Cagiva mito 125 parts for sale here on Ebay UK

Here on Amazon UK is and excellent book on motorcycle electrics

I am 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 re-lube 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 i am 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
                 
                                   
that is 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 on Ebay UK are some brushes i use

and here on Ebay UK are starter motors for sale Used .

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

Buy 7 speed gearbox from here 

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

Usually the 7 speeds are fitted along 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 the 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 .

Cagiva mito 125 motorcycle battery maintenance

Recommended batteries for the Cagiva Mito 125 on Ebay UK  



First i like to test the battery on the bike .


Test at the battery posts and at the battery Positive and negative wire terminals to ensure you have good voltage at both and to ensure clean terminals .

then test again with engine running .

You should over 12v and them close to 14v at 6000 revs .

Battery , make sure its fully charged remove from bike and recharge

dont just guess and whilst doing this clean up the battery terminals 

and the negative and positive wiring terminals.

If you have a voltage meter you can do some basic tests.

When the engine has been off for at least 1-2 hours with ignition key turned off,

100% Charged 12.60 to 12.8v

75% Charged 12.4v

50% Charged 12.1v

25% Charged 11.9v

0% Charged less than 11.8v



I always clean the terminals of a battery on routine Maintenance too , and i always test ground wires for continuity but its best to test earths with a 4 amp test light to ensure adequate current flow .


sorry for photo best i could find but you get the idea test your grounds for minimum 4 amp current flow .

I remove battery and clean the outside , baking power is recommended to neutralise the acid and any spilled acid under the battery to stop corrosion .

Now test battery and top up electrolyte level 

remove all the top caps for each cell 

and check the level indicator on the front of the battery 

all mine were low so had to top them all up .

Use only Deionized water - as the level falls the acid becomes more

powerful so you are adding water to dilute the acid to its correct strength 

so do not add acid .

I would now charge the battery to full capacity i am not going to as i dont have time during this 

post but will later .

After charging or before you can test each individual cell to see if you have a faulty cell 

test between positive and first closest cell 

and then between cells 

You are looking for around 2v per cell to indicate excellent battery id ignore my results as one its not an excellent battery to i just topped up the water levels and there it was totally

flat but you get the idea .

---------------------------------------------------------------------------

Last thing to check is a load test connect the battery back into the bike and whist turning the bike over so on heavy electrical load test the voltage at the battery 

if you read less than 11v you have duff battery 11v and over indicates a good useable battery .

If in doubt just replace the battery , you can buy them quite cheap
