Hello folks,
Excuse my ignorance but after searching around on the forum for abit I couldn’t find any information about taking the starter motor apart.
I remember years ago coming across a guide for it but no such luck.
Much appreciated if anyone could send me in the right direction
Thanms

I know of the same guide, think the pictures are long gone.
I've done it before, and it was a giraffe, as you have to get all 4 carbon brushes past the commutator.
You can use toothpicks or thin crocodile clips to hold them back on reassembly, but it's very difficult still.
Word to the wise, when I did mine it never worked properly afterwards, had to buy another one

Not a problem, thanks for the reply Banner.
Did you get a new motor from somewhere or was it 2nd hand?
Obv Kwak don’t do them anymore (along with original coil packs, hence my other posts about changing to stick coils but I think stick coils will fry the Igniter due to their secondary resistance and feeding a pulse back into the igniter)

2nd hand one from ebay.
I was trying to sort out my starting issues, and thought it might be the motor...turns out that new battery leads and a much higher cranking battery (175cca!) fixed it...

Ah yes I happen to own a set of you’re much improved battery leads.
Maybe a higher cranking battery will help as well

Is the YT12A-BS a straight swap banner or did you need to lift the battery up to reach the cables etc?

Straight swap, it's the same dimensions as the oem, and the terminals are in the same place
