You could start a thread in the "Chit Chat" forum. If and when a Projects forum arrives, you could ask a mod to relocate the thread.

Just a thought... Keep up the good work, and I hope you get a rewarding ride soon!

schmol I have a 2003 zx6r swingarm on my 1978 z1r. I used my original axle with some bushings.$30.00 at the machine shop. You can get that 1/4" off the right side of the swingarm(look closly) I would not try to drill your holes out on your frame the bushings are a simple solution for the axle. Shock mount was simple too I'll try too get some pics soon.B) Mark

Today I made my bracket. I cut a piece of 3/8 plate with predrilled holes to fit. It is metal from an old garage door opener. I mounted it to the chain adjuster, and marked the bottom and side, where the chain adjuster meets the metal bar with a scratch awl. Then I ran a weld bead in both areas of the bracket to keep it from rotating when installed to the chain adjuster with the original locknut..Then, I put it in a vise, heated it red hot and twisted it to match the angle of the left shock absorber. Now the plate sits in an easy to read angle, and parallels the shock from the side. I will need to move it in closer to the chain guard, but at least I can ride the bike now. My test cushion is made...from real upholstery foam this time, and covered good enough to test for firmness. The taillight is fully functional, so all I need is gas. I haven't ridden since Thursday, and am having withdrwal pains!

to those with a ZX7 or other conversions...

Give me your specs.

Fork
Wheels and sizes please
swingarm


Here is my current setup that i do not have installed yet.

96- zx7 forks and brakes.
96 - zx7 wheels

Still looking for a swingarm and clipons so suggestions are welcomed.

I would like to keep this thread as an open dialog for those who have already done the conversion only. This way we can have all the info we need and not have to sift through useless posts (questions are not useless just ramblig oh you know what i mean;))


We need a conversion forum this would make searching so much easier. Hint Stein Hint

'89-90 ZX7 (ZX750H) forks, triples, fender -- nearly straight swap, just need bearing shims with KZ tapered bearings, no machining required. Stem length is great. Reduced steering range, but OK. Steering bump stops just barely allow triple to tap tank. I used aftermarket LSL superbike bars top triple (ZXR750 in European terms).

'90 ZX-11 (ZX1100C) wheels, axles, hubs, and brakes front and rear -- 120/70 17" front, 180/55 17" rear. You can fit anything between 170-190 on rear, but 190 is too big for my swingarm setup, chain hits tire (swingarm see below).

JMC custom-ordered rear swingarm from www.swingarms.com in the UK. Nearly stock length, Z1 as frame fitment, ZX11C as "donor wheel". Kept dual shock setup. Expensive, gorgeous, took forever to get here, turned out I still had to do a lot of mods (including welding) to make it fit. Most issues were due to very wide ZX11 axle which put shocks/chain/sprocket all in the same space. Ultimately had to machine down sprocket carrier (9mm), move shock mounts outboard slightly.

Other miscellany:
- Used PMFR outboard bearing support kit with 7/8" offset sprocket and 530 chain conversion (to match ZX11 wheel). Geared very low right now, but cannot find bigger offset front sprocket, smaller rear causes chain to drag on swingarm unless I lower (use shorter shocks). Fine for everything except long freeway hauls.
- Used aftermarket Lucas rearsets with ZX11 rear master cylinder. Had to modify to fit Z1, though I think they fit later KZ1000. Expensive, great looking, mounted very high (knees real bent!).
- Cut my own brake lines, Goodridge hoses and fittings I think, both front and rear.

Edit: In these deals it is important to remember the variations in donor parts, especially model years. For example: ZX-7 name was used for a long time with substantial design changes. I can tell you how my specific parts worked, but unfortunately know nothing about how a different years part changed, etc.

Elseed great info!

Just so its clear. If i convert my stock KZ bearing to the tapered ones all I will need is this shim and the stem should fit right in correct? Got a part number?

RollingStock,

how did everything fit? What work did you need to do to the front end and the rear? The more details the better this thread will be for future reference.

Galaxian -- re: ZX-7 front end, I KNOW the '89-90 ZX750H stem is a good swap, but I think it's likely the '96 design is dramatically different. That's why buying parts without seeing/measuring them first is such a roll of the dice unless you're a bad ass determined fabricator with significant capabilities.

For the '89-90 ZX7, I had information that it was a good swap. The ZX-7 stem was thinner than stock. The bearing shims are nothing more than "rings" to press into the interior of the standard bearing races of stock tapered bearings. Stupid not to have taken some pictures and recorded better, but I think one was 1mm thick (adds 2mm to stem diameter) and the other was 2mm thick (adds 4mm total) or something like that. I called a bearing shop in town, talked through the catalog, no problem. 1mm thick, OD same as ID of inner bearing race, ID same as OD of stem width.

If you have the parts, best thing is to just start trying to make them fit. For fork adaption, I think it's common to:
1). Press out stem, machine it down to KZ stem specs., press it back in
2). Cut down stem length if too long for KZ.
3). Mate a KZ stem to donor triples (again, requires some machining and/or precision welding).

Well my plan was exactly that. I was..am going to press out the step and machine my own stem that is like the KZ one but fits onthe the zx bottom triple.

I just got excited at the prospect of not having to do that. I compared the 1991 stem part number to the 1996 one and they sort of match.

'96 zx7 44037 - 1339
'91 zx7 44037 - 1295

Oh well back to the lathe...

Marko -- got some measures for you here. Rotor bumping sounds like a challenge.

'89-90 ZX7 triples space fork tubes 8 1/16" apart on center. Fork length is 28 7/8" from center of axle to top of tube body measured at cap shoulder (not preload adjuster, etc.). I was told the '90 ZX-11 C fork tubes are just a bit longer, like 1/4" longer, but use all the same hardware.

These are 43mm conventional forks.

ok. heres my input. some of you probably read the other post. but, for those that have not here goes: complete '02 ZR7S ront end(forks,triple tree's,wheel, rotors, calipers, everything but the handle bars and controls.) since the stock ZR7S handle bars mount up like our stock Z1/KZ's, and even use a 7/8" handle bar. i just used my stock Z1 stuff here. as for the swap, the only thing i had to to do was buy a taper'd bearing set-up from ALL BALLS RACING, with seals. this allowed the ZR7S parts to bolt right up. the bottom bearing is a dead on fit, but the stock top ZR7S bearing will not work. the bearings almost the same size, but the steering stems on the ZR7S is smaller in diameter than the Z1 stem. this is why i need'd a weird size taper'd bearing. the other thing you will have to do is make a new bearing head cup for the top of the steering neck. again, this is due the the stem size difference. i used a baby food jar type lid. while this may sound funny, it was a dead on fit. all i had to do is drill the appropriate size hole, and paint it black. you would never even know, it's even the same gauge metal. after that, the only other thing you will have to do is this. one of the stock ZR7S steering head nuts(there is 2) has a built in dust seal on it. you will have to take this off(it just pops off). then take the top nut and thread that one on FIRST. then take the one that was on the bottom, and turn it upside down( yes it will thread on like this) and and thead it on. this will take up the slack of the dust seal you took off(it would not fit because, again, of the diameter difference in the steering stems) then just tighten the bottom nut, so that the front end moves with ease from side to side, but has no up and down slop in the tree's. then just tighten down the top nut(it is there for this reason. to keep the bottom one from coming loose). then, put on your top tree. thats the hard stuff!! heck, steering stops even work out right!

frontend was pretty much a stright swap with a set of all balls racing bearings for the zx600 and a set for the z1..

the swingarm needs to be cut down to fit in the frame.. the frame need to be drill out so the bigger zx9r swingarm bolt will fit or sum kinda of spacers so the stock bolt will work.. im using a 86 zx600 rear rim/brakes fits in the swingarm with all the zx600 hardware, stright swap.. i have the dogbones bolted where the centerstand was. its a hardtail. i havent rode it like this yet so i duno how its going to work out.. u also have to cut sum the frame out b/c the swingarm is alot widther than the stock

im also using 86zx600 rear sets

Gonehawkn -- Do you know the year(s) of your ZX7 set? Important and helpful info. if trying to buy/bid on something long distance.

Funny you talk about the baby food jar lid. I didn't mention that issue, but the dust seal was a problem for me as well. I ended up buying a stock KZ1000 (not Z1 like my bike, as they don't sell anymore) and putting it on there. But it still rattled around a bit, not quite right. I think I used a modified big mother O-ring thingie and possibly a ziptie after that. This might belong over in the "jury rigged" thread somewhere... :D

important to mention here, is that the ZX7 and the ZR7 are very different, i think, in the front end department. i do believe the the ZX7 might use a USD fork set-up where as the ZR7 uses a more traditional style fork. also, the ZR7 uses a more traditional method of handle bar mounting where as the ZX7 uses clip-ons. that is why i did not go with late model sport bike ZX or GSXR type front-end. i just dont like the looks of the USD forks. i like the more traditional look myself. plus, it was very appealing to know that i would be able to mount up my old handle bars and controls with very little trouble. now, as for the years of the front end. all my stuff came from a '02 ZR7. the parts, when your able to find 'em, usually are much less in cost than the ZX parts.
