Change your fuel filters!!!!!!!!!!

[jerryz]

Here in Thailand i have to change the fuel filter every 5k as the local gas is filthy, and clogs up the running making it run lean in the UK i can leave it for 10k at least .

Just changed my fuel filter on the 2000 M900Sie.  It was disgusting.  Bike fuels much more smoothly now!

any special considerations to take into account when swapping out filters?  haven't done one of these before but i imagine it to be fairly straightforward.  guess i should order one up from desmotimes

My bike had been running shitty for like 6 months as I tried everything to diagnose it. Valves, timing belt, throttle body synch, new plugs, you name it.

Note to self:  Always start with the easy, cheap stuff.


I can't count the money I've thrown at bad plugs, bad filters, poor carb adjustment.

Yeah, I should have known better. 
Simplicity.

I usually change 'em out around 12K just because they're cheap and relatively easy to do when performing a 12K service.

My 01' m750 only made it 6500 miles before it gave me fits.  That was several years ago and I remember starting a post very similar to this when I found the problem.  Word to the wise if you use fuel stabil in the winter months while stored it will clog the filter much faster.

For the S2R models (and I think the S4R models  But don't quote me on that) I have put up a topic in the Tutorial area.

Hope this helps some folks out.

thanks much for the tutorial link; looks very helpful... i'm now inspired to order up a filter from DT and replace mine also.

Fuel injected bikes are much more prone to clogging fuel filters, this is due to the higher pressures the system is running at. Years ago the shop that used to work on my 851 did not change filters at the 6k services, I had filters clog up twice. They started doing it every tune and no more issues.

Those older bikes with the crap regulator/rectifiers would blow the rectifier due to the extra load when the fuel pump was trying to force the fuel through a partially clogged filter.

Carb bikes run such low pressures  that often the debris will get caught in the filter, and just sit in the bottom of the filter rather than trying to be forced through with pressure.
You can get away with more with a carby than efi.

I do all of my bikes at every tune, in part due to the fact it is cheap and never hurts. Well as long as you put it together correctly and do not have a fuel leak above that vertical cylinder exhaust pipe.

after speaking to a local NAPA guy in town and asking if they had FIL 3032 in stock, he said they also have FIL 3002, which is basically the same as FIL 3032, except all plastic.  though when i told him this was for a motorcycle application, and the filter was going to be in the tank, he seemed to freak out a bit and tell me A) i needed a smaller filter (3011) and B) it had to be all plastic or risk corrosion in the fuel.  is there any truth to that?  he claimed to have had many motorcycles and never had the filter in the tank and was apprehensive about putting the 3032 in fuel.  am i understanding how all of this works??  i've never done this before so that's a definite possibility.

and i went to autozone yesterday and they were out of NAPA brand filters, but said that they had an equivilant filter, a Luber-finer brand (http://www.luberfiner.com/htdocs/products/fuelfilters.html).  i forgot the p/n for what they ended up selling me, but it looked to be about what i saw installed in the tutorial thread:  http://ducatimonsterforum.org/index.php?topic=17213.0

so my question is should i go ahead and try installing the Luber-finer filter, or make a run to NAPA to get p/n 3032?  or use the plastic 3002?

(the luber-finer filter i bought looks just like the NAPA one in the above link)

Buy the 3032 and ignore the guy at NAPA.  Gasoline is not corrosive.

Yeah what a fooking idiot.

well, right...i think he was thinking along the lines of gasoline has some amount of condensation in it...especially if it sits for periods of time.

that said...i'll try to switch mine out tomorrow; i'm curious to see if it's got much or any crud in the filter...

Fixed.
