KTM 640 Adventure owners, sign in please...

[Epoch of Entropy]

Just a confirmation question, and I don't think this is worth a separate thread...

What TwinAir part number is for a 2001 LC4 640E? 154514 or 154512? I pulled out the filter and it has the oval kind of opening.

The TwinAir application guide lists disjointed years/models between these two part numbers.

Thanks!

Hi Everyone, just bought myself an '05 625SXC which shares the in-frame oil setup with the 640 adventure and I imagine the oil-change procedure is the same. I owned an adventure many years ago and recall there being an awesome step-by-step thread on how to do an LC4 oil change including photos. Can anyone post a link?

I seem to have a slow leak from the burping outlet at the top of the frame on the RHS and the oil is coming out really clean (might be due to a meticulously clean previous owner). I'd just like to make sure that all is good, perhaps it wasn't burped properly or I need a new washer? any advice much appreciated

Give it a new washer. I've had that leak a couple of times when I've re-used the washer, usually a re-torque will sort it out though.

I found KTM do a kit with the filters, all bung washers & a filter cover gasket for an oil change for the same price as just the 2 filters separately so mine get replaced every time now.

Cheers
Clint

hi guys, my speedomter buttons are unresponsive. The display is stuck on the tripmeter view and I can't scroll between modes. Have tried taking the face off the unit and pushing the buttons behind and still no joy. Any suggestions?

My buttons were non-responsive too. If it is the new version of didplay - orange - you have two choices - get the tripmaster switch, connect it and you have your functionality back. Other posssibility is to carefully open the unit, and resolder new microswitches into the board.

OK guys, help maybe?

03 640a, 13k miles, no smog stuff, but stock carb, engine, fuel.

My bike is doing a weird fuel thing again at around 185mi left in the tank. I am puzzled by this. It runs like it's cutting out on fuel, but never stops. Not on reserve, probably still 2-3 gallons left (usually when I fill I'm filling 4-4.5gal, tank holds 7.4 or so). I've read about hiccuping, but it does not seem to be like that (maybe it is). Not sure why it'd always come around the same mileage if it was.

Anyway, the bike does cut in/out for a bit, if I just stay rolling it will go away, and tends to be helped a bit if I do a left hand turn (maybe that's just my psychological thing). If I come to a stop the bike will die during this and be a bitch to restart (usually waiting a few min works).

Here's a theory - tell me if it makes sense...
Bike is getting good fuel when the pressure in the tank can help the weak ass fuel pump. When the gas gets lower in the tank, the pump is more on it's own and doesn't keep up so well (I believe it's about carb level in the tank when it does this). The part I don't get is that it doesn't just stop working, it will work again.

My easy solution is just fill up when I'm about 175mi into a tank, but I'd prefer to ride with only about 5 in there max to not be so heavy. It's a lot more nimble off-road when it's not full.

Do I just pony up and replace the pump or is something else out there?
