Dual carb set ups - ?

eight six.

For the TPS setup you will have to get creative. If the bike carbs already have a TPS on it, remove it and check the spindle drive shape......you might have to machine an adaptor to fit the toyota TPS. Then you will have to fabricate a TPS claming/attatching method.....its best to clamp rather than bolt solid as it allows you to run alot more adjustment.

To setup the TPS you need to have your TPS on the throttle body, measure the resistance at fully closed, and the resistance at fully open. This is done by using a multimeter set ot ohms and bridge the 5v and signal wires. Just mvoe the throttle and you will see the resistance change. You MUST match the stock tps resistance settings for idle and WOT (wide open throttle) or the map will be wrong.

To run the MAP sensor you need to tap the top of the manifold runner behind the butterfly (to prevent fuel dropping into the vacuum lines). Then you need to feed all the lines to a vacuum manifold with one takeoff on one side for the TPS, and one takeoff on the other side for the brake servo.

courtesy of Ian bergins photobucket lol.....i sent him the bits for the vacuum manifold. You can see how the manifold is tapped and the vacuum manifold arranged.






To set the MAP you dont need to, it runs off atmo pressure differential so no calibration is needed.

And for standalone igntion system, try KMS....but you will need a crank trigger setup, TPS info (you can use the bikes one and just scale it), a coil and the ability to map.
