I'm hoping to get the starter motor opened up today to get a proper look, I'm still very new to bikes though, this being my first bike and I've been doing all the work on it myself, with my brothers help.
It was narrowed down to the starter motor and brushes, as the wiring is all good, starter clutch was recently repaired, new battery and the starter relay is working fine.
I'm now researching opening it up and how to clean it so I don't muck it up today lol
From what I've seen while looking for brushes is that they are discontinued, hence trying to find ones compatible. But I'll have a look and see if I can bring some life back into my current ones with Hairsy's advice!
