Ok, so we are making good progress on the Bandit resotration. (Pics will be up soon)
We cleaned up a rusty tank with KBC Coatings & I'd like to add a fuel filter as some insurance to keep crap out of the carbs.
Someone here mentioned that some fuel filters can cause rough running due to the fuel only being gravity fed.
Anyone have any advice on what to run for a fuel filter? I know some of you are running an inline filter. Does it work alright?
Thanks!

I just installed a Russell filter. Aluminum body, scintered bronze cleanable filter element, about $20. Looks like the same technology as the Pingel for about half the price. I haven't run it for long, but I don't seem to be having any issues with it so far. An added benefit to using the cleanable screw-apart filters is that if you suspect a flow problem, you can just screw it apart and remove the filter element.

where do you get these from?
-
Yeah i had one which really didn't flow enough. Bike kept dyeing when being used at WOT for over 30 seconds completely baffling until i removed the element from it and found it worked fine.
-
I had the same problem. It would die at high revs after the fuel level dropped too low. I think the best advice is to coat the tank and then keep it clean.
Mine was made for cars, has a nice glass body so you can visually inspect it, a pretty good sized plastic, cleanable element, but it just didn't flow enough. I pulled the filter element out of it, but left the filter body in place. Because of the way the fuel flows, it does act as a sediment trap, so that's a help.

i run pingel, dont use the clear little cheap plastic ones. On a side note these bikes act funny with when the fuel gets low so much so that i raised my tank up in the front. This goes for the b4 and the gk73a
-
They only get funny when fuel is low if you have a fuel filter restricting the flow i think.
-
driill a bigger vent hole
-
don't add one, just keep the tank clean and full at all times. Talk to ather bike owner, they know where the clean fuel is in your town. There's only a couple of places here that I will full up at unless I reaaly need to
-
there is one under the gas cap also the over flow tube on the bottom of the tank is one that some times rust inside the tank and and gets crimped off

where do you get these from?
I got the filter from my local independent bike shop, they were in the Motovan catalog, I do't know if that's just a Canadian supplier, maybe it doesn't help you.
Jay, you mention how your bike acts funny when the fuel is low. Before I installed the filter, with a bog stock bike, when my fuel level started getting low, but way before reserve should have been needed, the bike would lose power and start acting like it needed reserve, when I switched to reserve, the problem went away. I assumed the petcock was getting tired, and I'm planning on replacing it, but I believe you have said you run a Pingle petcock, so are you saying you still have this problem with a pingel, or have I misunderstood you?

No i dont have the fuel flow problem with the pingle what i do have a problem with is i need fuel cell foam in my tank to take up the sloshing and this may also aid in the other problem that once my fuel gets so low when im on a long right handed carousel i have fuel issues because of the placement if the fuel tap ideally two would be good like old bsa's or triumphs

Motovan is a Canadian only supplier. What makes you think that you should not have been close to going on reserve?? Does is not make logical sense that if switching the bike to reserve and the problem goes away YOUR LOW ON FUEL !!!!!!! Obviously you don't know the inner workings of a fuel pick up, Petcocks DON'T get tired!! Not in that way anyways. They are simply 2 pipes of different heights in the bottom of the fuel tank and a valve that switches between the 2. When the bike start to run out of gas on the higher of the 2 pipe you switch it over the the lower of the 2 pipes and proceed on your way. With a 400 I would find a gas station soon as you have about 3.8 l of fuel left. On a stock Bandit you can run anywhere between 160 to 240km before hitting reserve and this all depends on the kind of riding your doing

They do have fuel flow issues. I took Jay's advice and put a good Pingel filter on my bike. Then took out the whole petcock and cut the plastic tubes/filters down to little nubs. Any crap in the tank is picked up by the Pingel filter and can be cleaned out after every track session.
I don't have a fuel delivery problem any longer.

The issues your talking about can be contributed to the fine plastic mesh on the petcock tubes getting plugged up. Nothing a good old fashioned scrubbing with an old tooth brush doesnt cure. In fact when I worked at a bike shop during summer holiday many many years ago that use to be part of a spring tune up, clean out the petcock so there were no fuel flow issues.

Jay, thanks for the reply, that's what I needed to know. :thanks:
Gary, thanks for the info, interesting to know, but since I'm a street rider, not a racer like you, I don't want to lose reserve functionality. :beers:

First of all, THANK YOU for pointing out what I obviously don't know. Your attitude is extremely helpful.
Since the petcock is simply 2 pipes of different heights in the bottom of the fuel tank and a valve that switches between the 2, the vacuum line that goes to the petcock is obviously a figment of my imagination, and it is impossible that the amount of fuel pressure above the petcock influences how fully the aging, possibly stiffening diaphragm opens as the head pressure of the fuel decreases.
I need to switch to reserve when I have about a half tank of fuel left. This is what makes me think I'm not "LOW ON FUEL !!!!!!!"

Just cut the plastic tubes off and get a good fuel filter solves a lot of problems :stickpoke:

If the diaphram was too stiff to open the on/off valve fully it would also be cracked. Then you would be flooding cyl 1 !!!! But you already knew that cause your soooo smart
-
I know where to get a diaphragm kit for the fuel valve.
-
You know where to get a fuelcock rebuild kit?
-
I dont know everything but yes i do know where to find one
-
Actually posted it on here once
-
Lol and where may this be?
-
Some where in here have to look and see what bike had the vacume and same gasket

this looks close but cant be sure it was that year

Is this what you were using? Our fuel line is 3/8", right"?

I want to run a fuel filter. I had an "issue" this weekend. The cyl 2 float stuck and filled the cylinder with gas. I think its cause there was some left over junk in it. I cleaned it out and it it was fine after. Good thing I checked the cylinder though as it was completely full of gas. What a pain to get it all out..

5/16th.
I've gone to a paper auto-sized disposable filter instead of the replaceable kind because I think the media works a bit better. That and the larger size acts as a surge tank for additional fuel, the theory works well with the Pingel petcock. I still see a little silt here and there but nowhere near as much as when I was using one of those clear replaceable element ones from "da boys".
Ironically, I got a float stuck in #2 not too long ago and it did the same: flooded out a cylinder. Worst was that I had just changed the oil not 20 min prior. I think it was some debris that had slipped past the hose because I had the supply line off earlier.
I think this winter I'm going to strip the failed Kreem and redo the tank entirely. A total PIA but has to be done.

How bad does it dilute the oil? I should probably change the oil again now. Damn...
-
Look at the oil level, if it's higher than what it was before, change the oil. It depends on how long it sat for after it filled the cylinder.
What will happen is that the fuel will wash the cylinder walls clean and slip past the rings and dilute the oil in the crankcase. You risk spinning bearings etc since the oil has been broken down.
I just went and changed it again because it's cheaper to buy oil versus cracking open the cases and replacing bearings. Didn't do the filter, just the oil.
-
I thought the fuel hose was 5/8's. But I've been wrong before.
-
You may be right Mike.
-
5/8" is a fire hose :annoy: lmao the proper size is 8mm or 5/16" :beers:
-
Thanks for clearing that up! LOL. I knew it was 5 something... Duh. 5/8 is over 1/2 inch
