The wires are for a throttle position sensor (TPS). Lectrons are purely mechanical and do not operate using a TPS system. Simply disconnect it, wrap the end up to prevent dirt from getting in, and secure it out of the way. On some models, you can disconnect it from the harness completely.
All fuel lines have air in them. The difference is you can see it in the transparent line now.
Lectrons do not require a specific oil mixture. Mix it according to the oil manufacturer’s recommendation.
Yes and no. Lectrons come with a good base tune from the factory, however, every bike tunes in slightly differently, and each rider has their own personal preference. You may need to adjust it accordingly. Once set, it will compensate for most elevation, temperature, and humidity changes. Changes in engine and fuels may also require adjustments.
Yes. While the Lectron can compensate for elevation, temperature, etc., it cannot compensate for increased load on the engine. Lectron recommends richening the power jet at least ¾ of a turn, and the metering rod at least half a turn. Different engines will require different adjustments. A spare, richer metering rod in a 2nd slide (P/N 2021) is an easy drop-in tune up for dunes/snowbiking trips.
Lean out your metering rod ½ turn to gain more idle adjustment. It is too rich.
You may need to clean your needle seat valve.
