Fuel filter kit just before injector

Got 'em! Had to ask for them and they were behind the counter so that one could never find them on one's own, but I got 'em nonetheless.

OK, so you cut the old clamp, pull the hose, shove the filter up the hose, use the new clamp, and that's it? No need for the Swiss army knife?

Except for the small step that the filter goes, small end first, into the plastic body of the fuel rail.
*THEN* the fuel hose is put back on like normal.

Like so:

Oh boy, this looks really involved. Looks like you have to remove the side covers, the tank and the subframe just to slide a fuel screen into the fuel line. Has anybody done this, and would you like to write up a how-to???

Instructions are already provide in this thread - along with photos.

But I have read several threads in other forums about poor results with this filter. The CanAm filter seems to have a much higher success ratio.

I removed the CanAm and installed the KTM filter a few weeks ago. After about 3 or 4 hours my bike started running poorly. I think my injector is partially clogged. It may have gotten some dirt while I was working on it.

Today I pulled the hose off and couldn't find the filter - at first. It was down inside the hose rather than in the fuel rate inlet. I don't know if it wiggled out while riding, or if it just came out when I pulled the hose. It looked like it had a fine film covering it, but it is so small it was hard to tell if it was plugged.

I left it out and reinstalled the CanAm filter.

Instructions for installing the filter once you get to the injector spout are here, yes, but that's not what I was asking about. I was asking about how to get to the injector, as I asked about tank removal, etc.

On my Buell and other street bikes I've owned, the tanks have all come off with one screw. This Husaberg is my first dirt bike, and I could use some coaching. Please.

Sorry, I misunderstood your question.

Removing the tank is a bit of a pain. There are instructions in the manual, and I believe there are step by step photos in the thread on checking the valves. But here is a short version...

1) Remove the seat

2) Remove the shrouds

3) Remove the seat brace (don't know the official term). 6 large torxs bolts.

4) If you have a fan installed: You have a choice. Either remove the two bolts holding the right side radiator so it can swing forward out of the way. Or remove the the silencer and the 3 subframe bolts so the subframe can drop out of the way.

5) Remove the air filter and cover the intake port.

6) Disconnect the fuel pump wiring connector.

7) Disconnect the fuel line quick disconnect and cover each end with the caps to prevent dirt from entering the system.

8 ) Lift the tank and pull it off the air intake boot. This step is kind of difficult.

9) Once you get it part way out, disconnect the low fuel wire on the back of the tank.

You now have the tank off. Reinstall it in reverse order, but connect the quick disconnect before you fully seat the tank (while it is on top of the air boot) so you have room to get your hands in there.

Once the tank if off, you can see the fuel line and where it attaches to the fuel rail.

I hope that helps.

Thanks! That's very helpful, and I appreciate it.

One item to add to DeeG's very complete steps.

8 ) Lift the tank and pull it off the air intake boot. This step is kind of difficult.

If you spray (or apply with a paper towel) a little silcone spray around the edge of the air box boot ... and the gas tank area where the air box sits .... it makes things slippy/slidy .... and a WHOLE lot easier to get on and off.

Just to be sure to throuroughly wipe it off before re-installing your air filter.

Good luck! E-Ticket

All this just to install a fuel filter, and the whole process has to be repeated every time the fuel filter is serviced.

I'm not going to do it. The filter can stay in its box.

I'm going to hold off on putting mine in also. In a thread at KTMTalk, someone mentioned that they were taking them out of the Husabergs at ISDE. Don't understand why they'd do this, unless there was a known issue?

Anyway, I'm due for a valve check pretty soon, so I'll decide then if it goes in or not...

If anyone hears anything further about the suitability of the KTM filter in the Husabergs, please post it. It would be really interesting to know why they're pulling the filters out of the race bikes at ISDE.

Maybe contact spongebob1 over at ktmtalk. Here is the thread: http://ktmtalk.com/index.php?showtopic=431715

Here is where I first heard suspicions about the inline filter...

http://www.thumpertalk.com/forum/showth ... ine+filter

When I pulled mine, after only 5 or 6 ride hours, it looked slimy. I don't know if it was plugged up or not, but it looked suspicious. My bike was running lean and hot, but I am not yet sure what the problem is. I have a replacement injector on order. When it arrives I will inspect the injector to see if that was plugged.

To be safe I removed the KTM inline filter and installed the much larger CanAm filter.

What's the poop on the CanAm filter, please?

Why is nobody replacing the original filter inside the tank ? That would seem logical to me

I suspect some like having a filter after the point of disconnect from the tank so it catches any dirt that might get in the line when you remove the tank.

Here's a couple of pictures I took of the filter replacement..
It shows a trim tool I used to remove the old filter.
The dirty filter shown has only 1,000kms from new !

The reason can be that the filter swells when it gets warm and restricts the fuel. If the filter is a little dirty in addition it can affect the performance. http://www.husaberg.org/forum/viewtopic.php?f=7&t=15226#p127534

hey imagine if someone owned one of these bergs and really didn't know what the injector was or where it is on the bike, how would you go about telling that person??? only a friend of mine has asked me in confidence and i don't know how to answer it without someone getting embarrassed :wink: :wink:

Thanks for this useful thread. Got the filters and wash kit given to me by my dealer and planning on fitting filter soon. Checked the links to thumper talk etc and saw comments about this being more prevalant in the UK. Only thing I could think of here is supermarket fuel.
Fact - I got a letter from my car lease company with instructions not to buy fuel from a specific UK chain
Hear say - Apparently supermarkets buy fuel at or close to refinery change over from diesel to petrol and vica versa as the price is much lower. There must be a reason; probably quality and higher risk of contaminants?.
