ajsfirehawk makes an excellent point! Carefully check the bottom rear of that fender to see if it has been modified. Some had the struts wrapped around the back of the fender and attached to holes as in ajsfirehawk's picture, and some had the struts attached to tabs on the fender as shown in the image below. Someone may have modded your fender to eliminate the holes or the tabs. In any case it looks like there's a lot of unsupported fender there that might cause a problem if you hit a bump. Ed

If the front fender oscillates enough to catch the tread while you are riding, it is going to be a $hitstorm. Take a hard look at it partner. A pic of my 79 D2 for reference.


Thank you for your feedback. When I got the bike these was missing and I have driven one season without, so I will look into it, but properly have it like now.
Like the design better, if the vibration will give any problem will I think about cutting the lenght of the fenders instead.

From internet image searches the KZ650-D4 may not have Fr fender stays, and the 1981 KZ650 manual doesn't show the stays. The JarleF Z650 site has a pic of a D4 without them as well. However, it seems odd that there are 2 holes at the rear of the fender.

I think the two wholes is for «mudflap»?

I only see the CSR model for 1981 KZ650's. I think you have a 1980 year of manufacture KZ650. Here is the link to the Partzilla front fender for your model. It has the wrap around style strut and those two holes are for mounting. The fenders that don't have struts are shorter. Longer is better for road crap/rain being thrown on you, and your pipes but if it is a look you are after, shorten it up. I would not leave as is without a strut. Party on.

Kawasaki made a 1981 KZ650-F2 (and 1982 and '83 F models) and to my surprise it has the long front fender with no struts. I don't know if any of those models were imported to the US. See link below. Ed

Have same tires on my bike, I like them, and will buy them again.
I have a 1980 Kawasaki KZ750 Ltd. I bought new. I recently managed to get it out of my garage after 28 years and put it on the road again (2010). I feel like a kid all over again. Since I have acquired 3 78 KZ1000 Ltd, 1 1981 KZ1000 Ltd, and another 1980 KZ750 Ltd. Love the LTD's.

I've got to believe those models don't have two holes on the back of the fender. Makes me wonder if there was some additional structure inside to avoid oscillation.

Those fenders rely on rivets so it makes sense they would need extra bracing. The Z1/KZ1000's are one piece.

I will looking into replace the fender in the future, don`t like the way its mounted with the bolt on top... more smooth design the fender you have linked to.

Today have finish rebuild the engine, installed the last shim I have waited for in the mail. Now the valve clearance is between 0,10-15mm and approx around 0,12-0,13.
I have installed new "cop holders" over the shims, after that is was easy to measure the valve clearness so the old one was properly not 100% flat. I have also installed new carb. holder (rubber inlet). I will soon install the engine in the frame. Looking forward to it :) Hopefully can I start up the engine during the month.

When I cleaned the old front light reflector it damage it.. the silver layer was going of... so I have order new reflector, the old look to be orginal, so it was properly time for replace it anyway, so get good light again?

I removed the brace and bent the tabs inward when I first got the bike for what I feel is a cleaner look...... never had a problem although the 78 fender looks to be maybe a little sturdier.
Am looking forward Gordone to you firing up the bike....... you've done a fine job on the bike and worked your butt off on it so I'm hoping all things work out great.

The fender is mounted same way as before, I have only driven the bike for one season, but there was no problem then. It feel werry stiff, its some metal plate on the inside to make it more stiff...

In the future I will look more into the fender, I don’t like the design 100% the way its mounted to the front fork with the bolt nuts showing on top.
But these the cool thing always something to improve. I’m plaing to rebuild the eletrical system in next phase, maybe next winter.

I’m looking forward to firing up, hope not the oil leak everwhere and its coming alot of white smoke out the pipe hehe :)

Yeah the fender always looked like a bird beak to me. I like the LTD genders. Shorter and more stylish. B)

Yesterday I moved the engine into the frame, it was my first time and it was not so easy... heavy engine.. :)
I tried to protect the frame with some plastic "rollers", it worked okay, it was not much hit on the frame.
I started to mount some of the cabels, will take the rest of the cable and then the chain etc...

I have some private task with my family today and tomorrow, if it was up to be I will been outside working :)
Looking forward to start the engine up :)

Today have I installed the chain and exhaust. I have started a threat for the chain, want to verify the lock on the chain looks good:
www.kzrider.com/forum/2-engine/608232-install-chain-correct

I have also started a threat for disc brake lock, I want a good one, not fun to loose the bike after all work has been done...
www.kzrider.com/forum/5-chassis/608233-disc-brake-lock

I have a idea maybe I can start up the engine on Sunday, but I don`t want to stress it... (not easy) hehe the weather is start to be good...
want to drive... :)
