Replaced stock starter motor by 1.4 kWt chinese no-name one. It's wounderful! It must be the first thing to do after buying 2.3 Rocket!
Morning masturbation trying to start engine is over now! Maybe, living in England, you have a special servant to start you Rocket every morning, who wakes up half an hour earlier then you))) But I can't allow this to me and prefer to start it by myself. Now it takes 2 seconds when it's 6-10 degrees celcium.
Great thanks to this forum and to those wounderful people who created this topeak.
