TOPIC:

about a year ago i seen a item on e-bay that was a conversion for a kz650 to make the regulator and rectifier one unit. mine is a 77 and i'm either over or under charging all the time. i think it was about $90. without changing the entire harness any ideas how to make 2 units into 1 ? both parts are to expensive and outdated to contuine trying to solve this problum. i have a new stator($450 thank you local dealer!)i just can't figure this points in the regulator thing. is there a bolt in/wire in solution to my no charging problums?

sorry about the delay on the thread.HAVE FAITH AND YES THERE IS A beast out there that will replace both the regulator and rectifier.I instaled one on my 77kz650b1 last year and it was only around $100 from dennis kirk the part # is 20-1268 for a b-1 and 20-1248 for c-2.It is easy to install and you can use the OEM wiring

thank you very much! i'll go order one right now!

Also Tony Weeks over at Oregon Motorcycle Parts makes the solid state replacements for your rectifier and regulator. I just ordered a new rectifier from him for my '75 KZ400 and it works great. Plus a good warranty on it too.
