Gonna give a couple of these a shot (rain coming)

 

I would not do that. Gravity feed systems, like the VTR uses, should not have a filter.

 

What's the downside jaimie? Restricted flow? I've added them to dirt bikes and ATVs without noticing any issues

 

I would suspect that at low fuel levels, you might run into a situation where the flow force needed to flow the filter is marginal. Cavitation at low levels can affect the perceived pressure at the filter.

 

Those are the exact same ones I installed. Haven't had a single problem so far in 500+ miles.

I put them inline with each fuel line running to each carb. I think I have a picture somewhere I can post later.

EDIT: In the picture, the fuel lines are disconnected, that's why they are sitting really low. When you first install the filters, you can watch the fuel flow through them and it moves quite quickly.

 

If you have a rusty tank or something and need protection against scale getting into your carbs then I suggest using sintered bronze ones. Those are the little cone shaped parts normally used on motocross bikes. Not sure if they have them in the size you need for the VTR carbs.

If you are just concerned - don't be.

 

This is why I did it, BUT this is just my bike. I took off my tank to hit it with some primer, so I removed most of the fuel and then removed the petcock to get the rest of the fuel out. It was then, and this was after several thousand miles of running the bike like this, that I learned the P.O. removed the in-tank filter that attaches to the petcock. How I never had an issue with my carbs is beyond me.
So, it was order the stock in-tank filter and wait 7-10 days (it was great riding weather), or grab a couple of these filters and see how they do.
Like I mentioned, no problems in 500+ miles, and I like that you can see the fuel and any debris. They have already caught a bunch of crap.
I still have to paint the tank, so I might just order that in-tank filter and install it as well. Not sure if that will be too much restriction though.

 

These are for 3/8" lines. Hoping no trouble at low fuel level as I push the tank as far as I can. Rode it down to 3.2 gallons today and it was AOK. Fingers crossed!

 

I've used the EMGO fuel filters for the old GL1500 carbs for a dozen + years with no issues.

Thanks guys so far so good! The real reason I did this is the left fuel line tore at the pet **** (or is it petcock?) Anyway picked up some line locally but its a tight bend and didn't want to risk trouble and wanted to ride. There. Now everyone knows i accidentally tore a fuel line.

 

Confession is good for the soul. The mistake is now officially experience.

 

I have used fuel filters on my racebikes for a decade now. And on the hawk for maybe four years year round. (under 0*F).

In my experience they prevent way more headaches than they could cause. Pretty sure all autos use filters.

Would like to hear why not to use them as years of field testing suggest otherwise.

 

Hey Joe, Do you leave the factory filter/strainer in the tank?

 

Heck yeah, I am not gonna dig around defeating one system to make another. I want clean fuel to my carbs.

 

Just fueled up. Put 3.622 in the tank. No issues with strainer in the tank and 2 fuel filters

 

FYI, I just installed new jets, and while I was doing this, I noticed that there was fuel leaking from the filters! I found that they had loosened themselves. I retightened them and used a Sharpie to put a couple index marks on both of the filter ends, so I can make sure they aren't loosening again.

For those that have installed these, make sure they are tight.

 

Will check tomorrow, thanks for the heads up!

 

Just had to dig up this thread and I have had no issues with fuel flow or otherwise in several thousand miles. I have A LOT of fun with my bike, and have done many full throttle runs through the gears testing the FIL mod with zero issues. Like I mentioned earlier in this thread, the fuel flows quite fast through the filter.
