    I have just become the husband wives love to hate, brought home another XJ. Does anyone have, or has the ability to find any details on the 29R. I have tried all sorts of searches and get diddly. My 650H has lots of info though.
    I have a puzzel to put back together, a wiring wizard has been at work,AGHHH.

    I have tried without the year in searches and still nothing.

    Yes, I was goin to say that the 29R code is showing to be a 1983 XJ750E-II, which is a Japan-only model, an XJ900 frame with the 750 engine.........

    Wow, that's interesting.
    I have heard stories of Servicemen stationed in Japan that brought bikes home with them not available in USA.

    If all the numbers are right ... maybe you could take a few photos and post them.
    Let's see whatcha got!

    Look at the VIN number stamped onto the frame steering pipe neck, or, if this bike still has the paper tag on the steering neck that shows a (hopefully) 17-position VIN number, let us know what those numbers are (or the VIN number from the paperwork registration or title). That will be a big help.

    Do you have Hitachi or Mikuni Carbs?
    If you have the bike I think you got; there will be Mikuni's on it!

    Nice machine; too.
    Too bad your are in NZ ... I have a 900 Engine that needs a new home!

    its got the Hitachi carbs. The frame Number is 29R000801.
    I found a reference on a german websit which said only 880 were made.
    I will do some photos tomorrow ( its dark here ).
    The bike came from a shop which had traded it in in 2006, it was driven in and then failed to start again.

    Hi Guys.

    [​IMG]

    [​IMG]

    My 1984 XJ750E-II, also in New Zealand. The 29R was first released in Japan in 1983. It has the 749cc engine fitted to the XJ900 chassis. There were a number imported into New Zealand, mine in 1996.

    Serial numbers begin 29R-000101, mine is 29R-001131 (perhaps Chacal can help decipher this for me).

    My restoration to date is here:

    http://homepages.slingshot.co.nz/~shanetp/XJ750.html

    From a manual perspective you need to chop and change a bit, I use the XJ900 Parts and Service manuals for most things but you'll need the XJ750 manual for the engine. The wiring doesn't appear to resemble either.

    I still have a plug coming from the gauge cluster which doesn't appear to connect to anything and everthing still operates fine :?

    It really is a lovely bike, Hitachi Carbs, anti-dive, twin discs front, single rear, air assisted forks.

    My 900 has a Speedo, Tach, Fuel Gauge and Digital Clock.

    I'm thinking that extra Plug you have must power the Clock.
    Nice bike!
    I like the color, too.

    My 900 Book has a few pages about overhauling those Front Fork Anti-Dives.
    I actually got them apart and managed to get the inside piston traveling freely within a nylon bushing.

    Now, I have three setting up there for Anti-Dive.
    When I go visit my sister, out of State ... I just turn them off!

    Likewise the E-II also has the tacho, speedo, fuel gauge and clock. The digital clock display also doubles as a trip meter. The clock works fine and retains time with the bike switched off. I've had the cluster apart and the loom in question definitely connects into the circuit board in the clock/trip area, unfortunately it remains a mystery as there is no corresponding connector on the bike loom (and it original with the 29R part number tag)

    Like you I've had the anti-dive apart and freed up the piston. The manuals all say don't touch or can't be serviced but the 900 service manual has a page or two of info and I like a challenge. Mine has a small threaded rod acting on a spring and the plug, accessable from the bottom. Unlike the plug or bolt shown in the manual this threaded rod is quite small with a slot for a flat blade screwdriver, there are no positions as such, you just screw it in or out to any position you want.

    Thanks for the compliment, I like the colour as well :D

    Thanks great help.
    I have found a sticker hidden on the rear guard, hidden under the grime,it says XJ750E-II its a 1986 and was imported to NZ in 1990.
    I have managed to get it to start for about 30 seconds then nothing. It wouls appear the ignitor has passed its use by date. Its currently got a ER & D Electronic Ignition Box, [M. S 510 ]. Kiwi do you have the original in yours ? If so what is the Type number, if it follows the 650 it should read TID XX - XX. I would prefer to have an original but if thats not possible then an aftermarket one will have to do. My forks hav had the anti dive removed and blanked off, the air assist is still there though. Also looking for a new fairing and from whats been said the 900 will fit.

    Hey KIWI and NZJOHN, just looking over your info, you say that your bikes are 1984 (KIWI) and 1986 (NZJOHN) model, by chance could you check the full VIN's of you bikes and let us know what the model-year code (in the 10th position of the full VIN, right before the letter "A") is?

    The XJ750E-II models should all be 1983 models, meaning that 10th position of the full VIN should read "D". It would be a "E" for a 1984 year-of-production bike, and a "G" for a 1986 model.........

    I'm betting they got titled when sold as the year they were sold in. It used to work that way in the States too, the dealer would send in the original title "origination" paperwork. That's why we have 1976 and 1977 Norton Commandos running around when there was no such thing. The numbers stamped on the frame/engine tell the real story.

    During the rebuild I searched the whole bike, the only VIN serial numbers are 29R-001131 stamped on the RHS of the steering head and a Vehicle Transport New Zealand (VTNZ) 17 digit VIN tag pop riveted to the fram by the air cleaner with the number 7A8JH3Y11960001131. I believe that these are VTNZ generated VIN numbers for vehicles imported into NZ without a full 17 digit VIN from there country of origin.

    All the 29R's originated in Japan and were brought into NZ either privately or thru bike shops importing them (Japanese imports of used bikes and cars has been all the rage in this country for the last 20 years).

    My understanding is that to encourage the purchase of new vehicles the Japanese Government loads the compliance costs of older vehicles until it prohibitively expensive to keep them on the road there. The purchase price of older (7-10 years) was very cheap. The rage in this country especially in the 90's (and has continued with cars this decade but not so much with motorcycles) was to travel to Japan, buy the vehicle at an auction and ship it back here. Car (and motorcycle) dealers soon cottoned on to this and the avalanche began.

    I have 3 pages of the 29R spec sheet (all in Japanese unfortunately) and the serial numbers begin 29R-000101~

    My registration papers indicate the vehicle year of 1984, this is the year first registered in Japan, year of manufacture - who knows.

    Kiwi, thanks for the update. Yes, that 7A8..... number sounds like it is an "assigned" number from your Dept. of Transportation (or equivalent). I appreciate your assistance!
