The motor seems to regulaly get stuck on the comp stroke. I usually use the hand deco on the bars to get reliable results but this is not always good enough. I have been thru about three good batteries in four years and am now running an even larger than std battery ( bit of a squeeze ). Is the auto deco prone to wear in these things and if so, are they repairable, or do I have to replace the whole camshaft to get the needed part. I was checking out the thread about the starter clutch spring and that sounds like it would be a good fix as well.

All advice greatly appreciated.
Are the valve clearances correct?
I actually had the same problem happen over a rather short time period. It ended up being the larger cam bearing failing, which caused the valves to not open enough/for long enough.

Crash

my bike died a couple of weeks ago when I crashed into a u-turning car. Repair will cost more than the value of the bike. On the picture the bike doesn't look to bad, but after close inspection there was quite some damage to the front. Looking for a new bike :(

Ouch! Are you ok? As for value as stated by insurance companies-doesn't mean it's not worth fixing for the right person

I hope you are OK and not hurt. I wish you all well.

about the bike, may I ask what is the damage? is the frame bent? or just the front fork.

I would definitely buy that bike back if the price is right, if you can live with a few scratches that looks like absolutely minimal damage. Even if the forks, triples and front rim are a bit bent they can be straightened or replaced for a few hundred € with parts from Ebay.

2003 640 adv Starting problems

Thanks for all the response.

I have done the cam follower bearings and I keep my tappetts pretty accurate.
I will pull out the starter clutch and have a look but the symptoms are as if my battery is weak so I think that the cam/deco is the culprit.
I have an engineering shop at my disposal so I will let you all know if I can successfully repair the problem. Apart from a waterpump seal and general wear and tear this bike has preformed admirably for 62,000 klicks.

KTM 640 ADV Fuel Pump

Hello,
attached are a few pictures of the fuel pump replacement.
the new fuel pump has a different set of holes, therefore I had to create a new piece with new set of holes to attach it to the original location.
I also took this opportunity to clean and balance the carb.

I was wondering the same thing. I wouldn't do any work on that filthy bike and especially remove the carb. Good time to check the valves or reseal the rocker box while you're at it.

I admit the bike is dirty... :(

I use the bike as commuter and I go to work through the fields, which are watered therefore very mudy.
I live in a small town and work in the big city, on my way to the highway I go through the fields.

http://www.youtube.com/watch?v=0RHL2a46sOE

the bike is full of mud on daily basis.
and on the weekends I go riding with friends, so I admit, the bike does not get cleaned on regular basis...
I know, I should do better then that...

But hi, I ride the bike instead of clean it all the time... :)

Ignore the girlish observations about cleaning the bike.........

Yeah, you should'a washed it before wrenching but that's the way a properly used Adv should look like!
