fuel filter

I'm planning on installing a large IMS fuel tank on my klr and since I'll have the petcock off and putting it on the new tank, I'm wondering if I should remove the filter inside the petcock and just use an in- line filter on the fuel line. It would be easier to unclog or replace should gunk get in the gas (I understand there is quite a bit of plastic debris in the IMS tank that needs to be rinsed out) but then again, I don't really know what I am doing much of the time. Any thoughts? Thanks.

Matt, There is a kid of filter in your tank, but it will allow the passage of particles that are too large. I run one in between the petcock and the carb. The type to use is currently up to debate. For me only, I am currently running the disk type, but I plan to go to the glass type with replaceable filters. As for the seat, take off the plastic side covers. Look directly below where you butt would be, or your passengers legs. You will see one bolt on either side that requires a 10 mm socket to remove. As for your battery, try filling it with replacement acid, and distilled water, put it on a battery tender. I use an Optimate battery tender and it has a line of LED lights of different colors to indicate my batteries current condition. If your battery is completely depleted and you have corroded plates, the replace it. Some have gone to a couple different brands of no maintenance batteries. Personally, I am skeptical about these for one reason. Yuasa had made a self contained no maintenance battery, yet they pulled this battery from production. Considering Yuasa batteries have been around for almost eternity, I think I'll wait until the marketplace is totally happy with the results of their product.

Always something interesting from the Professor. So that way you check the float height without taking the carb of the bike, neat. And you common sense compensate for the not quite vertical angle of the carb. Do I understand this ? Bogdan

To add a fuel filter or not to add a fuel filter? Reasons for and against requested. THANK YOU. KEN MADISON>WI

The obvious reason to add one is to keep dirt out of your carb and engine. The only down side is the $5 cost, the five minute install, and the aditional point of failure over a straight fuel line. This assumes you buy a good one that isn't going to hinder fuel flow. I'm using a 90 degree sintered bronze filter that I got from Fred at arrowhead motorsports.

That reply covered it exactly right. There is not much more to say other then then fact that this should be a "must do" item since rust in the gas tank is pretty common for these guys. The stock filter inside the tank may just be enough, but people have also found those to fall off now and then leaving you with no filtration if you don't add the inline filter. Oh, another upside to this is that you can visually confirm that you have gas flowing from the tank if you have an inline. -- Doug Herr doug@...

UPSIDES: 1. Generally, keeps all crap out of carb. 2. Even keeps out chunks from petcock gaskets. 3. Easy to check if using clear plastic bodied filter. 4. Cheap and easy to replace. 5. Spares readily available, or easy to pack a spare. DOWNSIDES: 1. Increases fuel line resisitance and may cause you to switch to reserve much earlier and/or to effectively run out of gas, even though the tank still has plenty. Gravity feed may not over come the resistance. 2. Fuel filter increses risk of vapor lock, as filter body absorbs heat, heats fuel to vapor state, fuel flow into carb stops. This has happed twice to me, both times in high-speed runs at ambient daytime temperatures of 110-115 dF. 3. Not effective as a water trap. I still use them, just gotta be sensitive to some flow issues. I also keep a 6-in section of straight-through fuel line in the tankbag -ready to go, just in case I get really pissed off. hth, MarkB

'tis better to be pissed off than pissed on, right? are the plastic bodied fuel filters as prone to vapor lock as brass or metal bodied filters? See you on the 26th? Buddy from the enlightened KLR of Harry Seifert bseifert71@...

I got a little clear filter (shiny copper filter element inside) from the local kawi dealer. It says "Plastisonics Inc." on it for those with bionic eyes. I just pulled the stock gas line from the petcock, attached it (without cutting) to the filter and connected the filter to the petcock with about 1.5 inches of new fuel line. 8000 miles without a lick of trouble (no dirt or sediment is visible in the filter). This configuration lowers the fuel line to the carb so it runs behind the starter motor and a little farther away from the hot engine. Some folks in Moab had to wrap their fuel lines in layers of foil because the extreme heat was causing their engines to cut out. I didn't experience this problem. Why on earth wouldn't you fork out 3 bucks to save a loss of performance, potential breakdown and subsequent carb overhaul? Chicks dig em too - the "lawnmower sounding" klr looks more like it could cut grass with the fancy filter. Kevin A17

If you install a clear fuel filter, this will be step one for figuring out why it won't start. You can easily verify that the vacuum has opened the fuel cock & fuel is flowing to the carburetor. The only draw back is occansionaly having to change the filter but of course, this only because it is working & doing its job. --- In DSN_klr650@yahoogroups.com, "kenbarmore" wrote:
