[/color]i use a 75 micron pancake style. next year i'm gonna try a 150 micron. my medium is screen/mesh
placement right in between the carbs for max flow. i've heard having sitting it to high at an angle or laying on it's side can cause fuel starvation when tank gets low. any inputs on this thread would help all in the community.and its prob one of the most important things that can be overlooked :eek:

I need to be educated on this fuel filter issue. Since the 500r apparently does not come stock with fuel filter, why is it necessary, or desirable to have one? Does it protect the carbs, jets, etc.? If this is the case, why don't the manufacturers provide?

there is one on the inside of your tank on the backside of your petcock.
ha! Yeah right! Fuel FILTER?! NO WAY would i call what's on the petcock a filter. more of a screen. It sucks HAAAAARD core.

the reason you want a fuel FILTER is because that screen lets all kinds of crap into your carburetors. The EX has been known to have carburetor fuel flow problems caused by debris that got by the screen and lodged in the (quite) small pilot jets, debris that would normally be caught by a fuel filter. Many of the engine related problems you'll find here are because of a clogged pilot jet. You're gonna have crap in the fuel tank, it's a given. reduce the chance of malfunction (and lost road time and money for repairs) by installing a $5 fuel filter. If not for you, then for the person who buys your ex when you trade in. for me, it's reassuring to see that the previous owner took the time to make sure that problems are prevented, rather than seeing a pile of repair bills for the same problem... donno about you.

A fuel filter is one of my winter projects this year. Bike already has close to 30k on it, but I figure I may as well go ahead and do it after I give the insides a thorough cleaning this winter. I figure the Ninja will be in 50 different pieces by December.

What about taking those screens off of the petcock and just running an inline fuel filter. Those screens look too small to do anything serious.

The best are going to be brass filter media, but any Small Engine fuel filter will do. I bought mine from Fleet Farm as a Briggs and Stratton Fuel Filter. It was (crap, was it red or white? i think white), flat disk type. cost me 5 bucks or so. never had flow problems. where to mount them? I mounted mine between the carburetors. fit really nice. How? Cut your fuel line install spring type hose clamps (not regular band and worm hose clamps), install filter minding flow direction, camp it down, and you're done. Remove the tank for better viewing and install.

If i still had my EX, i'd put up a how to this weekend. however at best MS Paint is the best i can do. I'll spare you my artistic suicide.

That seems to be a common one used.

From another site, these are the instructions I've gathered - feel free to correct me if I'm wrong.

1. http://diycycle.info/index.php/topic,44.0.htmlRemove the gas tank.
2. Cut the fuel hose.
3. The filter will indicate which way is In, and which is Out. Gas from the tank flows in, and gas flows Out to the Carbs.
4. Use clamps to squeeze the fuel hose onto the filter, and voila.





Looks something like that.

Credit to diycycle.com for a bit of info there. Does that help?

Mine is a pancake style B&S filter like you recommend but there was no indication of flow direction. Can you elucidate?

On the bronze one the flow if through the bronze from the outside to the inside. So that you can see the dirt accumulate.

Thanks fellas. I'm going to look at a different fuel filter over the winter. The one I have has no flow direction requirement but it has starved my engine for fuel a couple of times since the cold weather hit.

I've had this problem since I bought my bike in July. The guy I bought it from installed a HUGE filter that caused the line to pinch. The pinched line is all fixed, but I still need to buy a new filter and install it.

I stopped by my local multi-brand motorcycle shop asking about the fuel filters. The guy behind the counter said my 2005 should already have a fuel filter on it (besides the screen in the tank I presume, but failed to ask). Can any newer-model owners or worker-on-ers verify this?

How often would these small bronze filters need to be changed? My car filter guys say every 30k miles & my car gets about 32 mpg, but car filters are pressurized and have way more surface area. So... ?

Your bike comes with a bit of mesh over the inlet tube inside the tank. This is not the same as the inline filter between petcock and carbs that is being discussed.
