hi I understand that the condenser can get too hot .can it be moved and if so how and to where?many thanks.

Common practice on Montesa's is to disconnect the stock unit in the backing plate. Purchase any good automotive condenser and mount and ground it between the frame reinforcements in the headstock. Splice the condenser wire to the hot wire from the coil. No more heat failures or pitted points. 

What do class as the hot wire from the coil thanks again.

It's written in spanish, but I hope the pics are clear. I use modern electronic condensers that cost around 0,5 euros.
