Mike, Thanks for your info. I was actually asking for my Dad and you were very helpful. He said it is running rich until it gets warmed up and then it seems to run ok. If you have any other suggestions we would appreciate them. Thanks again, Sissy
As the retired Starfighter weapons electrical genius suggested, clean the EFI contacts and componants. A 16oz can of SeaFoam(1/2 can per tankful)will clean the injectors and valves. A new set of plugs and a clean breather element will work wonders :wink: Oh Yeah, Mr.Folks was all over those F-105 Starfighters when Luke Skywalker was a glint his daddy,s eye :wink:
Steel is right, the F-105 was the Thunderchief,F-104 was the starfighter.
When I was in the USAF from 1966-1974 I worked on several fighter-bombers and interceptors. Some were the standard relay operated systems with associated wiring. One was Pneumatically operated, electrically controlled(F-106 Delta Dart) a real "&#@$%# to trouble shoot at 3 A.M. for an air leak.
Dave posts it on the web so I don't think putting it here is a problem BUT Please don't waste the man's time . Read the site , buy a DVD from him , read some more , then and only then bother him . Dave is just a decent guy that we're constantly afraid of burning out .
Mr. Copcicle - I agree that Ewing is really helpful guy, and we should not bother him unnecessarily. So I will ask you and anyone else on this forum who may be able to help me. My ZN1300 motor runs pretty well, but based on the smell, it seems to be rich under all throttle conditions, idle to full throttle. I plan to install a broad band O2 sensor. Assuming we can confirm that it is flowing fuel to the return, it has been suggested that an adjustable regulator would allow us to dial down the pressure slightly and thereby lean the mixture. Have you ever heard of anyone doing this on a ZN1300??? This is common practice on automotive injection systems.
In case you have not seen the Stiletto, it is shown in some detail on pages 5 and 6 here:
I live in Carnation, Wash. The Stiletto was on display at the Seattle Motorcycle show last December. I have replaced the plastic cam chain idler, installed a later type self adjusting tensioner, and the engine has a total of about 20k miles, 175 pounds compression on all cylinders.
