Suzuki GW250 Inazuma Rectifier/Regulator upgrade....AKA Shindengen Shenanigans!

A wee project I decided to do to "future proof" the Inazuma electrical system....Replace the 1960's tech with a Shindengen "Mosfet" spec FH027AA I sourced second hand from "Motomine"... There will be more videos to come as I need to make up the cables for this and if I go ahead it will involve cutting into the 3 stator wires that leave the stator and splicing in the new ones. This will happen ONLY when I have researched the best way to do this as it could be joining(what may be only) 2mm sq existing wires into 4mm sq upgraded ones that lead to the connectors for the new R/R... Using 4mm sq wiring (optimum size for connector grommets) brings it's own set of problems as finding crimpers that do that size SPECIFICALLY is hard, most generic crimpers seem for house wiring of 1.5/2.5/6mm sq... The problem is the 2.5mm would be adequate but does not seal adequately into the grommets of the R/R connectors. 6mm is a damn tight fit and makes joining 6mm to 2mm even worse!!! I found "US PRO 6736 ratcheting crimpers for non insulated wires" on ScAmazon... hope they will be suitable or I'll be bodging it with pliers lol.....
