Its a very easy but useful test to make sure your spark plug is ok , you may need to clean the electrode to ensure you get a good reading but all you then have to do is set meter to read ohms and measure from the spark plug cap end to the electrode tip , and then from end to body to make sure no leakage to earth.

Get set up turn meter to ohms reading on dial and clean the electrode as below 

Test between end of spark plug where HT lead cap fits and the tip of electrode the reading is very low only 1.2 ohms 

on a dirty part of electrode the reading goes wild and eventually read 188.9 ohms so very bad and to avoid this clean electrode tip 

Next test from spark plug cap end to the body to make sure no earth leakage your meter should read OL which is a good reading as it signals no leakage to earth via the body.

See video of this process below

First ill show a quick test on diodes inside you regulator rectifier .

You are just checking current flow through the regulators diodes in forward and reverse bias.

connect + lead of multimeter to further left connector pin 

and common lead to 2nd pin from left you should get a voltage reading of around 0.6 

here i get 0.52 which is ok

then test 3rd pin from left it should give same reading 

now connect common lead of multimeter to left pin and + lead 

of meter to the second pin from left you should get OL telling you no 

current is flowing as it should be.

Now test with + lead of meter to third pin from left and same OL

no current flow 

 

now connect common lead to the further right hand side 

and + lead to second from left you should see 0.6v i get 0.52 which is ok 

move red + lead to thurd pin from left and should get 0.6v again i get 0.506 which is ok

Switch + lead to further right pin and touch blue to second and 

third pins and you should get 0L no current flowing

Cagiva Mito 125 Evo: Touch-Up Paint & DIY Color Repair Guide

A few stone chips shouldn't ruin the look of your Cagiva Mito 125. Because original Italian panels are becoming harder to source, maintaining your existing fairings with high-quality touch-up paint is the best way to preserve your bike's value and aesthetic.

This guide covers the best kits for the classic Cagiva Red and Cagiva Yellow Evo models, along with tips for a professional finish.

What’s in a Quality Touch-Up Kit?

A professional-grade kit should include two stages:

1. Solvent Basecoat: This provides the actual color pigment (e.g., Rosso 501 or Giallo 473.201).

2. Clear Coat (Lacquer): A nitro-synthetic clear coat to provide the glossy shine and protect the paint from fuel spills and UV fading.

Popular Cagiva Mito Touch-Up Links:

• Yellow Cagiva Mito Paint: Perfect for the bright "Agip" yellow Evo fairings.

• Red Cagiva Mito Paint: The classic racing red found on the majority of Mito models.

Pro Tips for Application:

• Clean the Surface: Use a wax and grease remover or rubbing alcohol before applying paint.

• Build in Layers: Don't try to fill a deep chip in one go. Apply thin layers of color, allowing them to dry for 15 minutes in between, until the chip is level with the rest of the paint.

• Flattening: For a truly invisible repair, use 2000-grit wet & dry sandpaper once fully cured, followed by a high-quality polishing compound.

Cagiva Mito starter motor post

Cagiva mito 125 for sale here on Ebay UK

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 .
