few guys have destroyed plates on these bikes.

For camera-work in cycling/running events we lower the gearing to accommodate low-speed work.

I'm quite keen to actually drop a tooth in the front myself. Way more useful than being able to do 199kph.

I dropped a tooth on the front, it feels like a different bike  :thumleft: easier to manage in tight trails etc and still can do 120 comfortably if needed

On the 690, what rpm increase does the dropped tooth front sprocket have at 120kph?

@w@anted,

I asked Oberon, the CLU 1000 & CLU 2105 (I think, the number you mentioned somewhere - but I did get the number right when asking Oberon) is exactly the same.
I wanted to know if the dispalced volume (i.e piston diameter) was different but nope, same things.
Fwiw...

Thanks Burp

I also contacted Oberon. Received some feedback stating that the Husky uses the CLU1000, which is different from the CLU1201 due to the diaphragm design which is similar to the oem slave. But the CLU1201 also fits the husky, apparently.

Sounds about right... check the speedo because 120 comes quickly  :biggrin:

Hre's my take on gearing.
If possible at all I prefer odd-numbered sprockets, for reason they will last longer, ditto the chain.
Now the 701 comes with a 15T front, and (I think) a 46T rear.
I've ordered a 51T rear which effectively drops the gearing ~11% - which is more than going down 1T at the front (to a 14T).
I'm sure I'll like that though, more capable in difficult terrain in 1rst, and on the slab it's quick enough in any case, too quick if you believe some of my (non-riding) friends  :biggrin:
