Note Z1-R Owners!

If You Own the 1978 Z1R That Has a Separate Rectifier And Regulator, You Can Remove the Connectors From Both And Remove the Regulator And Rectifier Off the Bike. then Take the New Regulator, Plug the White Bullet Plug Into the White/Red Frame Wire From the Harness, then Take the Black Spaded Wire And Ground It To the Frame. Plug the Green Connector Into the Regulator Spot And Reconnect the Battery. That's It. You Will Get About 13 Volts Out Of It. You Won't Get 15 Volts Like the Factory Part But It's Better For the Battery. It Will Require That the Bikes Battery Be Properly Charged Before Installing Though As It Won't Work With a Low Battery.

Works Perfect Installation Sketchy

Posted by Tom Zinninger (TOK) on Dec 23rd 2019

The unit works superbly, holding (in my case) 15.25 volts at any RPM, steady as a rock. The issues I had were 1. An extra jumper wire is included with absolutely no instructions of any kind. Mechanics supposed to have ESP? 2. The unit has a ground wire that terminates in a rounded V for mounting with a bolt. The bike has a female plug joint. Admittedly, both are trivial but if the manufacturer wanted a home run with this thing, a couple of SMALL changes would get it done. Just a bit half a$$ed the way it is.
Qualidade e honestidade

I bought this store for many years, it has a great variety of products, always with quality and always with kindness, education and honesty.
Very nice part

The Voltage regulator look to be a quality unit with a fairly heavy cast aluminum body. The mounting flange surface is thicker than stock so you'll need longer 6mm bolts. My only grip is the two wires that are not attached to the factory style plug are very short. It's a good thing my bike didn't need either one! Time will tell how long it last. Oh yeah, it does indeed put out about 2 volts less than the overpowered stock unit.
