Ok, I got sick of waiting for my 04/550 starter motor, so I managed to find out that the Mitsuba SM-14( fitted as std) has a spline that is fairly common. So I bought one on Ebay(US) for $20us.I got it the other day, and had to make a bracket to fit it, as the mounting end and holes are different. I used my old s/motor mounting end and the remainder was from the CBR600 f4 purchased on ebay. The newish s/motor has a bigger armature and is aprox 9mm longer.
Having fitted it and getting very excited about how much money I saved and how clever I had been, the Berg wont start off the button? Bugger!
I cant work it out. It still kicks ok. So today I spent the day following the "hard starting guide". I am unsure of a few things, firstly the resistance between the yellow and blue wires, does " <1.0 ohms" this mean the reading should be LESS than 1 ohm or GREATER than 1 ohm??
I measured 0.4 ohms? All the other values seem to be ok , but with the following exception, "Coil charge wires ( red/ black) Volts AC, when the bike is "kicked" (loaded and unloaded) I get 55 VAC, compared to 31 VAC when electrically operated??????????????????? So does this mean (A) the engine doesnt turn over fast enough on the button to create aprox 35VAC, or (B) is the s/motor drawing to much away from the stator, or (C) is 0.4 of an ohm not enough resistance and my stator is stuffed?????
I have tried to contact Mitsuba to ask how the s/motors are rated, but it is a Japanese site and they have not answered 5 requests? By the look of the s.motor I would have thought it would more than do the job? And would this have happened if I had bought the 04 s/motor which is also a larger unit???????????????????????????? Like I said I am stuffed!
Could it be the "auto decomp", I have actually pulled the manual decomp, lever in a little as I turn the motor over(as this worked with the old s/motor, before it burnt out) but it still wont go.
ps, I also have two batteries fitted!
Please help, if you can.
Thanks,
