1977 KZ650b electrical problem

I little to late to help now, but just for info, nothing needs to be unsoldered, the wires pull out through the bars. It may not look possible, but what goes up must come down as the old saying goes, Kawasaki originally pulled the wiring through the bars. This can be done with connectors and all still in place. I've done it myself on a KZ650 so anyone don't believe it, you're wrong. If you unsoldered all those wires, unless you're an expert at soldering, you'll need all new switchgear as it's ruined.

Yeah, after unsoldering my father pointed out all you need to is remove the gas tank to get to the wire harness. Easily unplugged from there. I screwed up pretty good. Oh well, live and learn

Odd question but, do you know if Honda/Suzuki switches will fit on this particular Kawasaki? Are the electricals interchangeable between these manufactures?

I apologize for all the questions folks, this is my first "project" bike. I've owned a 750 honda shadow and a 900 kawasaki vulcan, and I can already tell -this- is going to be the most fun bike. None of the previous were any work.

Hi Sad gruffman, Does all the wires go through the handle bars on a '77? If so the later models have external wiring and connect in the head light housing. Saves a lot of time and headaches. Bob

The wiring goes through the handlebars (or did, until I pulled them all out) and feeds behind the headlight down under the gas tank. At the gas tank it is supposed to have a Male/Female end I believe. Seems this one was cut (or maybe that is how all the '77 model b's are) and each individual wire is held to the other wires by very small clear plastic cylinders. (resembling a straw, only thicker)

I don't know which of these might fit 1977 KZ650.
Good Fortune!

Patton is my hero.

I'll be taking that handlebar switches for that 78SR, Looks perfect for 15bucks! I'll post a picture of progress this weekend. (hopefully a picture of some nice beautiful clubmans instead of flipped handlebars)

...shopping around on Ebay for the switches I need, I started noticing the incredibly low handlebar prices that are out there...found an offer of clubmans, bar end mirrors and grips! My bike doesn't have mirrors or grips currently, so this seems like quite the buy...7/8 seems to fit every 70's era motorcycle I've come across.

The 7/8 handlebars should fit just fine.
Good Fortune!

Ordered a left hand switch from a 1979 kz650SR, It should fit a '77. Also ordered the Clubmans, free shipping is epic. Having some trouble finding a decent looking 70's era left hand switch. Anyone have suggestions? Would it be a safe assumption that a 1980's lefty switch will fit just as well as a 1970's?

Per kawasaki.com, left-hand handlebar switch,
Part No. 46091-055, is common to the following 15 models:

KZ1000-A1 (KZ1000) (1977)

Yep, pretty much everything but Hardleys use 7/8" bars. It's a little more difficult to check if they will clear your tank though, even if you are in the same room as the bike. Just about anything can be made to fit though.

oops, didn't realize there was a whole 'nother page here
