This is probably old news, but I bought the JEGS filter and am installing it today. However, it appears that the airbox is in the way when attempting to install between the quick disconnect and the throttle bodies. What am I missing here?

Also, how do the pre and post filters remove? I have the pump out but don't want to just start pulling, and actually I don't see the pre-filter.

Thanks.

Hmmm we don't have the airbox anymore... :?
Lots of peeps here changed to the motohooligan or cpr rotty filter setup.

Pre filter is on the top part of the pump, that part comes off when you CAREFULLY open the tabs a bit with a screw driver.
I believe there is a how to on the forum somewhere use the search feature.

Thanks. I figured it out. I pryed the fuel line from it's retainer on the bottom of the stock airbox which allowed the Jegs filter to be connected and live somewhat outboard, between the airbox and the frame. Also removed the course filter and cleaned, but it is still brown, unlike the nice new white ones. Anyone find a reasonably priced replacement for this? The o-ring that seals the pump to the tank is also shot, so I'll be searching the hydraulic rebuilding businesses today as I'd prefer not to give ktm $45.00 for the o-ring kit.

Putting the all assembly back in the tank is a bit of a pain, I'm normally very careful but I damaged the O-ring too despite having some lube on it.
I have a O-ring kit and I put one of those in, hasn't leaked since (5 months) , so I can confirm any o-ring that fits and is oil resistant will work. Screw $45 bucks!

Any updates from guys who did this mode and gone through some serious miles by now?

Anywhere to buy it with normal p&p costs to Israel perhaps?

i'll be damned :)

sorry to "bug in" but we have being running a similar setup in Italy for many km now

we use a totally different approach, for us, ADV, SM and SD so far, the in-line fuel filter must be BIG :)

I work only with big automotive fuel system, maximum 8 microns rated, optimal 5 microns

the bigger the filter, even if the screen is better, the more volume of petrol will be at the injectors when needed

for now we use 4 different filters with same output

BOSCH, GM, MAZDA and ASHIKA

the ashika was recently mounted on a 2008 SD with an incredibly simple and efficient way

Image

Image

picture is wrong, the filter has to flipped up-side down :) but was just to show position

due to it's uge size and the fuel cap 0 micron perfiltering, it will never need changing again, it serves only for safety and water separation (should it ever be needed)

the teabag, original ktm II generation, was simply regenerated with injector cleaner and fresh petrol mixture, 4 washing, and gentle blowing with air

Image

I knw at least 10 bieks running such a set-up, mine has 20.000km plus on che clock, friend of mine, 45.000km, rest a mixture between 15.000 and 30.000 km they ALL go like rockets, most of them have problem keeping the front tyre on the tarmac ahahahaha :mrgreen: :mrgreen: :mrgreen: :mrgreen:

it is one of the best modification youn can do to an LC8 engine, it's funny paper shite is not up to the task

:mrgreen: :mrgreen: :mrgreen: :mrgreen: :mrgreen: :mrgreen: :mrgreen:

Do 40 micron filter (Jegs Aeroflow...) work or should it be 10 micron? (if I'm running it with out second pump filter)

any inline filter that has a rating of 5 microns is what u r after your injectors are small not like a car

Any reason why everyone has mounted their inline filters between the quick disconnect and the TB, and not between the fuel pump and quick disconnect?

My reasoning is purely aesthetic, so if there's something I'm missing feel free to call me an idiot :D

ITS to close to the frame ,and à pane in the ass to reach it then

Did mine today after issues on full throttle, a moment no power and f1 light comes one than its gone again ?

Clean filters forr 2 times now . So let's hope it's gone whit this mod.......(got the torques inline filter )

Just resurrecting this old thread. Is there a reason why it has lapsed?
Is there now a better way to get shot of the troublesome paper filter?

Replaced my paper filter with an inline filter like many before me.
Bike started holding back on acceleration, replaced the paper filter and the problem was gone.

There is a good alternative to the oem filter, at a way better price, if you want to keep the original in-tank setup,

That's what I've just ordered. Are you saying it didn't work for you?

Also, when you were using the inline filter had you removed the in tank paper filter?

The filter is rated at a through put of 900l per hour, it's surely not possible that it was restricting the flow enough to make the engine starved of fuel.

That flow rate is enough to empty the tank in a one minute!

I removed the paper filter from the fuel pump and put that filter I posted earlier in line between the fuel pump and the throttle bodies.
Problems were solved, no more bogging down on full throttle.
