KTM 640 Adventure Thread

Cool thanks guys and girl!
I have an E07 on the back too. If I can get 10k out of it I will be happy, but I somehow dont think it will happen...Helga (my bikes new name ) insists on a heavy right wrist...

Stop blaming the bike... You just have really bad throttle control...

 I always run a TKC on the front, have tried various on the back, & am happy with the Mitas EO9 ..
Running a 140 at the moment, will probably change back to a 130 again next time... & a rear rim lock helps too..

Hello Malibu, thanks, that makes sense, the previous owner told me that he topped it up with brake fluid before...that sucks!! I checked in the Manual and i saw they specify Mineral oil...eish! Thanks!

You going to have to replace all the rubbers throughout the clutch.. Sorry! 

Okay, there's no KTM dealership in Knysna or surrounds, but i got hold of a guy who knows the bikes pretty well and he told me to first drain all the brake fluid out of the system and to replace it with the correct mineral oil - if the rubber isn't damaged, things should be cool...if not, then i'll have to replace the rubbers...i did it and the clutch seems to be working as it should - will see if it lasts. But for now, i'm pleased with the result. Thanks again for your input. On a different note, what oil do you guys use when changing the oil filters? Thanks

Terrific... good news!

Try the Mitas C02 on the back wheel. I was surprised how long they last for such an aggressive knobby and they dont costs that much. The first few hundred K's they walk around a bit

Just acquired a "new" 640 Adv recently..
As i already have one, have been in the process of transferring upgrades from the old bike to the new one..
Sent the bike in to have the leo vince fitted & the carb set up to correspond ..
Well impressed, feels brilliant, sounds great, very responsive, just felt a slight leak on the pipe...
Anyways, never mind, swopped bars, & raisers, & guards last nite, started her up this morning, ( as i finished fairly late last eve)
Well, suspected all along there was a leak between the tailpiece & the header...
Sadly Not.. the header has a spreading crack around the mid mount to the frame ... I will try & Tig weld this in the morning on a very low setting.. Its paper thin, & Im a bit scared of burning through....
Will see...
Removing the header pipe is a process, which requires removing tank, fairing, dropping sub frame, ( not full removal) , & removing the rear shock, after which it is easily removed with the application of a few well placed swear words...
I am considering just going the whole hog, & ceramic coating the header as I have done with "Doris"
Sheeet, been 2 weeks & nt even a proper ride yet, as Ive wanted to get stuff sorted ..
( First priority was valve clearance as im not qualified)..
Getting frustrating now, as the old bike needs retuning for the pipe swap..)
Maybe i will have to fit the repaired pipe, just for a ride...

[Husky Boy]

Good luck dude!! Hope all goes well..."with the application of a few well placed swear words.."

Questions...

1. Is it normal for a 640 to "hunt" at idle?
I have noticed on mine that the revs are not very constant when at idle speed and seems to be quite rough?

2. When is it best to check the oil level? Hot or cold?

3. When I decelerate, the bike exhaust "pops" quite a bit against compression...is this normal or should I have the jets checked out? She came from the coast, and now lives in Richmond, which is about 800 asl.

4. How can I change things around so that I can start her in any gear? She only fires in Neutral and its sometimes not very convenient.

5. What aftermarket pipes are suitable for her, and what can I expect to pay?




6. Is it normal to enjoy a bike this much?

[Husky Boy]

6. YES it's quite normal - I LOVE my bike!!!

[Husky Boy]

I've only had my KTM for about a month - can't really comment on all of the above, but my idle speed is constant. The manual states that you can check oil hot or cold. Leo Vince pipes are very common, i got one with my bike, don't know what you would pay for it... ENJOY

Idling is rough, but not hunting as such... a bike that has come up from the coast I'd have checked anyway, jetting especially...

Check oil always on warm... i.e. 5 minutes after motor shut-down.  So all bubbles have floated free...

Heard that you need a clutch lever with the small spring in for in-gear starting, I find the spring-less ones a LOT cheaper, so I followed the wire (that wire in front of the clutch lever) through to the plug, cut and wired the ends together.  Now I can start her in gear! 

After market pipes, dunno, still on standard... Mark wants to put some Leo Vince thing on her... costa lotsa!    His choice!

Thanks Malibu,
That would make a lot of sense regarding the little spring....I changed the lever on Saturday and was puzzled when she wouldnt fire in gear like before
Getting her checket for jetting this Friday

Did I mention that I like this bike ?

Hahahahhaaa, what's not to like...   They are super amazing bikes....

[Husky Boy]

Totally the coolest bike i've ever had!! Absolutely love it!!

Popping sound normal on decompression, and if you put an akropovic on you need to buy yourself and all your friends earplugs!!! To the point of being annoying
