Timbo, that original 907IE Hitachi starting relay is just same unit, what Ducati have used to these day in near every modell since 907 AND its CHEAP from Ducati dealer. I really cant remeber, how much, but so cheap, that i bought one for spare, if need that part quickly in middle of driving season, so buy that original Hitachi realay, thats my advice. I am electrician and i have heard, that its very realible starting relay :thumbup: Nothing, like that Lucas shitty part in 750, where i have changed ALSO that Hitachi unit. :laugh: Not anymore problems since in my 750 starting circuit. I have also made bigger 16square mm wires to both bikes starting main cables, what is also important, that any voltage drop happen in those cables!
...."Antti do you still ride in the stuff up there ?".... Did U mean my Ducatis? If so, next summer: saturdays 907IE(if good weather!!!), sundays 750 Paso(if good weather!!!), ST4S, another days, (no matter, what weather...) HAHAHAHAHAHAH...... I have fixed my both Pasos to so good condititons, that they are now ready to my museum and this newer ST4S is for daily use.... :funny: But anyway, that ST4S is horrible bike to maintain compared to Pasos

There is TOO MUCH allkind stuff inside ST4S frame and no space at all... better take engine away, when check valve adjustments! BUT 117 hp with Ducati Ecu and 128hp with FIM 59 ECU, what is 46 hp MORE, than in "not tuned" 907IE :funny: :funny: :funny: My 907IE:s engine is tuned many ways, but not yet dynoed...maybe this next summer ill check, how much she have... :thumbup:
