Why not try to look for a miniture toggle or push switch which has both NO and NC function at the same time. From Telemecanique, Allen-Bradley, Honeywell or OMRON Brand Name. If your going to use a relay, you will still need a switch to energize/de-energized your relay for its switching operation.:idea: i have an idea, how bout if the pink cable try to connect with relay where's that relay use 3 connector or 2switch that can be choose with no and nc which the nc will be connect to gear2 and no will connect to gear4 and the center of the switch will be connect with the ping wire cdi.
and as the result by automatically the booster RPM at gear 2 will be use in gear 4 also
is there anyone knows what is the maximum RPM at gear2? :shock:
