MT-01 starter motor...
DIR By: DLMA23

---------------------------------------------------------
I have an original 2005 SP1 MT-01 since new with over 100K on
it...
To date I have had to replace 3 x starter motors & at nearly
€700 it's becoming an expensive habit...
It's a sealed unit & the same recurring issue every time...the
magnets on the inner housing detach themselves & it's kaput!
Anyone else had these issues or knows where I might get my
collection of MT-01 starter motors refurbished?

I don't know about yours, but mine is definetely not sealed.
Detached magnets doesn't mean that it's kaput. Many times (not
always) they can be glued back on. I did it on mine (and
replaced the brushes) and works like a charm.

Hi, Mines a 2009 MT01 SP. Can anyone tell me what are the tell
tale signs when the starter is on its way out. Mines a lazy turn
over but always has been. Thanks Steve

Lazyness is indeed a sign, but not 100% accurate. The best way
to be sure : take it apart when changing your oil. It takes 5
minutes to get the motor out.

Re this whole issue. Mine is at 72000kms and is a stage 4 and
1800cc. It still runs the original starter.
It also runs a Li battery which spins a little easier.
A standard ecu MT turns over about 1 1/2 times to start and a
stage 2 or 3 about 1 turn.
If your bike has some issue that means you have to keep turning
it over then you have a situation of declining voltage and
increased amp draw. Would this overheat the starter causing the
magnet problem?
As many of you are in the UK and have longish periods of not
riding, could this be a clue.
Maybe always charge the battery before even trying to start it.
Dont spend time trying to get it to turn over and then putting
charger on, you have already given battery and starter a hard
time.

Where did you get that information ? Just curious ...
FYI : I have a stage 2 ECU and have had magnet failure (2 of
them loose). The OEM really used a minimal quantity of glue
(just one small drop per magnet).
