Although I think i'm going to be happy with the new bike, it was not easy to say so long to the bike which introduced and took me into and through the long distance DualSport riding.
Since the very first day, she was gentle, tough and proud. She showed character, and was always strongly present the dirt soul of her... and I loved it. Unfortunately, I can't afford 2 bikes in the stable and I couldn't refuse a great offer for the 640.

Many many great rides, five years and 50.000Kms later, I let her go with a smile on her face.

Other aspect of this story is how I feel about the "KTM LC4 (640) Thread Index" and "KTM 640 Adventure owners, sign in please..." threads.
You guys have made me feel part of this community in an awesome way since the very begining. As I have said once or twice before along these years, It's still hard to believe how great is the general help will and the kindness of you inmates as a group. It's like meet you riding here or there... that's the spirit, that's what it's all about. Some of you may think "ok, big deal..." but the way this world is evolving... what you find here is just not usual anymore.

So... thank you guys for all your rider's friendship and help, and if I'm allowed to, I will keep myself lurking around just to see what's going on with you, your bikes and your trips. Not having a 640 anymore doesn't mean I can't go to the coffeshop to meet you anyway, does it?

Cheers!

.
congrats and good luck!

i too went bigger. bought a 950 and after a year 1/2, sold the big bike. it's heavy and big for my kind of riding.
today, i still love my 640, it has taken me to a lot of different places, see my sig line. it's my trusty steed.

true, the bike is transitional, one day most of us will all be switching to another one. mine may last longer since i have a spare 640a that i use as my parts bike.....

the most valuable element on this thread is the people - always ready to help and provide reliable info....

that's one reason i hang out here more than in any other bike specific thread. thanks to meat and contributors.

keep up the good work guys!...

If you bought used, do you know about any changes to the forks/ front wheel?

if my memory serves me well, the 02 adventure had a 20mm front wheel axle, and the bearing you have (old) are 26mm - so it looks like the wheel is not the stock one.

The bottom bearing and spacers are the 20mm ones. for bike 2001-2002

some bike in 2003 (sxc) still had the 20mm axle, but other (EXC/Adv) had the axle upgraded to a 26mm

same here.

the front wheel, i mean the hub, bearing and seal must be from a 525exc and using a bushing with a 20 mm bore to fit the 640 front fork.

boon boon, measure the bushing od, and if it is 26 mm, then our hunch is right.

if that's the case, you need the bearing and seals for the 525 exc, i have a 2003 (first year model) 525 exc and has 26mm axle.

NSFW, similar stories yours and mine with the 640A, will see how ends mine.
I would love to keep both, but my budget says NO.

I had an awesome experience in both 640 threads during 6 years, most of the guys here are incredible.

To save liferider from answering this, here is the PM he sent me less than 24 hours ago when I asked him the same question.

Hope you don't mind Alec.

That screen is an aftermarket tall BMW GS650.

Here it is as it comes:

And here as it looks with black vinyl :

Should I, or shouldn't I?

Hi there,

Hello fellow bloggers, hope this post is in the right place.

I need advice from the enlightened LC4 fetishist's.


I have a 1999 LC4 400D (UK) and use it for commuting and off roading. I have had the bike for 2 years now and have increased the mileage from 6500 miles in april 2010 to just under 15000 miles this week.

Untitled
Untitled
Untitled

I am very particular about oil changes and have been using 10-40w semi synthetic with an interval of 1000 miles. Over the last 2 years and 8500 miles the oil changes have generated less and less swarf and shiny broken fragments to now where there is only a dusting of metal filings and a few chrome looking tiny slivers like glitter.

The reason for this thread, well something has changed in the engine. The sound is different, there is more top end clatter. The motor pulls strong and revs freely. I am concerned that something has begun to happen, and want to catch it before it gets expensive.

This engine has never been apart, it has the old style bearing still in there.

Here are some photos of the internals.

The inside of the top oil pump.Untitled

The rotor.Untitled

The other rotor thing.Untitled

The bearing retainer inner edge. Untitled

And the old style bearing.
Untitled

Everything looks nice and new. The bearing feels tight, and spins freely.

Should I replace that bearing with the new style one. I have the parts sat waiting, but cant see any point if the old one is good.

Secondly, should I take the top end apart, the clatter must come from there. How far should I tear it down. Just the lid off. I need to take the water pump out and sort this little problem.

Change your coolant. I reckon this is the original coolant. loops!
Untitled

Hopefully there will not be any major issues, and the noise is just the engine maturing.

Any advice is very welcome. I would describe myself as a competent home mechanic. I have none of the specialist tools.

Simon.

Have you checked the valve clearances lately? Often the first thing to wear out in these motors, at anything from your mileage up, will the inlet cam follower roller bearing - you'll be able to check that out when you pop the top to take out the water pump.

Cheers
Clint

Thanks for the reply,

Valves checked 3000 miles ago. Needed little or no adjustment.

I think you are right, I will have to take the lid off and see what is under there.

Is taking the rocker cover off easier with the engine out? Or can it be done safely left in site?

Simon.

You can remove the rocker cover with the engine in the frame. Just takes a bit more work, but not much.

There is plenty of details on this site about doing the job. At 15,000 miles, I wouldn't even bother about checking, just replace the inlet cam bearing. They can go to shit VERY quickly (mine went in a just over 700 kms and caused a large amount of damage).

Have a look in the index at some of creepers threads about sealing the rocker cover and also about a bolt that can make it look like your cover is leaking).

Good advice, I have now read those threads (in part) and can see that most of the questions have been answered already. A bad time to get parts for the LC4 what with Christmas coming!

Sincrosimon, if it turns out to be the intake roller going bad have a look at this.

Thank you guys for making me check my rocker bearings! Just saved myself some serious dough, the inlet one was close to going kaboom.
