I disassembled my gas cap to reduce friction during key operation. I followed Fred's commentary and photos. I disagree with Fred a bit about some of his comments. I believe the hole in the bottom of the latch assembly is likely a drain for gas which sloshes up into the mechanism. Gas fumes...

This is about one of my cars. The filter is mounted vertically with the threaded end up. On a forum about the car many like to comment about their oil filters just as many do on this forum. They seem to be very concerned about anti-drain valves and their material of construction. I wondered...

If the filter is mounted vertically with the threaded end oriented up is this valve important? I would assume the filter would remain full with no anti-drain back valve. Is the valve trying to stop back flow from all the oil passages on the outlet of the filter? What happens if you drain the...

" 3. Remove the timing cover even for just the valve check. You could turn the wheel with the motor in high gear and rotate the cams, but you won't know EXACTLY where the motor is on TDC without removing the timing cover. I'm still on the fence regarding whether the valve shim gap is...

It should crank if the neutral light is lit. The 2nd low current circuit which passes through the ignition switch has no effect on cranking the engine. All you need to crank the engine is the ignition switch on (instrument panel energized), kill switch flipped to run, neutral light lit, and...

Another verification: You can verify if the starter pushbutton circuit is working OK by monitoring the "engine trouble warning light". The warning light illuminates whenever you press the starter pushbutton if the clutch lever is pulled or the neutral light is lit. If the warning light is lit...

I've had an Audiovox CC during almost all those miles. I use the mirrors and don't do much head twisting. I almost never look back over a shoulder. I use the CC almost all the time. In fact, I wouldn't ride a bike for very long without cruise. I ride for the open air environment. Twisty...

In recent years I've noticed that the range of motion of my head/neck is somewhat limited. I have difficulty bending my head back looking up. Also the left and right movement is stiff and somewhat limited. I've often wondered if leaning forward on the FJR with my neck and head at a forward...

Do these foam sealing gaskets break down on a filter in an older rarely used FJR? I recently looked at an old filter I had removed from my FJR many years ago and noticed that the foam material had begun to disintegrate. I wonder if there are old filters out there in use and the foam has been...

Test each cap on the pointy input of a Mityvac hand vacuum pump. See if the vacuum gauge indicates a leak after a few seconds of vacuum. Mine appear to be somewhat cracked yet they don't leak.

"Something I didn't mention - at cold startup it idles normally (at ~1500 RPM IIRC) without the lope." This may point you toward the answer. The wax motor cold idle system may be introducing small air flow unbalances between the cylinders. If one of the sliding valves on the throttle bodies...

It's not critical to have the piston at exactly TDC when checking the valve clearances. Please remember that the crankshaft turns twice as fast as the camshafts. So, a 10 degree error in rotation away from the TDC mark at the crankshaft will only be a 5 degree error on the camshafts. More...

Gen 1 and 2 are the same except for where the fuel pressure regulator is located. On the Gen 1 the regulator is mounted at the end of the fuel rail with a return hose to the tank. On the Gen 2 the regulator is in the tank at the pump so no return hose is needed. Electrically they are the same...

"The fuel pump only runs when the fuel rail isn't pressurized." False. There is no fuel pressure sensor in the control loop of the fuel pump. At "key on" the pump runs for approximately three seconds and then stops. It restarts when you crank and start the engine. The pump is powered from...

Put the bike up on the centerstand. Kneel down to the floor on the left side of the bike and rotate/jog the rear wheel with your right hand. Ignore the clutch. It's not needed for this experiment. Using your left hand actuate the shift lever as you rotate/jog the rear wheel. Does the lever...

I replaced a leaking seal on my '04 recently. When I inspected the fork tube up close I discovered a tiny rough spot on the shiny tube. When I slid my fingertip across the spot I could feel it quite easily. The seal passed over the spot as the fork moved. I smoothed the roughness with some...

The 800 mm Hg range I mentioned is derived from a Gen 1 service manual. It shows if either of the pressure sensors malfunction the computer automatically uses 760 mm Hg (sea level pressure) in calculating injector fuel output. We know that the sensors are identical and the '06 FJR uses the...

Likely just reads absolute pressure, not differential. Otherwise, why would it have an output above mid-scale when there's no vacuum? On the pre-2006 models there were two identical pressure sensors. One for the atmosphere, one for the intake pressure. Obviously both of those read absolute...

When you abruptly connect two gears, one motionless and the other turning, you're going to have a clunk or bang. When you're idling at 1100 rpm the large 1st gear wheel can be turning as fast as 278 rpm or 4 revs per second. When you're sitting still and you shift from neutral to 1st you're...
