mixing tires

[Rick McCauley]

What about fuel filters? I don't like the small ones made for for motorcycles. I put one on my Suzuki GS1100E. Shortly after, I decide to get on it hard. after a couple redline shifts the bike started cutting out, so I backed off the throttle. As long as I rode normally it ran fine. When I got home my nice shiney new header had turned a lovely shade of blue. A sure sign of lean fuel mixture. I blame the restricted flow of fuel, that only has gravity to get it through the filter, and to the carbs. I know the KLR is only feeding one carb, but I don't want to starve it. I figured the only way to get good filtering, and good flow was to use the largest inline filter I could find. Any thoughts, or better ideas. Rick A17

Make sure the diaphragm cover is tight. I would also check the o-ring that seals the selector valve to the petcock and the o-ring that seals the petcock to the fuel tank. If fuel is not shutting off that could be for several reasons. The o-ring seal on the diaphragm plunger may be bad or missing. The selector valve seal could be also bad. I see this problem more than a bad diaphragm. The selector valve seal can be reversed so that you have good sealing surfaces again. The petcock repair kit includes all these seals, o-rings and diaphragm. One problem I have seen is that the rubber bits from the selector valve seal will sometimes end up in the float valve and cause it to not shut off. This will create a very rich condition and hard starting. If your KLR ever acts like the choke is on when it isn't, I'd clean the float valve and then check your petcock selector valve seal.

Could be that it washes down stream to the float bowl...just not my experience.. .therefore, probably not. smile. = In all my experience of diaphragm failures, it must pee gas on the engine (and the next act, sets your bike on fire!) cough. Since Fred sells the diaphragm repair kit--maybe he could comment on failure types. My started with a mysterious fuel stain, unknown source, then eventually, a full fledged leak that I could see happen. A word of caution on that fuel filter--you may be going to 'reserve' sooner than before the installation. It would be worth watching, perhaps deliberately checking the mileage. With my fuel filter, (two types) reserve came a full 50 miles early,@~4 gallons used and reserve was only good for about 8-10 miles. Of course, there is the double secret reserve of laying the bike on the left side and sloshing gas into the left half--good for another 8 miles. Ah, double secret reserve--nice to know, painful to use. YMMV (and reserve may very as well.) revmaaatin.

That makes sense. If I recall correctly, the sintered-metal filters have a higher flow rate than the paper filters, so they're better for our gravity-feed systems. I don't use fuel filters in my gravity-feed bikes, but I make sure the fuel petcock strainers are in good shape. The bikes with electric fuel pumps just get an ordinary paper filter.
