thanks a lot for the offer.
I checked the pump and all the cables and connections, cleaned them and sprayed the connectors with WD 40. The contacts in the pump are quite down, I cleaned them with a little screwdriver and tried with a battery, the pump worked, but only a short while. I installed it in the bike, same there. It does pump but I can not hear any reaction when switching on and off with the kill switch.
I connected it with 2 wires directly tro the battery and everytime and I take the wire off and on it pumps. Should it work like that?
At least I could not start the engine.
So I tried to clean the carbs but could not manage to get all the screws out to open the 2 lids on the lower side of the carbs.
That is the situation right now, will try again.
