I got a 1972 Honda CB125 about two weeks ago.
She ran fine but i was out for a drive when she backfired a few times and stoped dead, now i have issues starting her up.
I am totally new to bikes and mechanics so if something that i say does not make sense then please let me know and ill try to elaborate.
I have spent some time in this forum and on youtube so this is what i base my findings on, not experience.
i believe this to be an issue with battery/charging as i we have had the spark plug out and it gives a nice healthy spark (although she might be running rich) and the carb has been cleaned.
The only way i am able to start her is by push start.
Once the engine has run for a bit i can turn it off and she kick starts first kick no problem.
Left over night and she wont start again.
I have battery power as the speedo light comes on.
I wanted to check the wiring and once i took the seat off i realized that this could be bad.
the wiring is awful.
I wanted to check the stator and the rectifier/regulator but i did not have time to check both.
the rectifier/regulator is only connected by two wires (yellow and Pink) not 3 (green is not connected and there is nothing lose to connect to)?? i dont know if this is the issue or if the bike could be wired to not need that 3 circuit??
When i checked the rectifier the unused wire showed higher resistance than the other 500 ish for the used and 720 for the unused. I dont know if this is normal because of the 3 not ever having current trough it or that the unit needs replacing as i understand they should all show the same figure.
My second dilemma is now if i wanted to check the stator, which i have seen how its done, i only have 2 wires not 3 in the loom (the black and white you can see connected to yellow and pink)?
A side from the above do you think that my starting issues are due to battery/charging if the only way i can start it properly is by push start.
Thanks for the looking
