Fits all North American 1500cc Honda Valkyrie, 1997-2003 GL1500C, CD, CT, CF
In North America, the Keihin pilot screw head is D shaped, making it hard to turn without shelling out some bucks.
This tool is for pilot screws in good condition. If your pilot screws are corroded from salt spray, this tool may not be strong enough. Pilot screws in good condition turn at 0.5 in.lb and bottom out at maybe 1.0 in.lb. The Stubby tool will round out at 5 in.lb. of torque. Corroded pilot screws can require more than this to get them moving. Red Eye offers another tool, called Hella Stubby, which has a stainless steel bit. Hella Stubby will withstand much higher torque and costs more than this tool.
This tool is made of a thick brass tube and brass handle. The tool fits into the pilot screw hole, and sits on top of the vacuum cap or vacuum line as in the picture. You need to lift up as you turn the tool, to keep the business end engaged with the pilot screw. The handle has 4 sides, so you can count faces with your fingers as you turn it.
Why would I need this?
When I first got my Valkyrie Interstate, it was second hand. It ran a little funny. I made a tool like this one, except with a fat round handle and only an inch long. It took hours to make the tool, and the result was obnoxious. The slick round handle on my first tool was difficult to hold onto and turn because my fingers kept getting greasy. Counting turns was an ordeal because my fingers were always blocking my view.
The square handle on the stubby pilot screw tool really helps, so you can count turns without seeing. The handle clears all hardware in the area, so you don't have to loosen the intake clamp or pull the vacuum line or vacuum cap.
I discovered my pilot screws were all set at 1.25 turns out from bottom. Everybody said to set them at 2.25 turns, so I did. It ran a lot better.
