Well...I suppose you could call it that, but by definition, an air pump cannot cavitate. Now you may be getting an air bubble in that fuel line, but that seems really unlikely and defies simple physics. Unless, of course, there is a restriction like a second (or third, depending on what we

A thought: When reinstalling the petcock after cleaning the tank/tube filter, it's critical to keep the mesh filter as straight as possible as you fit it into the tank. This means holding the petcock body securely with one hand and oriented to its final position as you tighten the retaining

Check your petcock screen. That should be the only filter if your bike is still stock. If you are handy enough, look at the free to download honda factory service manuals and clean out the jets in carbs. On Thu, May 9, 2019, 9:08 PM Harold Peters wrote: > Before the filter I was able to get it

My apologies I meant second fuel filter. And what I believe my problem right now is cavitation. The bike in my picture is a 1984 650. Got a blue 1985 being torn down on my back porch. Right Zippy engine but need rear brakes and seals as well as a left bottom side plate that seems to have a leak.

The easiest way to check the gas cap vent is to just pop open the gas cap and go for a ride (be careful of spills/splashes and maybe not try this with a full tank.) The vent is there to allow air to enter the tank as it empties to keep the pressure equalized, if it gets clogged the vacuum builds

Very nice! If your petcock filter (tube screen) is intact and in good order, tank is clean, you shouldn't need an inline filter. Any more filtering restricts fuel flow. They didn't come with one from factory On Mon, May 6, 2019, 8:37 PM Amanda Wurzer wrote: > This was yesterday > > On Mon, May
