RE: SPE 40cc
Used Motul 800T synth with BP Ultimate fuel with a 32:1 (150ml to 5lt)
I was lucky enough to get advise from the guy who designed the SPE40 and he recommended synth oil for the break in.
I sure hope it becomes easy to start as it hasn't been that yet. Again I am hoping the Dynatron will solve my starting probs as I do have a weak wrist/arm from a bike accident.
