If those are the $100 reproduction shocks, they suck on the road. I run ZRX shocks, world of difference.

I use fork braces, and have since 1985 on all of my race bikes...the ancient ones, along with a steering dampener. These, IMHO, are a must and make a huge difference on the old bikes at the limit. Now, you must define the limit, which in my opinion is that 1% of the time you NEED the bike to perform in an emergency situation on the street and when racing these old girls. The old forks with the smaller diameter tubes were not stiff enough the prevent both independent fork action(actually a function of axel strength) , and side to side twisting (walking) and bending under load (front to back) . The brace helped all of the this. Now, the down side, that load is now shifted into the frame , tires, and springs....at the limit, normal riding you can't really tell. A well balanced bike will have both the front and back re-enforced. Properly done and these old bikes can can handle extremely well. To me nothing feels so neutral and sweet as a smoothly setup Gpz550/KZ550 twin shocker. They just got it right. And as proof to me in 1985 was the article in Motorcyclist about the master Keith Code using KZ550's/Gpz550 in his super bike race school.

Get a set of decent rear shocks like the ones off a Zephyr or ZRX and add a set of the Cartridge emulators with decent oil and the right springs; you'll be amazed. And it's easier than swapping front ends...to me anyhow....and cheaper.

Finally got around to installing a set of Cartridge Emulators into my forks last weekend, with 10w fork oil. I'm blown away by the difference; they used to bottom out on braking and nose dive, no more. They actually dampen now...high speed and low speed. They were a little too big so I had to turn them down, this allowed me to exactly fit them to the inside diameter of the forks for a perfect seal....which I found out the fork tubes are 5mm thick...thats pretty stout. I'm still tuning them, but overall I'm very happy. I'm trying keep the period correct S1 replica look. Larger modern forks would change that..maybe later down the road I might upgrade them, but for now since I had these, I'm going play around with them. Next thing I'm going to do is get a set of preload adjusters from PMC, and upgrade the springs with the right rate. I think the oil weight could be upped too. I put zip ties around the tubes to measure travel on both. Comparing to the old setup the forks bottomed completely...and "bouncing" caused sever unbalanced pogoing on the front. ..and at a different rate than the rear upgraded zrx1100 KYB shocks. I'm going to get a fork brace as well to stiffen and stop any independent fork action.

They will never be as good as modern forks, but, they are 10 times better than before.

Downside, to adjust them you have to pull the emulator out...and it can only be adjusted for compression. Rebound is adjusted using oil weight. I'm looking at ways to modify the emulator for rebound.

Hagon, Ikon (Koni), Progressive, and another, the name of which escapes me at the moment, are, I think, the most popular choices. Ohlins if you want the best and are willing to pay quite a bit.

Some folks have reported good results using the KYB shocks from a ZRX 1100/1200. Even used, these can be expensive, and may after so many years need rebuilding, which can be more than $400.

The KYB shocks from the ZRX 1100 and the 1200 can be rebuilt. Places like Daugherty Motorsprts will not only rebuild them, but can do custom valving and springs.

Those ZRX shocks are great but man they are getting pricy and cannot be rebuilt.

Used ZRX KYB shocks
I bought a low mileage set of these for my 83 1100 shafty and have been pretty happy with them.

Thanks, it's a work in progress.

Current list of bits an pieces:

Early 18" GSXR wheels: 110 front, 150 rear.
Dynatek 30ohm coils with large copper leads.
Iridium NGK plugs
Mikuni RS 34DS FS (pumper) Carbs <<< Maybe should have gone bigger.
Individual Cheap'y pods. <<< Might get K&N
Vintage Original Kerker pipe
GSXR Rear brake
Not in photo CBR600 F3 front brakes.
PMC KZ1000R ELR S1 replica rear sets from Webbike Jap.
ZRX1100 KYB Rear shocks
Progressive fork springs.
Racetek Gold Valve Cartridge Emulators for the forks.

I really like the old race bike look, the original MKII and KZ1000J race bikes...and of course the S1. I started thinking of maybe emulating some of what DoctorGamma did with his MKII. (Thats one sweet bike).

One thing I'm not sure about it is to go full tilt on the whole ZRX parts upgrade or stick with original wheel size and basic suspension. (with upgrades). I have a full set of ZRX parts because I also have a 2000 ZRX with lots of cools parts too. This sucks though, last summer I was wipeout by a jerk on his phone and did some damage to the ZRX and me. Thats why I have some spare rex parts. Putting the ZRX back together now, still need to get the tank painted.


Wishlist:
AP calipers and rotors
84' gpz1100 bathtub head
hot street cam (web or crane or Yosh?)
repaint...everything.


If anybody that has a Zed with the 17" wheels and the ZRX parts I would like to know what the handling differences are like? Right now I can putt along in first at idle and do figure 8's lock to lock with near zero effort. I try that on my cbr600F3 and it wants to fall into the turns and you have to muscle it around (and its 150 lbs lighter).

Old “newbie” in Central NY was created by fastfrank

Hi, guys & gals:

I’m currently resurrecting a few bikes, which have been sitting idle for up to 15 years, and trying to get myself back in the saddle after too many years with medical issues.

I used to ride in the San Diego & Escondido area, then moved to upstate NY (closer to Canada than the city) around 13 years ago.
Being out of commission for so long, I’m anxious to enjoy some Adirondacks and Catskills riding now.

Aside from the little Suzi GW250 for my teenaged twin boys, my only running bike is my 78 KZ750 Twin, although it isn’t always idling well.

I’ve been working hard on resurrecting my ZRX1100 for the last couple of weeks, and it is now running better than it ever did (for me - 2nd owner), but I’m waiting for a new battery so it can be untethered from a car battery and get some new rubber dirty. Along the way, found that I had a broken #3 carb body, which likely happened shortly after I picked it up in Chicago to ride home - in the rain in Lake of the Ozarks, MO, a lady pulled in front of me, I bottomed out the fork, and sustained a separated shoulder. Rode home to San Diego with ibuprofen that didn’t really help, a broken right peg, and various scrapes and contusions.
Hardest part of this refurb was treating the tank... lots of steps and manual shaking with a chain inside.

My 83 GS1100ES is also in-progress, waiting to finish the VM33 carbs and get them back in, de-sludge the oil pan, and get new shocks and springs on to get it back to a sane height - it was a lowered and extended drag bike before I bought it. Still ran great on the street, before a stator problem sidelined it.

I bought the KZ Twin here in NY a couple of years ago, and I’m about to pull the BS38 bowls off to see how it is jetted - I understand they benefit from bigger pilots. It has an aftermarket 2-to-1 pipe, and a K&N filter in the stock airbox. I have a few jets to try, I suspect it’ll end up around 130 mains, 50 pilots? (My first BS carbs.)

Anyway... good to be here. Looks like a huge wealth of hard-earned bike lore and expertise here.

Cheers,

We're using KYB's shocks off of a ZRX 1200, the wheels are 2017 R1's, having the outers polished and the centers painted to match this gold on the shocks.

Motor is getting powder coated black, hoping this will be on the ground running before end of month. I got the frame back today from blasting, start adding gussets and trimming off unnecessary tabs and brackets. Someone had cut the rear turnsignal mounts off, if any one has a bad chassis that they could cut the tail off of, I'd be interested in it.
