What a SYMPHONY your bike is able to produce! Just MAGNIFICENT! Having the Z 1000 engine as the source and the Vance & Hines exaust as the voicebox, it's impossible not to have that kind of result... You are fortunate for the bikes and for the chance to work on them. May God keep you and your whole family, safe. Sixty four year old Brazilian motorcyclist, riding since 1972 and proud owner of a 1984 ZX9A Gpz 900 R. LET THE GOOD TIMES ROLL!
I feel the same way. I've owned the bike since 1992, but I was afraid to work on it myself. Now days it's hard to find anyone who will work on older carburated bikes so if I want my bike to run or if I want performance enhancements I better figure it out and that's what I did. It's very rewarding to disassemble an engine and put it back together and make it run even better. Ride on my friend.
@@KZRevival For sure, it is a big pleasure to work and adjust the whole machine and after that go to the open road, just the way you do and feel the results of working hard on the bike. Also for realizing that you are getting day by day, more knowledge. Even speaking different languages, we are 100% able to understand each other. Beeing motorcyclists and working on the bikes, does the magic! Be well my new friend!
@@KZRevival yes it’s hard thing. I’ve got a 1996 RF 900 in the carbs got rebuilt by a mechanic that did not run well and cost a fortune Now I found a shop in New Zealand where I live that has mechanics sympathetic to old bikes in fact one of the shop guys has got two RF!
@malcolmwhite6588 Yes, I don't have any mechanics that will do the work either. That was the kick in the pants I needed to try and do the work myself. I wish I had done this decades ago. I enjoy the process, and I give the bike the care it deserves.
@ good on you - yes I do some stuff myself but I’m really lucky to have some mechanics who while they are modern day. Technicians either are very skilled at working on old bikes or they have their own old bikes and work on them and are happy to do so for mine and a good price and with great workmanship.
That's what I'm saying. Everything you listed all equals a connection with the road and some rider skill. There is no traction control or anti-lock brakes, plus it looks and sounds pretty cool.
Looks and sounds superb. Had a '77 diamond sky blue KZ1000 took good care of it, but rode it hard. Went up against Kawi 750 triples, XS Elevens , GS 1000's at Fremont Dragstrip. Reeled them all in. Ran an 11.85 at 109. Kerker and jetting only. Pretty fast for back then. Ride a Z900 among others now, but had just as much fun back then without all the tech. Good times.
Thank you man. This bike certainly isn't as fast as a modern bike, but it definitely gets more attention. The sound of a souped-up KZ still gives me goosebumps. My 2 sons have more modern bikes, and they are nice to ride, but I like the connection you get with the older bikes. Either way, the KZ is a fun bike to ride.
My uncle had that bike in brown when I was about 15. We rode off road together on our 2-strokes and thought his KX500 was nuts. He let me rip thar thing for my first streetbike experience. OMG I can never forget the feeling of that rush because here almost 30yrs later I'm still chasing it. Better than any drug in the world. And this is the high I chose to keep me clean off of drugs and alcohol for 20yrs. Awesome 👌
That's a pretty cool story. My interest in motorcycles was also influenced by my uncles when I was young. More speeding around then my mom should know about. I was hooked.
Thanks for checking it out. I bought this bike in 1992 when it was 14 years. There were faster bikes by that time, but when I saw a hotrodded out KZ, that got me excited, and I had to have one.
I appreciate that, thank you. I don't know about you, but I really enjoyed the whole restoration process. I get a huge amount of pride from the end result. I hope yours turns out exactly the way you want it to.
@@Me-myself-b3g yep both cost you money both fun to ride both can breakdown without warning at the most random times and sometimes you come home and your mates riding it!😂🙈
Beautiful bike, I picked up a '79 kz650c for $300.00. An older guy had it sitting in the garage for 35 years. Its in pretty good shape with 10,371 miles.
That sounds like a fantastic find. I wish I could run across a couple of deals like that. A carb rebuild and a couple of squirts of oil in the cylinders, and it may just fire up. Good luck with your project. Thanks for checking out my bike.

Nice! Rebuilding the rear brake on my 77. Replaced the rear master with a modern one and now rebuilding the caliper. Hope to get it back on the road soon as it's the beginning of the riding season here in Phoenix.
If all you have left to do is rebuild a caliper, then you'll be on the road in no time. These old KZ's sure do get a lot of attention. Thanks for checking out my bike. I'm interested in what type of modern master cylinder you were able to fit on your bike.
@@KZRevival I bought a kit off of Webike. "PMC(Performance Motorcycle Creative) Rear Master Kit With 1/2 inch master cylinder made by NISSIN Compatible with stock brake pedal. Item 75-502." A bit spendy but it's a bolt-on replacement. Once the side cover is in place, you can't tell it's there. This kit appears periodically on other sites like Z1 Enterprises or Johnny's Kawasaki but they sell out fast.
That's funny. I have some high lift cams in this thing, and I didn't really get into the powerband. At 6K RPM and above, this bike wants to pull your arms out of their socket. Thanks for checking it out.
Real nice bike love the old Kawasaki, I had a75 Z1 900 super fast i had kerker header on mine because of oil filter clearance.the vance and hines i see they changed the way they routed it ,back then had to take header off for oil change. and i had a 1977 Kawasaki LTD sold it a few years ago you cant hurt them motors roller bearings on the crank. Your bike is beautiful wish i had it
Thanks a lot man. I used to get these Vance and Hines headers for around $400. Now, they don't make them anymore. In the early 90s, I used to run Star Pro Series headers, and the pipes were routed the same as the Vance and Hines, with a slightly different sound. I like the look of the sidewinder on a stretched KZ.
I had a bunch of these bikes all set up much like this one, low bars and a black Kerker pipe. I liked the Superbike style but it was not a great handler. At 9/10ths it was very good, but at 10/10ths it would try to kill you--so I just stayed at 9/10ths and all was well. in the 80s you could buy these for very little, fix em up and sell for $500 profit, some more, some less--I did it for years! Loved em!
This bike is certainly not comfortable for very long. It's been my everyday rider for the last 32 years. I may have overdone it when it comes to performance because this thing is a monster now. Just what I had in mind when I first bought it. Thanks for the interest.
love the bike sounds and looks the goods as you stated its what you like, perfect. would you know the jet sizes your running in the mikuni 36 iam in the process to fit the same to my Z1r 1979
I appreciate that, thank you. I currently have the following jetting: Floats are all perfect at 17mm Slow speed - 20 Main Jet - 130 Needle - Middle Slot I feel I'm rich on the slow speed jet, and I will be going back to 17.5 and rechecking plugs as soon as the weather gives me a decent opportunity.
Original Superbikes! Mad Max Specials!! You could help them handle with a DG swingarm and bottom frame bracing and progressive fork springs. Had a KZ 650 and had a ball!! My buddy had a KZ 1300😳🥺😬
Yeah, the stretch and rake make this bike awful in the turns. I have to slow way down, but in the straight away. You better hold on. I've been riding this bike for more than 30 years, but now I've added a lot more performance. I did install progressive fork springs, YSS rear shocks, and braided brake lines just to modernize the suspension and braking. I don't race it, I just built a hotrod. I smile a lot nowadays.
By the way... I think you have CV carbs on. If the carburation problem remains, try to go back to the air filter box. CV carbs don't like individual filters. Otherwise, use flat slide carbs. Good luck!
These are a set of 36mm Mikuni flat slides carbs. The problem that I struggled with all summer was hanging idle. I bench synched the carbs at least 3 times, I tried multiple low-speed jet sizes and new springs on the mechanical advancer. I solved the problem when I did a vacuum sync. Small adjustments altered the idle a lot. Once I was done, it ran great. The only thing left is to fine tune the fuel mixture screws. Thanks for checking out my bike.
@@KZRevival So you are spot on! Good work! You know, it's not good to replace slow jets. You will find by yourself that the mixture screws also work beyond idle. Try to find on the web something about that. You are the best one option to work on your own motorcycle, I guarantee you! You love what you do and you do it well. I'm happy I found your channel!
@@andreferro4618 I'm glad you found it as well. I have some plug reading and fine tuning in my future. I've learned a lot just by being brave enough to jump in their and get my hands dirty.
@@KZRevival I don't know why the FORUMS I am trying to send you are beeing rejected. It's mainly about the mixture screw. If you do some research you are going to find graphics about how each carburetor part works along the throttle opening. They have very good graphics to explain how everything happens. So sad I am not able to send you the one I found... Most people say the mixture screw is only for idle. It works all the way almost to the middle of the throttle opening!
The engine has been broken in since mid summer, I'd say. I was running different slow speed jets trying to correct a hanging idle problem, which i corrected with a vacuum sync. So currently, the slow speed jet is a 20, but my plug reads seem a little rich, and I will be going back to 17.5.
@@KZRevival The idle circuit mixture screw controls work pretty good fer tellin ya what jet size ta use. The screw should be between 1.5-3 turns out from a light seat. Those 36's will tell ya where ta go- best idle when warmed up and ya need more than 3 turns out, put in a bigger pilot jet: less then 1 turn- smaller jet. Don't fergit ta reset idle speed when fiddling and no sync guage hooked up.(ps-mercury guages fuckin suck) If ya run a box fan on high ta cool it, while doin this shit, the engine will like ya fer it. Re-check sync.
@practicalplinking6133 Right now, the pilot is 20, and fuel screw 3/4 turn out. The plugs are dark brown. I think a bit rich. I'll go back to the 17.5 pilot and readjust the fuel screw. I'm hoping for a little better throttle response, but this thing runs a bit hot.
@@KZRevival If yer running B8ES or W24ES-U PLUGS yer too hot plug wise. Drop down in temp to B9 or W27 before ya drop the jet size. 36's are large and the rich(?) at #20pilot may be poor firing do to hot operating. This also leads me back to valve clearance- whatever the cam spec range is, set 'em at the loose end. Another thing- don't just set a mix screw at say .75 turn on each carb. Start at 1.5 turns and run it in and out for best idle when warm.
Yeah, that first one is pretty good. With the big cams I have in the bike, it really starts to pull hard at around the RPM range i was shifting at for the video. It's fun to ride for sure.
@alvinclifton9032 These box steel swingarms are becoming difficult to find, and you only see used ones for sale occasionally. I've owned this one for more than 30 years. Trac Dynamics will make a swingarm for the KZ with various lengths offered, but they are expensive. Sorry, but that's all the info I have for you.
Owned a few Zs since a z650 when I was 17, tricked them all up, just finished an 82 Z1000J 1170 big bore restored in period, modern bikes may be faster...blah blah but they have no soul.
You sound like me. My bike may not be as fast as a sportbike, but it looks a lot cooler. Nothing beats the sound of a souped-up KZ. Enjoy your newly restored bike.
Yeah, anyone that is into vintage bikes knows the money is in accurate restorations. When I bought this bike in the early 90s, I had it stretched and raked then, so I've been riding it over 30 years with more or less this setup. This restomod is about clean up. New Chrome, powder coating, lots of hardware swapped for stainless, wider spoked wheels instead of the mags and the complete rebuild and performance build of the engine. I did all the work myself. This bike was never restored to make money because I've never had any intention of getting rid of it. This is me finally having the financial means to make this bike look the way I want, and I thought I'd post the result because the bike and the work I did make me pretty happy. My kids can worry about the value after I'm gone. Thanks for checking it out.
Thanks. I don't know how to compare them. You would probably struggle to keep the front wheel down, but my bike is stretched and raked, and it doesn't wheelie. This KZ is trying to pull your arms out of socket above 6k RPM. This old-school muscle bike gets lots of attention every time I take it for a ride. It's good in a straight line, but cornering forces me to slow way down, I really love it anyway.
Nice, I was around when the k900 , kz900 and the kz1k came out. They’d pull like nothing else in the day. I just finished setting up a 70 something gs750 for a guy. He went all cafe with it but really screwed up his carbs and timing. I put a Dyna ignition on and set up his carbs for the pipes and ACs he had. It pulls surprisingly hard for an old 750.
That sound reminds me of the original mad max movie.
Made me smile.
@lonelybikr I just watched Mad Max a few weeks ago. All those now vintage bikes. I smile every time I go out for a ride.

No, the green bike does not have a stock exhaust. That is a Delkevic exhaust from the UK. They have a couple of color and style options for the KZ.
@KZRevival it sounds awesome..
4 minute mark for the win!!! Oh yeah.
Yeah, that first one is pretty good. With the big cams I have in the bike, it really starts to pull hard at around the RPM range i was shifting at for the video. It's fun to ride for sure.
sounds great! one bad bike
Thank you, man.
where you get your swing arm? i have a 1975 z1 im working on
@alvinclifton9032 These box steel swingarms are becoming difficult to find, and you only see used ones for sale occasionally. I've owned this one for more than 30 years. Trac Dynamics will make a swingarm for the KZ with various lengths offered, but they are expensive. Sorry, but that's all the info I have for you.
@@KZRevival ok thanks for the info!
Owned a few Zs since a z650 when I was 17, tricked them all up, just finished an 82 Z1000J 1170 big bore restored in period, modern bikes may be faster...blah blah but they have no soul.
You sound like me. My bike may not be as fast as a sportbike, but it looks a lot cooler. Nothing beats the sound of a souped-up KZ. Enjoy your newly restored bike.
Only a few people have this level of perception...
I agree 100%!
wow..........that thing is nasty !
Thanks man.
Needs a restoration... custom oldies arent worth as much.
Yeah, anyone that is into vintage bikes knows the money is in accurate restorations. When I bought this bike in the early 90s, I had it stretched and raked then, so I've been riding it over 30 years with more or less this setup. This restomod is about clean up. New Chrome, powder coating, lots of hardware swapped for stainless, wider spoked wheels instead of the mags and the complete rebuild and performance build of the engine. I did all the work myself. This bike was never restored to make money because I've never had any intention of getting rid of it. This is me finally having the financial means to make this bike look the way I want, and I thought I'd post the result because the bike and the work I did make me pretty happy. My kids can worry about the value after I'm gone. Thanks for checking it out.
@@KZRevival thanks for the reply. Zeds as we call them here are beautiful and yours is tasty has a very nice note...
Sounds nice. How would this bike compare to my Yam fz09 ? It pulls pretty hard too. Nice bike you got there
Thanks. I don't know how to compare them. You would probably struggle to keep the front wheel down, but my bike is stretched and raked, and it doesn't wheelie. This KZ is trying to pull your arms out of socket above 6k RPM. This old-school muscle bike gets lots of attention every time I take it for a ride. It's good in a straight line, but cornering forces me to slow way down, I really love it anyway.
Nice, I was around when the k900 , kz900 and the kz1k came out. They’d pull like nothing else in the day.
I just finished setting up a 70 something gs750 for a guy. He went all cafe with it but really screwed up his carbs and timing. I put a Dyna ignition on and set up his carbs for the pipes and ACs he had.
It pulls surprisingly hard for an old 750.
@megastick9324 For me, that is part of the fun to pull more power and speed out of an already quick bike.
@@KZRevival tinkering is like therapy .
Those ain't hard pulls.....lol. Come for a ride on my ZH2! ;-)
Stop it. I had more. I didn't wanna scare any small children who were watching.
@@KZRevivalclickbait.... lol
