The way I figure this is if you get anything in the carb, you have lost the battle and must pull the carbs.

If that little filter on the petcocks is the only thing to filter out krud, then you better keep it fresh.

Nothing is going to get through that paper filter, and you can see exactly what if anything it traps. No longer have this single point failure available to you.

The inline filter is cheap and since most are clear you can actually see if there is gas flowing.

You don't even need clamps becuase there is just no pressure.

And as mentioned, get the ones for a lawnmower and there will be no flow issues.

I agree. You'd be surprised how much stuff gets past the fuel tap mesh and even the filters underneath the float valves. And you'd be surprised how much crap you can get in fresh fuel.

My old 750EF used to flood one carb every few months because it got gunk under the float valve. It had the tap filter and I'd flushed the tank, but still this happened (honestly cant remember of it had the float valve screens as well).

After about 5 times of taking the carbs off I put a paper element in-line filter on it and it never happened again.

The key is to get a good quality filter because the cheap Chinese ones can sometimes impede fuel flow.
 
I don't know... I was running the clear lawnmower filter when I got the bike, but was having flow problems so I ditched it. I don't have a rusty tank and don't run a filter other than the what is in the petcock. No problems for years now.

You obviously must shop in the $0.50 clearance items bin.

Depends on luck, really. You can try to only fill up at busy filling stations where it's likely that the fuel is fresh and untainted and they have some standards.
Otoh, even at that, you could end up with just the one fill that contains a lot of stirred-up muck from the (filling station) tank bottom, because a careless employee didn't allow the tank to settle before putting it back on line. You never know how the filling station's own filters are doing, either - strictly speaking, they should be working all the time, but obviously they don't - again, slipping standards, carelessness, etc.

The major drawback with the small filters in the carb bodies, is that once they get choked, it's a major pita to get them out and clean them. Having been the victim of abovementioned careless employee(s) before, I've been fitting in-line fuel filters for decades and find it's easy to keep an eye on them. If they start off yellow and turn brown, I know they've been doing their job, and saving me a lot of roadside hassle, or having to be recovered by trailer, etc.

Anyway - the way I look at it is this - if the Army / Navy / Airforce all think it's worthwhile to filter their fuel, I am of the same opinion. Offhand, I can't think of a single military vehicle I've encountered in my (admittedly limited) experience, whether it rolls, floats, or flies, that doesn't have damned good fuel filtration on it.

Makes perfect sense;I'm glad I did not have try and prove it mathematically.:)

Of course they do. When the gloves are off, the last thing you can't count on is quality fuel.

Your suggestion as to brand is? And it was on the bike when I got it.

I used a Ryco filter (not sure if you get them in USA) which was pretty much top of the line in Oz. It was a car type filter as well, so it had a greater surface area of paper compared to a smaller filter. Had on on my 1150 as well and never had flow problems.
