    Gday fellow riders. I have a few queries for you.

    Love motors, new to bikes, about to get my Ls again and last week i put a deposit on an 89 zx2r.

    Shes in need of a few things. Chain tensioner, cables, clutch, brakes, some body work n other bits and bobs.
    She also has a cold start issue where she needs to be revved and then choked pretty hard till warm but then runs fine. Any ideas what it could be? Maybe just needs a good carb clean and sync?

    Supposedly she has upgraded carbs, but unsure if its just jets or complete carby upgrade. I will inspect when i pick her up.

    Since the deposit ive been non stop looking for parts and of coarse upgrade options on sites ive found like

    Japan Webike
    Wemoto
    Slipstream Performance
    Motorcycle Spares Warehouse
    eBay
    Partzilla, OEM parts

    Im sure im forgetting a couple, but does anyone know of others?

    Whilst browsing i came across these, wandering if anyone has tried them?
    http://www.ebay.com.au/itm/Derestri...tion-/280665295126?hash=item4158f48916&_uhb=1

    Theres a similar unit on Japan Webike
    http://japan.webike.net/products/21125979.html

    Some leads that look the goods but cost an arm and a leg.
    http://japan.webike.net/products/242204.html

    As for brakes, what are some good street discs and pad and where to get them? Any advice for chosen materials?

    Will eBay spec discs like these do the job or are they complete rubbish?
    http://www.ebay.com.au/itm/Front-Re..._Parts_Accessories&hash=item43b856c497&_uhb=1

    http://www.ebay.com.au/itm/Front-Br..._Parts_Accessories&hash=item53f9f5c8cd&_uhb=1

    Clutch, EBC or Ferodo is pretty much what ive found. Any other suggestions or advice?

    As for upgrades, i know of the CVK D32 Keihins. I presume they are extremely hard to find?

    And finally (i think), whats some good sprocket ratios to gain some torque and not lose tooo much top end? I was thinking 13/49. Brings the final drive up from 3.43 to 3.77. Thoughts?

    Cheers :D

    Hey mate looks like your getting into it quick. Congratz on the ZXR. A few points from my perspective.

    Cold start issue is probably just the carb settings. One of the first things you should do is take em off and clean them out. It's likely they've not been done for years if ever. Check your float settings while in there, it may be running a little lean. Once you've done that a Carb sync is also a for sure thing to do.

    Check the tank as well!!! If it's full of rust and gunk no matter how well you do the carbs it'll ALWAYS need cleaning again. $90 bucks for a clean, proof and seal tank kit will be the best money you ever spend.

    If they are saying the carbs have been "upgraded" they may have changed the jetting, the most common carb mod. There's a few other more.... controversial mods out there like drilling out the slides but I'd avoid doing them to an older bike.

    Japan Web Bike - Dear god I hope your rich! But high quality parts.
    Wemoto- Never ordered from but looks good
    Motorcycle Spares Warehouse- Affordable, super quick delivery, my fav shop to get stuff from
    eBay- All hail Ebay

    Your not missing too many websites, 90% of the stuff I get is from Ebay or MSW. Although I highly recommend findapart.com.au makes getting parts from wreckers simple as.

    As far as those de-restrictions go they do work BUT they remove the rev limiters and if your gunning it and go from 1st to N not 2nd you could shred your motor if it's not healthy.

    As far as the leads go don't bother spending so much money. Pop down to your local mechanic and buy some suitable lead yourself. The spark plug leads are easy as to make and attach to your existing coils and caps.

    Now brake disks...... I'm gonna be controversial here some people on the forum will disagree (Chris :D ). The Chinese ones sure they're not the most intense disks in the world BUT they are not evil. Avoid buying the silly shaped ones and stick to the round disks, the silly shaped once almost bend in your hand. AND ALWAYS put new pads on when you get them. Does not matter if your ones are at 1% wear new disks new pads. There are Aussie made ones you can get though, high quality and very durable. They'll cost about twice as much for the set I think.

    Clutch. If you want to save money and keep the stock. Get some heavy duty clutch springs and new disks. 89 ZXR uses the same ones as KX125 and are available from any dealer.

    CVK D32 Keihins..... if you find a pair tell me so I can buy them first. Other upgrades inc Airbox, New CDI, Muffler, jetting etc. If you do a muffler it helps to do jetting as well.

    Sprocket ratios.... I like stock so I wouldn't know what to suggest.

    Hope that helps you a bit mate. Good luck with the rest!

    Heres a post I made earlier but was lost in the server changeover ..... Doug has it well covered but Ill throw in my 2 cents worth anyway ..... :D

    When u buy a new old bike you should give it a major once over especially with the 'safety' and maintenance items
    I think you need to get it running correctly before jumping into upgrades, performance items etc.... and if youre new to bikes you may find the stock bike performs above your expectations...... the inline 4s of this era are known for their above average 'performance'

    Dont take much notice of what previous owners tell you ...... if you troll thru the threads on here you will find plenty of examples of shoddy work or just lack of it.

    Change all the fluids , including the fork oil , brake fluid,coolant, check the chain and sprockets , check the age of the tyres not just the tread depth.
    Empty the fuel tank...look for crud or rust ....check for internal filters, the inline filter ..... no use having clean carbs if the source is dirty.
    The carbs will no doubt need a cleanout .... and a kit (o rings etc) ..... and thats the time to check the jets are correct.


    You have found the basic sites for parts etc ........... always try ebay.com and .uk

    Have a read here to decide what brake pads suit you ...

    http://2fiftycc.com/index.php?threads/which-brake-pads-to-choose-organic-sintered-or-ceramic.1591/

    Try here for the discs .... avoid the Chinese ones

    Many thanks for the informative replies I will start a project thread soon.

    That gearing commander is awesome!! And thanks for the other links, very helpful.

    First things will be safety, maintenance (all fluids etc.) and cleaning up any shoddy workmanship, then I'll start on upgrades.

    Just had a quick look at kx125 clutch kits, wemoto has an ebc dirt racer kit for about 160 aud posted including friction plates, steel plates and heavy duty springs. Being a dirt racer kit can it be used on the street without issues? Motosport.com had it even cheaper. Do all year kx125 clutch kits work on the zx2r?

    What parts are interchangeable between a, b, c and d models?

    Anyone fit velocity stacks/trumpets to their zx2r?? Would love to hear that induction sound! !

    What about a good place to dyno tune her in Sydney? ? Don't know much about tuning carbies

    And I would never fit new rotors without new pads lol :D

    I've used a fuel tank kit before worked great on our rusty old xb ute tank.

    Should the clutch basket cushions be replaced also?

    My assumption is yes. I got the clutch plates of my mechanic so I can't say for certain the exact model of Kx125 they were off. I didn't get a spring from the KX125 so not sure about if they work, just a specific ZXR one from Ebay.

    Probs check with your mechanic about the dirt racer kit not sure on that one.

    As far as parts go the A/B models are very similar, same with the C/D. The B/D are just the "R" spec special edition of their respective models. You may have difficulty with a number of parts interchanging from the A to C as the bikes were significantly redesigned between the two. The actual engine tho remains identical as far as I know across the two main differences being body, electrics and other cosmetic features.

    NB- The ZXR manual on the website is for a C model, however much of the information is still relevant to an A

    Great thanks.

    I am my mechanic lol, no one touches my vehicles except myself and my business partner. Except of coarse for tuning.

    Although I will talk to a good moto mechanic a friend takes his gixer 600 to. See what he has to say about tuning old bikes. He's well renowned and a sponsored racer.

    Has race bikes for days in his shop lol

    Nice :)

    Well let us know how the tuning goes, especially if you end up taking it to a dyno. A lot of us tend to tune our bikes from trial and error. I'd be interested to know how much/how well getting it done by a dynotune works out, or if they can even do it on the annoying ZXR setup.

    After removing and adjusting things about 2^98 times you get pretty sick of doing so :prankster:

    Lol Yeh I would imagine it would be pretty annoying to dyno tune a carby moto. My business partner knows his way around carbies pretty well. So after we sort everything out and start doing some upgrades and pick some sprockets thinking 13/49 or 13/50. We'll see how she pulls on the Dyno. Hopefully gain a few kw and a bunch of newtons.

    As for the bike performing above my expectations, I'm sure it will. But I'm 6 foot 3 and weigh 70kg, I think I'll get used to it pretty quickly. Plus with some upgrades and sprocket ratios I "MIGHT" have a chance of keeping up with my friends on their bigger bikes lol

    I'm heaps keen to get her on a dyno to see how much power she's list over the years. I'll only need a LAMS legal bike for 1 year 3 months because I'm over 25 but I don't think I'll want to get rid of her because she's rare. Might end up keeping her and in the future fuel inject and turbo her lol for the track

    If that's even possible (inject or turb) and you end up doing it you must let me know! :D

    Is just hopes and dreams at the moment lol but I don't see why it wouldn't be possible to fuel inject it. It's just an inline 4, same as my sr20 lol

    An ecu with a loom made up, a bunch of sensors including wideband, custom intake flange, itb's n trumpets. Then to work on ignition.

    Would be a fun project. Although an endless money pit and time consuming lol

    Thanks mate it actually looks much tidier in the pic. She needs new paint. Thinking of matching her with my s14 there in the background.
