New and improved KTM690 WUNDERFEST

Just free thinking here, I know, dangerous. Don't filters clog over time? By design? Do cars need their injectors/filters cleaned on a regular basis? I don't know many people who do this.

Personally I have never bothered doing much with injectors on 4 wheel vehicles, unless there was some reason like poor economy or performance, I which case I've mostly just thrown in some injector cleaner chemical. Can't say I've noticed a big change. I did have bad injectors on a 5.9 Cummins. The symptoms were that it would not build pressure on starting and quite a lot of black smoke for no reason. Having someone else install them the total was close to $2500. Searching for a vibration issue on my 990 I sent the injectors to a cleaner who produced recorded flow rates - they weren't very dirty after 7 or 8 years, but the test and clean put them back to new shape and allowed me to cross something else off the list

Back to the 690 ! This one has my name on it ! Pick it up Wednesday.

I really want a new style front fender on my 2018. They look good to me.

The internal filters clogging generally result in a replaced injector in anything still under warranty. After that, it varies by mechanic and owner's wallet. But they rarely plug within the warranty span.
There is no service schedule on them, and they are not replaceable. But could be back-flushed or U/S cleaned.

I have a 2010 Enduro r, does anyone know if that year used/came with that little triangle shaped filter before the injector assembly?

Pretty sure that year didn’t have the tiny inline filter. Mine certainly doesn’t.

I read this and thought, no way...

And yet it's true. According to Toyta my 2017 Tacoma has no service schedule for the any fuel filter. In fact the large inline filter is so oversized compared to vehicles even 20 years ago that they don't clog over the entire service life. Impressive...

People tend to lose their minds over it - particularly on motorcycles when they look in the manual and get frustrated about the OEM sometimes not specifying a service interval. But how are they to know how much dirt you're going to put in your gas tank? It's hard to overlook the fact that fuel pump failures are much more common on dirt bikes. And KTM's probably see more dirt than most adventure machines. Filters don't "just fail", they plug, and that depends totally on the dust/dirt load they see. If you remove your canister and go to a conventional tank vent, you may be drawing in dust every time you ride.

I understand your point, and really don't disagree, but if we're talking about the 690, filters can fail. It's not often, but has happened...

I have been having an intermittent stalling issue after a wash. I think I may have found the culprit!

Good find

I notice your old regulator still has the connector. I cut if off mine and used it on the new RR. What did you do? I would think it might be hard to find a new mating connector for the stator output.

What is the shifter detent and spring?

At this point the whole fuel pump and filter thing has been thoroughly beaten to death. But I have another thought on relocating the outlet filter outside the tank. I always had some concern that this left the regulator unprotected. But now it occurs to me that also puts the filter beyond the recirculation point, which is the regulator. So any crap in the fuel, brush material included, gets recirculated back through the pump....over and over and over....

So enough, how about beating up on Tubliss or Rekluse or oil......FWIW

Yes, but who disassembles their fuel pump to look at the filter?

The stock connector is unsealed so I switched it out to a sealed unit. I used a Delphi Metro Pac 280. Quality connector, not exactly small, but I found a spot where it fit.

There are other options available, but just make sure the current rating is appropriate.

The shift detent and spring was replaced when beer and my wallet were near each other one night.

Don’t know if you’ve changed filters yet. It really isn’t that difficult. Pump does not have to be disassembled. I replace crimp on line clamps with standard FI type screw on. OEM hard plastic lines can be removed with carefull application of a LITTLE heat. I safety wire the pump sleeve and carefully zip tie wiring to fuel lines to keep terminals from being pulled off during re install. Be careful not to kink lines and double check all connections. Easy, peasy IMO. FWIW

Well, we all do (sort of). Because if you own a KTM 690, the the pump filter is in the tank and inside a housing.

Good to know. How often.

Is it on the service schedule? I’m new here.

Edit - see post below...

I've done it twice in 20k miles.
