my 1990 cali 3 is fitted with a bosch plate rectifier and bosch regulator,is it worth upgrading theses parts and any suggestions.
i replaced the generator ring and the reg/rec. on my cali with parts from eletrex world
Do the originals still work OK, if ‘yes’, leave alone. On my last Tonti bike I put on an electronic regulator, intended for BMW boxers, ‘because’, aka surely it has to be better - not because the original was faulty, which it wasn’t.
I would say if it is working then leave it alone, unless you want to run more equipment on the bike such as heated jacket etc. The standard system is old technology, but is generally pretty reliable so long as the connections are good and clean.
