Solid state rectifier to fit  engines using 2 wire or 3 wire alternator.I will provide a drawing showing what each terminal connects too. I post First class on the day of purchase and it is free post.A lot of happy customers on this item at a very low cost. This is the part that will work on this model so beware of lower cost  items listed that are not marked KBPC 35-04.If you buy an unmarked unit, it will probably be a different number when it arrives and not the type i supply which is the classic bike parts suppliers only recommended type for these bikes. If in doubt, ask the seller the number. If you decide to have a slower economy delivery and the wrong part for the sake of saving a few pence on a £3000 plus nice bike, be prepared for the walk home when it fails and the battery goes flat.
I BUILD AND RIDE BRITISH BIKES SINCE 1969. I HAVE HIGH STANDARDS SO WILL NOT OVERCHARGE FOR POST WHICH COST £2 . I DO NOT POST ECONOMY,MY CUSTOMERS GET FIRST CLASS POST FOR QUICKER DELIVERY IN A PADDED ENVELOPE WITH RIGID FOAM PIN PROTECTION. THE RECTIFIERS ARE RoHS CERTIFIED. MY NOVEMBER 2023 BUILD IS IN THE PICTURES HERE.
THESE ARE THE BEST RECTIFIERS YOU CAN BUY FOR MOTORCYCLE USE. NOT THE UNMARKED ONES OFFERED WHICH ARE OFTEN MORE USEFUL PROPPING UP A WONKY LEG ON THE WORKBENCH.
