just wondered about using one as I cleaned my carbs last night (one slow jet plugged solid! 
)..I've read good/bad things.
Thoughts on using one?

fuel filters, who runs them?

Heaven is so far away.
Most petcocks have one built in (but each one really is different, so check for yourself). If you do decide to run one, make sure it's for a gravity fed system. Fuel injection type filters depend on pressure to get gas through the filter.
Basically, try one. If you get fuel starvation at higher rpm's take it off.

I do. Mine are clear and I can see the chunks they block. Of course I don't have a stock petcock. When I did have one, I ran one filter for each carb and never had any starvation problems.

Therapy is expensive. Riding is cheap. You decide.
If you let your bike sit for more than a couple weeks without running it, filters will start to deteriorate. That was the issue with mine. After a 10 month rebuild, it was disintegrated, and kept sending pieces of filter into my float needles.

Maybe you should get some filters that aren't made out of bubble gum and leprechaun farts.

I've been running these:
http://www.partsreloaded.com/Snowmobile/Air-Fuel/In-Line-Fuel-Filters/In-Line-Fuel-Filter-Clear-Walbro-Type-OEM-414-1194-0109-579
for 10+ years, and they've been great. Though as Rich says they are not necessary if you have screens on your petcock. I still run them in addition to a screen though. Clogged jets are a lot larger pain in the ass than installing an inline filter.
If your filter is destroyed after that short of time it either wasn't intended for fuel or not the type of fuel you had in it. I've used many inline filters and never had that issue leaving some in 6+ years and never dry.

I have a Harley Sportster that someone put a neat little anodized aluminum filter on between the tank and the S&S shorty carb. It unscrews and there is a fine copper screen in it that you can take out and clean.
On an old Norton I had with a rusty tank the filters saved the carbs for years until finally all the rust was out of the tank simply from use and a few yearly cleanings of the filters. So get some sort of filter that is re-usable that you can take apart and clean periodically if you have a problem with dirt in your tank.
The old brit bikes did come with copper mesh filters that went up into the tank, and the old Amal monobloc had a re-usable filter built right into them too, so they were all set from the factory.
If you dump fuel into your bike from a can, especially one that is not yours, make sure you look at it really good, it could have dirt of water in it that will stop your bike dead.....
Modern bikes with E.F.I will certainly have everything they need in filters engineered right into them from the factory.

I'm running with a new aluminum tank so have little concern about rust. But my petcocks have no screen at all on them, so at the beginning I was running nice chrome and glass filters.
But then one fell and broke on the garage floor. That ended that. Tried a pair of cheap knock-off anodized filters with cleanable screens but they didn't allow enough fuel to flow (even with one per carb). So in the trash they went and I'm now running no filters and having no troubles.
If I have a fuel delivery problem I know my Mikuni's are super easy to clean out if a jet clogs, but one day I'll spring for a pair of high quality black anodized filters and have them again. I don't want the inexpensive clear plastic ones on the XS, although I know they work great.
Come to think of it my BMW doesn't have filters either, but the petcocks do. Mikuni's on it too, and even easier to get at and clean out if need be.

am i the only one who takes the time to run my fuel through 3 coffee filters while wearing gloves in a lab clean environment while robots designed for the task pour the fuel at such a rate and in such a manner that it doesnt collect debris from the filtered air?
man... you guys need to stop abusing your bikes.

while your waiting for the fuel to drip through the filters its a good time to gold coat all the connections on your bike. once youve finished that you might as well do your weekly bike rebuild including full detailing job.
oh, and it doesnt hurt to check transmission wear every other week also. come on, it only takes a few hours to split the cases and put it all back together. 8)
