Some owners have had issues with blocked injectors, weather this is from bad fuel, tank contamination, or from manufacturing processes its a pain in the ass. If you have a 08 bike with the early injectors take this opportunity to upgrade to later style. on the left is 08 type, the right is the later revised type, different spray pattern and hole layout, but same flow rate.   At first i thought i had a faulty injector as installing the later type solved my problem, however after some time the upgraded injectors have become blocked. Ive had both new and old injectors cleaned in a ultra sonic bath and pressure tested, they were all very bad and alot of crud came out of them. To stop this from happening again i've installed a simple in-line filter, which can easily be replaced. This is the filters http://www.ebay.co.uk/itm/160774996636?ru=http%3A% 2F%2Fwww.ebay.co.uk%3A80%2Fsch%2Fi.html%3F_from%3D R40%26_trksid%3Dp4712.m570.l1313%26_nkw%3D16077499 6636%26_sacat%3DSee-All-Categories%26_fvi%3D1&_rdc =1 All you need to do is remove the seat, using a stanley knife ive removed 50mm of fuel line from here   then push the line over the filter at each end ensuring you have the flow arrow the right way, its a perfect tight fit, but just to be safe i fitted a jubilee clip at each end, ebay item 260331092276  The space is perfect for the filter, there is nothing for it to snag on, i even had enough room to insulate the filter too.    | ||

This is a sample I pumped out of my fuel line once I'd removed my injectors, god knows where it's come from. Look at all the small flecks ! [IMG]http://i66.photobucket.com/albums/h264/avalaugh/1125r%20inline%20fuel%20filter/7f44ef76.jpg[/IMG] When I had my frame off recently for the valve check I shook a whole lot of crap out the frame, I ended up removing the fuel pump as there was rattling coming from inside. I think it's some kind of product from the forming of the tank. (Message edited by Avalaugh on April 20, 2012) (Message edited by Avalaugh on April 20, 2012) | ||

nice!!! do you changed only the injectors?? changed something in the ECM? | ||
| Avalaugh |
No, bike runs fine on either set of injectors, with stock and EBR ECU, this has also been proved on dyno. | ||
| Timebandit |
good idea! what did you use for insulation around the filter? | ||
| Avalaugh |
I install back up generators for a living, it was a small piece of the exhaust lagging. | ||

I think it's a great idea. Although I have never experienced fuel bad enough to clog any of bikes in the past. I'll keep this in mind just in case. Thanks for sharing. | ||

Rogue, I personally don't think it's bad fuel. I really wish I had taken a picture of the stuff that came out my tank when I had it off for painting, there were large chucks of a hard Amber colored plastic type resin, which were shaped to fit into the corners of the tank, these had been floating about for the life of the bike (i pressume) Obviously the large parts were blocked from the fuel filter sock on the pump pick up, but this doesn't filter down to very small microns, hence all the particles in my injectors  IMO all bikes should have a easy access serviceable filter, I'm just going to change it once a year now. The problem is it's a slow gradual process, the injectors don't just suddenly block up, at first the ECM tries to accommodate for them by adding more fuel, it's only when it gets really bad you'll notice. Most bikes don't get ridden much, so again this problem isn't showing much yet, but my guess is as the bikes get older, this resign is going to break off from inside peoples tanks and this blocking process will become morecommon. Fit this filter set up as a precautionary measure so you don't get issues in the future. Hope this helps everyone. | ||

I like this idea but... Gas over here in USA is filtered at the tank farm and at the pump. Would think it's that way around the world. If the gunk is in the tank to start with, you'd think with the ethanol we run over here that it would show up quickly as being a problem. The problem I have with this addition is there are two more potential failure points (the clamps) in the fuel supply. This is a pressurized system, so it's good you decided to clamp it. Maybe not a problem, but I'd be worried about a slipped clamp from the vibration. EDIT: IS THAT FUEL FILTER FLANGED ON BOTH ENDS? (Message edited by two_seasons on April 21, 2012) | ||

How about the pressure on the plastic filter? I like the idea though. | ||
| Avalaugh |
There is no way those clamps will move, without them I had to pull extremely hard to get hose off the filter, with the clamps on it's impossible. I had a spare filter I used to do tests with, the bit of hose I cut off I pushed on the filter, and clamped in my vice, I stretched the filter spouts trying to pull clamped hose off. I also left a bit of this resin in a dish of injector cleaner for a week, it was not effected by it, it's obviously fuel proof, but with the repeated heat cycles and vibrations, I think it's this that's caused it to break loose. | ||

I've used that type of filter in the past. Even without clips, the hose sometimes has to be cut free of the barbs on the filter body. There's no way that will fall off Your Ethanol adulterated fuel in the USA may be an issue for the plastic though. I tried one on a Methanol fuelled bike and the filter melted before my eyes  | ||

Crow, I'm not certain how the UK works with the EU, but I do know that Ethanol is in fuel here in Germany of at least 5% and now 10% is available. So you are probably in the same boat or will be soon enough. I aim for the 5% as my bike likes that. I wish we could get 0%. | ||

Are you sure that the filter is rated for high enough pressure for an injection system? it looks more the type you'd fit to a carburettor system. A steel filter as fitted to the X1 would probably be a safer bet . | ||
| Pariah |
Avalaugh, thanks for the tip about the injectors... nice side by side comparison. Your post has me thinking about using a fuel system cleaner a lot more often. | ||
| Nuts4mc |
Havalaff - Kevmean may have the more correct solution...Zuki Vstrom's (DL1000) have similar issues - only the zuk's Fuel filter is inside the pump - I have modified my Strom with the addition of a NAPA 3023..it's filters down to 13 microns and has a steel housing..be careful with that plastic one overtime heat can cause the plastic to fail... her's a picture of a Magneti Marelli unit fitted by a fellow Strom rider over in the UK...the P/N looks like it ends in "4002" Good luck  | ||

I would never use a plastic filter like that in a fuel injection system were you have high fuel pressure! I like the idea with an extra filter, but you really should change it to a high pressure type! |
