Special Instructions for Twin Tec Ignition Model 1005K

 


General: The model 1005K has exactly the same  features as the 1005 with the following exceptions:

1) Has zero cranking delay and a 30 second timeout before coil shutoff.

2) Starts in single-fire mode when using a single-fire coil. This is a great advantage over dual-fire for kick-starting because if the first kick doesn’t start it, the other cylinder on exhaust stroke does not have the “wasted” spark to ignite the charge and make smoke. This keeps a fresh charge in the other cylinder.

3) When using the PC Link, disregard the cranking delay utility. That feature is disabled on the 1005K and always set at 0. This will work fine on electric start bikes, also. (The cranking delay is designed to prevent kicking back against the starter…our tests have shown that this is not a problem when base timing is set properly.)

 

                Base Timing Considerations: Normally set at TDC or “0” for most stock applications. However, on lower compression motors, better starting may be achieved by advancing base timing 1 or 2 degrees. Care must be taken as advancing too far can kick you over the handlebars. By using the PC link in this application, the overall timing can be set for maximum performance without adjusting the base timing settings.  

            Carburetor Jetting & Air/Fuel Mixture Considerations: Black, sooty spark plugs that don't transfer spark efficiently can be the result of the air/fuel mixture being too rich or the jetting being too large.

If you are unsure about these settings, it might be best to take the bike to a good mechanic who knows how to set the bike up.
