Fuel filter or not

[polkaudio]

I was running a bronze fuel filter up to last season when I smoked a piston.

 

After finishing the top end, took it out to break in and it ran absolutely terrible. Acted as if it was going to seize up.

 

So we're pulling things apart when my buddy suggests checking the flow. We pull the line off of the T and it's barely flowing.

We pull the filter out and fuel is running fine. So we think maybe it's clogged and put on a new filter. Well it flows as bad as

the old filter.

 

So my question. Is there a better filter to run? I know there's a screen at the petcock, but I still want to run a filter to keep sand out.

 

And was this filter the culprit of why I broke a piston in the first place. I've heard the bronze filters can cause a lean condition.

Is this true?

i have heard of a few people that had problems with the filters restricting the fuel flow on bigger motors. I personaly do not run one and see no need to.

I used to run a filter when i had stock carbs without a problem. When I went to bigger carbs it seemed as if the bowls were running dry. Ditched the fuel filter and never had a problem after that. If you are seeing a flow difference when the fuel filter is inline I would take it out, and just rely on the screen the petcock has. Been running mine in the sand that way for a long time with no issues.

 

As far as the lean condition causing your bike to blow up before. Can't say yes or no. If you were running the bowls dry its very possible the cylinder wasn't getting enough fuel, and as we all know the fuel is what lubes everything.

try this is you still want some filtered gas.

i got em on two fuel jugs and have been great. they filter out all the crap at the bottom of the fuel jugs so it wont enter your gas tank.

loos like a mini version of the fuel filter on my 06 Dodge Diesel

When I recently installed my pingle I noticed a lot of really fine crud partially plugging my stock petcock screen. I had previously removed the two inline filters right in front of my 34mm carbs to get better flow. After the pingle install w/no inline filters, turning on the petcock with completely dry carb bowls, I could hear it sucking air through the gas cap vent tube for the first time, and it filled the carbs very noticeably faster and left no bubbles in the line like before.

 

I would recommend cleaning the stock petcock screen and running no inline filters. If that doesn't improve it enough get a pingle.

Thanks everyone.

 

I'm going to get the Cascade filters for the cans.

 

For the Pingle, is there a specific model for Banshees?

you can also try drilling out the gas cap on your tank too. on some of the billet after market caps the hole is kinda small. drill it out and it should help vent a little better

Nice find ed...thank you.

 

I still use the stock fuel valve on my drag bike, removed both screens...but use a screened funnel when filling up.

My fuel always comes from a sealed drum...so a little less exposure to the elements...
