Cagiva Mito starter motor post

Here is and excellent book on motorcycle electrics buy it read

it and learn !!

Im going to collect info here on Refurbing starter motors for the Cagiva mito 125

I was hoping to do a full rebuild on this on but all it took was a bit of oil on the bearings and a good clean out and relube where needed .

But its quite easy to change the brushes and bearing on these stater motors and can save a lot of money .

Getting in is easy just three PH1 screws

here you see the brushes holder plate i cannot find these to but if anyone know let me
know and ill link to it .  i use sizes 5mm wide 8mm high 15mm long 

here im undoing the Brushes spring clip 

one you undo the main positive side brushes you can remove plate 

here are the positive side brushes the current  goes thought the connector on side of 
starter then through the field windings and then into the armature via the brushes 
then out again via the opposite side brushes 

the negative side brushes are  on the plate
and although it would be easy to change plate fiding them are hard 
i usually ......

Cut the old one off at spade connector then grind connector flat 
clean surfaces and re-solder the new brushes to this connector 
i did not have to do it this time but i will in the future .  

To change the Positive side brushes you will need to remove armature and winding
undo all the securing screws

remove drive gear retaining clip and gear 

                                         armature will come out and then you can access the brushes
                                      connector you need to clean and flux and then solder in new brushes
                                                 DONT FORGET THE INSULATION
thats all i have now ill update this when i do a full stater motor refurb and solder in new brushes
but have a go its quite easy .

Here are some brushes i use

and here are starter motors for sale Used .

Cagiva mito 125 7 speed gearbox 5P engine Gears ( difference )

Buy Bitcoins

I get asked a lot about the differences between the 7 speed and 6 speed bikes .

Usually the 7 speeds are fitted alonmg with better barrels carbs and exhausts so yeah there is a big difference , i have tried and ordinary 6 speed with a 7 speed and yes it was also fun .

Im not the sort to obsess about power and gear ratios etc but yes 7 speeds are fun but then again so are 6 speeds .

Here is how you tell if you engine is 6 or 7 speed and the mechanical differences .

As you can see in above picture ( not very clearly )  the engine code stamp 5P this tells me it is the 
7 speed engine .

under this stamp is the engine number 

Mine begins with BG97   which tells me its a 1997 model so a cagiva mito evo 1 1997 .

That s how you tell year and if its 7 speed from the outside of engine .

Here are the internal differences 

The engine cases are thje same as in a six speed Cagiva just shave off a bit of metal to be able to squeeze in the extra gear .

close up picture of machined casing 

The only other differences are in the gearbox itself obviously 7 gears on input - output shafts 

Cagiva also added an extra selector fork which is needed to select the gear , i presume the shafts are the same lengths as before to avoids case changes and i also assume the selector drum would be different ill find out when i get a 6 speed in bits to compare .
