Update...

The bike is more or less done. Though there are two "issues" left on the "To Do" list..

1. I am waiting for the new Italian wheels. -Yes, I lost my fukn mind and went and made an order for a set of OZ Piega wheels...
2. I am also debating with myself about buying a Slipper Clutch assembly. One does get around the issue of a "skiping/locking" rear wheel with rev matching on down shifts, BUT one will not get it right every time, and the time one gets it wrong - it's a terrifying feeling...
..... 3. Depending on what I decide about the Slipper Clutch I still need to do an oil and filter change...

any way... A little walk around and engine running video... Bike Video - Click Me!!
Thanks!

Ps. I will put the mirrors back on the bike, the "mirror delete" plates were just a test on how the bike looks. I will only be using them when I ride the bike at the track. Riding with out mirrors in traffic is kinda dumb anyway, and also here in socialist Sweden highly "Jesus God Almighty we are all going to die" illegal....

Mefirst...Beautiful ! Looks and sounds tremendous. Can’t wait to see the wheels
And yes on the slipper clutch. I’m considering one too. What are you looking at ?
Excellent project ?

Cheers CMG!!! and -Thank you!

The order and delivery time on the OZ Piega wheels was/is 6-8 weeks, so I am still waiting on them. I did look at the Marchesini wheels to, but I found out that Marchesini does not make wheels for the ZX12R any more (they do, but only carbon fiber wheels, which is kinda an overkill on a street bike and not to forget insanely expensive). So if someone want's to roll on Marchesinis, you need to find them used or if you are lucky, some dealer might still have them...

About the Slipper Clutch. I will probably go with this company KAWASAKI: Slipper clutch for motorbike KAWASAKI ZX12

..But I also know these other three..
Sigma Performance (UK) Kawasaki ZX12R 2000 Onwards Sigma Motorcycle Slipper Clutch
STM (Italy) Wet Slipper Clutch Stm for Kawasaki Zx12r 2013 - Fkw-s085 - Slipper Clutch - Engine Parts - by Stm - -This assembly looks beefy...
YoyoDyne (US?) Kawasaki Slipper Clutches

These four companies still make slipper clutches for the ZX12R, though there may be others to..

I think one member here, Smiffy (don't know if he is active any more though) used a Sigma Performance slipper clutch in his bike...

Hej Tom

Nice 12...are those Bandit/2 pot Nissen's on there? After struggling with the big Tokicos for a while I just got the Nissens instead, bolted straight on and took like 5 minutes to bleed.

Please put the bike's ears back on, it's bad enough you ripped it's wings off

Enjoy

Cheers Rules*

-Yes, you are correct about the front calipers. Nissin # N4PL/N4PR, one of the best and cheap upgrades one can do to the ZX12R... About the side fairing wings. The "China" fairings did come with the wings, sadly though the china dude who was responsible for the "wing" machine messed something up in the manufacturing process, so the wings would not fit worth s..t.... I will put the mirrors back on, the mirror block off plates were just a test of how they fit the upper fairing and will only be used when I take the bike to track days...

Short update..

The weather was kinda ok, it is still cold but the sun was shining so I took my bike out for a first ride. -Damn I have missed riding a motorcycle. I was smiling ear to ear the whole time. Put on some good bike riding tunes through the Cardo system and away I went.... I did not even stop smiling when the gear shifter almost fell off. I had forgotten to tighten the shifter rod nuts. I had also forgotten to tighten the two nuts that hold the clutch cable in place, noticed this once back in the garage after the ride. I was also happy to notice that my leathers had not shrunken during the winter, actually my leathers fit me better now than they did last season... I got about an hours worth of riding, after that my fingers were more or less frozen to the bone and I could have cut glass with my nipples... But a bike ride was what I needed...

My OZ Piega wheels will be delivered on Monday or Tuesday at the latest. I am still missing the rear sprocket for the Piega wheels, well sprockets, I bought/ordered two Supersprox Stelth sprockets. I am not able to buy aftermarket wheel sprockets anywhere locally. Hope I will get the sprockets by the end of the month so I can finish the bike. I have also bought a set of Bridgestone S22 tires. I am really looking forward to roll on the S22's and compare the S22's to the Pirelli Diablo Rosso III tires I have rolled on the last two seasons....

Take care...
/Tom

Ps. Riding a bike with out mirrors in traffic just sucks, I do not recommend it... Mirrors will be bolted back on the bike...

A happy day... I picked up my OZ Piega wheels today. And these wheels look so nice!

16407


16408


Front wheel. I was a little worried for a moment that OZ had forgot to add the front wheel spacers in the package, but I realized quickly that you reuse the OEM spacers.. Any way, I can not deny that for a moment my blood pressure went up...

16409


About the rear wheel. The sprocket carrier seems to be a really tight fit. I am gonna lube it when I put it together. I am pretty shore it will be a basterd to try and take off if you put it on dry...

16410


Pic of the underside of the sprocket carrier...

16411


Upper side of the sprocket carrier..

16412


I just had to test fit the wheel. The only concern left is that the front and rear brake discs will line up with the calipers... I will report back about that later on... I mentioned in my previous post that I will be rolling with Bridgestone S22 tires this season. Hope I can mount the tires with out messing up the wheels... I am still waiting for the chain sprocket/s... I will reuse the Brembo front brake discs but will sometime in the future change the Brembo discs out for a set of EBC discs with the gold center. I have a new EBC rear brake disc. I have a set of titanium brake disc bolts for the front and rear. I also have a set of gold titanium sprocket nuts...

Thanks!

Absolutely Beautiful Tom. What is the weight difference? The looks department is covered. They are beautiful. Do you have a part number for the rotors??

Cheers! Yes, the bike looks really nice. Though it is 20 years old, it is right now more or less a brand new sports bike. I have not got a scale so I can not weigh the wheels, but my guess is that they weigh about half of what the stock wheels weigh. Brembo Oro rotors # 78.B408.A1 You can buy the rotors through Ebay, that is where I bought the set I have.

Update... "Winter ZX12R Project" is more or less completed ? I am happy...

16455


Two things remain on my "To do" list. -Bolt on the Black Widow header/down-pipes and an oil/filter change.. Well then there is the "Wish list".. I will buy a slipper clutch later...
Bike has rolled 20 years now and with all the work I have put in over the winter, I bet it will roll another 20 years....

Cheers CMG :coffee:

I will post more pictures later on. Bike needs a wash and I´m stuck at work.. and typically it is going to rain this weekend when I am off work...

I do have to say though that I did not notice that much of a change with the OZ wheels as I had hoped for. I feel the change has more to do with the Bridgestone S22 tires.. -Damn these tires are good!!! I highly recommend the S22, the hype about them is true, they are that good...

On a "sad" note...

The bike has developed a weird noise. When I turn the rear wheel there is a "light clonking" sound. I have pinpointed the sound to come from the front sprocket area. I hope it has to do with the front sprocket. The front sprocket has a rubber damping ring and I think the sound comes when the chain rolls over the front sprocket the rubber lifts the chain a fraction and when the chain rolls over it, that is where the sound originates, at least I hope.. There is no alarming amounts of free play in the sprocket shaft, bolt is torqued to spec... any way, I have to investigate more. There are no issues when riding the bike, everything is working as it should and I can not hear or feel anything wrong. I noticed the sound when pushing the bike into the garage. The sound is the same pushing the bike forward and backwards.. Front and rear sprockets are new as is the chain. I use a laser to line up the chain, so it is straight and the chain also rolls over the middle of the teeth on both sprockets.. Chain has 30mm measured up-down movement.

Did you find the noise?
cmg
Cheers CMG :coffee:

-No, I have not had the time to do any further investigation but I am on my way to the garage a little later today.. I will report back about the issue what it was if I find it.. or do a video and post it here so you guys can help me figure out what is going on with the bike... I have been thinking about it and last time I was out riding I did have one "incident".. I was playing around with a guy in a BMW and when I overtook the car and shifted from 4th to 3rd managed hit a false neutral.. But as I wrote in my earlier post. There is nothing wrong with the bike when riding it, all gears work, no vibrations or anything else that would have caused me to worry something is wrong...

Update....

Well seems my paranoia has reached new levels.. Ooh well, better safe than sorry... The weird sound did originate from the chain. I loosened the chain and the sound disapeared. Set the the chain tension again and all is well. I have no idea why the chain started to make that weird sound. Tried to think of a reason but just can't think of any. The set up is right now exactly the same as it was before, but with out the sound.. I also did a filter and oil change while I was at it... A side note... Motul motorcycle oil is by the way the best smelling engine oil in the world 😊

Not sure I can make a definitive guess, but when I used to run a belt drive, if it was a bit tight and had some weight on the passenger side, it would whine like crazy.

Sounds like the chain might have been a bit tight or had a passenger? Oh Yea, and a rubber cover over the front cog? Never heard of that.

Jpowell490* It can be that the chain was a little to tight the first time around even though I measured the slack to 30mm.. But the weird thing is, it did not make any noise at first, the noise came later and after I had been out riding the bike. About the front sprocket.. No it does not have a rubber cover over it... The rubber is on the side... The rubber is supposed to act like a "cushion" and to make the chain run smoother around the sprocket... Here is a pic of the type of front sprocket I use (JT Sprockets #JTF517.17RB)
