Fuel Filter

Hello...
I wanted to know if someone tried to install a fuel filter to the Versys...
The OEM teabag is garbage.

it is what it is...

Think you are meaning something like an external fuel filter like bmw bikes use:
Thought about it when had my bm but safety concern plus it needed a long fuel pressure hose.



I think bike manufacturers won't like as a standard as a fuel pressure leak could cause a fire. Cheers!

In my country for example, when you travel to the provinces, bad fuel quality is very common so I think an external fuel filter may help to retain all those particles that could clog the injectors. The only thing possible to do (I believe) is to cut that short fuel hose in the middle and insert an small but efficient fuel filter... maybe something like this; http://www.motorcycle-superstore.com...T.ac=SLIsearch

it is what it is...

Here they put about 10l of water in 100l of petrol. (Greedy thieves)
It's impure fuel full of particles to begin with. (Government monopoly)

This subject has been mentioned before, but I don't remember if anyone tried to implement a filter 'inside' the hose.

It´s a matter of check if there´s enough room for the filter in that space just below the gas tank... we don´t have monopoly here but you don´t know if some gas stations add water or anything else. Out if the city sometimes I smell the fumes of the trucks and let me tell you.. that not smell like regular diesel!

it is what it is...

It's fuel injected . . .it should already have one.

Kurt, remembered reading this type of filter.

Doesn't really tell the quality but at least will prevent dirt and water from getting into the petrol tank.

Fuel Pressure (High Pressure Line)
With Engine Idling: 294 kPa (3.0 kgf/cm², 43 psi) with fuel pump running.
Fuel Pump Type: In-tank friction pump.
Discharge: 60 mL or more for 3 seconds.

Most inline fuel filters have a 40 micron filter element... You could get a Golan Super Mini (left) 10 micron fuel filter:



"After success with our first fuel filter, we at GS Performance made a decision to manufacture new fuel filters for the High Performance Motorcycle and Go Kart Industries, and today we have the best billet, stainless steel, washable, reusable and performance fuel filters in those two industries.
Filter Element: Designed and engineered for the aerospace industry, for rugged, high temperatures, and extreme filtration environments, made of pleated, 304 stainless steel, 10 micron (.000392"), 1.000” Diameter. Totaling four square inches of effective filtration area, mini/super mini filter provides a maximum flow of 6 gallons per minute simultaneously with no restriction. Filter elements are washable and reusable indefinitely, cleaned easily with air or soluble rinse.
Bodies: Machined on CNC from 6061 aluminum, chrome plated or clear bright anodize finish."

Great filter for a gravity feed bike, I don't think they will take the pressure.

As long as you are not putting rocks in your fuel tank, most fuel is probably not going to clog the injectors. Filter or not, water will still pass through the system unless you have a fuel/water separator installed. Water should not hurt injectors, but enough of it could prevent combustion and even hydrolock your bike in great quantities. Diesels usually have fuel water separators on them because it's rather hard to remove water from their cylinders (remove the head or injectors). Gas vehicles do not, because it's relatively easy (remove plugs and turn over). The Versys, like many other bikes, has throttle body injection, which is basically just a slight step up the technology curve from carburetors.

It just squirts fuel into the throttle body and it mixes with air, as the natural vacuum effect of the engine sucks it all in. It should actually be a pretty decent sized hole on the business end of the injector, bigger than most particulate you'll find in fuel.

I believe that the majority of failures on fuel injected vehicles are fuel pump failures, which are generally due to the clogging of the fuel filters. Whether it's an in-tank sock or an external bulb, usually when you replace a non working fuel pump in a car, there's a nasty fuel filter at one end of it. Either it's not getting enough cooling because a dirty sock is restricting flow, or the pump is overheating because it's trying to push fuel through a filter that's clogged and giving too much resistance.

Here's the problem as stated before: the Versys has almost no room under the tank. The Versys also has a very expensive pressurized hose that is short to prevent the fuel line from going lower than the injectors for some reason. You have to get a filter that would be large enough to provide the flow needed by the Versys when its using the most fuel, otherwise your performance suffers, and the engine could even die at higher speeds.

I'm all for engineering (read: rigging) things up, my bike has lots of zip ties and farkles. However, I would probably focus on finding suitable replacements for the in-tank filter. If you're dicking around with the fuel system on this bike, you gotta take the fairing and tank off anyways, it's just as much trouble to get an aftermarket replacement [read: a sock not specific for this bike] for the in-tank filter sock than it is to mess with external filters. Especially since you need to shield the fuel pump from debris just as much as the injectors. You would just need to be replacing two filters instead of one, to protect parts (injectors) that I've rarely seen fail in 'ANY' vehicle (not just the Versys), and possibly accelerating the decline in a part (fuel pump) that I've seen fail in 'EVERY' vehicle.

I don't think I've seen clogged injectors on here. (btw you can usually fix that with good injector cleaner). But I do I think there have even been Versys fuel pump failure posts on here (which you can usually fix with a new 200$ pump). I could be wrong though.

This is just might two cents. I'm not personally attacking anyone or anyone's idea. If you put an external filter on your Versys, please post pictures and the results. I would just giving my opinion, because I have experience with throttle body injected vehicles and fueling issues in vehicles in general. Do not take my negativity towards the mod as a negatively towards innovation or modifying the Versys. It's your bike!
