XJ750 RL what exactly is it ?

This is kinda doing my head in ... I have an XJ750RL.. the questions are

1. Is the chassis an XJ900 ? and do all the associated bits fit it ? i.e. fork springs etc etc. My 750 does NOT have anti dive ....

2. Where did the motor come from ? is it a Maxim motor ? a 750 seca motor ?

Just trying to work out exactly what it is that I have ... oh, and it looks like this

 

Re: XJ750 RL what is it ?

You got it.

It's pretty much a 750 Seca motor in a Seca 900 chassis.

From XJ4Ever's writeup on model IDs and VINs: http://xjbikes.com/Forums/viewtopic/t=14577.html

Listed under COUNTRY: CANADA:

"MODEL NAME: XJ750RL
STREET NAME: 1984 XJ750 Seca
MODEL ID CODE: 44X
FRAME ID: 44X
SERIAL NUMBER STARTS AT: 000101
NOTE: 750 engine in an XJ900 frame. Approximately only 600 made."

Nice bike!

 

Drill down into this site and you can compare part numbers by model

...some bloke on th innanet told me that there was about 900 of em put together outa th parts storage area at yam an' about 280 of em went to oztralia an outa that lot you will possibly still find variations ...... for instance

Good buy, and its odd that there are so few, yet they keep appearing in ebay and elsewhere.

 

Hey, nice looking bike, I've seen a couple in here before. As far as the anti-dive go's, consider yourself Blessed not to have it since depending on the age on the Bike you would probably be re-building that also now. Looks like you have yourself a nice set of wheels there, enjoy the ride but go through and check tire numbers, rear brake shoes, front brake lines ect. to first make sure that time and age are not demanding some repairs. grunt007, 81-XJ750 Seca R, Mi.

 

I've got one to,and yep 900 chassis and 750 seca motor,mine has no anti dive on the forks either.

 

@ Bigfitz... cheers. This ones a 45T model... Oztralian one ... same as the canadian one but different designator. I'll sift through that thread.

Adrain and Bushy ... looks like I have more threads to get through... cheers.

Incidentally, this one is a (now ex) Tasmanian bike. Brought it back to the mainland on Monday night via Spirit of Tasmania...

 

Jeez that bike is super clean!

 

No it's not.........there's a LITTLE smudge under the M in YAMAHA.

Good find!

My xj900rk just received a First Place trophy today

thanks for the replies guys. Its not in too bad condition for its age. Has 48000km on it which I believe to be original.
It's a 20 foot paint job.... the closer you get the more blemishes there are. Needs some work to put it online properly... brakes, carbs, valves etc etc... in other words, some TLC.
I'll start a thread when I'm ready to get into it and post up some pics etc etc...

 

They have a different Camshaft in them (longer duration) also the carbies have some extra vent/intake hoses up the top of the carby. Rolling frame is all 900 stuff.
My 2 RL's do not have anti dive.

 

We should start a 45T list of owner/bikes on here so we can compare notes & see how many actualy are still around.
8O Check the frame for fatigue cracks just behind the seat latches, all 5 of my bikes have been repaired there. :?

 

Another Aussie with one

A register could be interesting.... I have 109

 

Hi Roadbandit,

I have one as well.
I picked it up at Easter 2011 thinking I would have it on the road in about 12 months.
I'm not there yet, but getting closer.
Hopefully by spring time!!
Where are you located?

Cheers,

Tim

 

Wadeys is now in my garage along with seven other XJs that I acquired from him (my wife thinks I have a problem!).
Its build date is 12/83 and number is 296.

 

Hi
I have 160 and the motor out of 365.
Rebuilding 160 as the oil nozzle was getting eaten away by the hi-vo chain.
Hope to be back on the road soon.
Rob

 

thats a lovely looking bike rmunro13. Are they by any chance still the original exhausts ?
if not, any ideas where to get a set ?

 

My is 2/84, number 45T 363, not as good as the ones pictured, even worst now.

 

Ozroadbandit - That's a Motad 4 into 1. Stainless steel headers and chrome exhaust.
I ordered through Wemoto and cost about $ 500 AUD landed.
The exhaust doesn't quite fit as it should as the rear bracket doesn't line up correctly with the stock mounting points but a small length of steel fixed that problem.
I asked Motad what exhaust is the correct one fits the XJ750RL and they replied that their XJ750 fits all...they lied. Maybe the XJ900 one would be a better fit.
Engine now in the frame and I will be terrorizing the streets of Perth soon.

Hi All,

Just joined the group, picked up my XJ750RL yesterday.

Ozroadbandit I have your older brother 45T-000108 built 11/83

Cheers, John

 

Some nice looking RL's there. Mine's a bit of an ugly duckling in comparison.

45T-000149 here

 

Can't help myself!
I just won number 45T-000242 on eBay.
It will eventually look good sitting next to 45T-000108
Looks very very rough, but it's mostly all there.
The best part is it was in my home town of Goulburn NSW, no travelling to collect it.
Cheers, John

 

My thoughts are that Yamaha was in a bike-building war with Honda, and built soooo many SECA 750 motors - that they ended up putting some leftovers in the "900" chassis, the "TURBO" and "650" chassis as well, then continued to build "Police" bikes.

This would require them to stamp the VIN on the motor during assembly.

Notice JONMARQ's motor is silver, XJ750RL's is black.

 

I don't know why but all the Red/Silver XJ750Rls seem to have black motors while the Blue/White ones have silver motors.
It also appears Australia only got the Blue/White version and the Red/Silver was Europe and Canada.
Does anyone know the production dates for the Red/Silver colour version, Interested to know if they were built as a second production run.

 

Hey Johmarq.... 108...I have your bikes slightly younger brother ...109....

@ time to ride .... Australian XJ750RL's use an unpainted motor.
I had mine hydroblasted and not a spot of paint on it.
Canadian RL motors may all be black though ?

 

There goes 45T-000317, frame mainly, au revoir...
http://www.ebay.com.au/itm/yamaha-xj-75 ... 4ac16f08d7

 

There's 2 in BC ... one's for sale.going to look at it today (1)

http://vancouver.en.craigslist.ca/rds/m ... 35086.html

 

Time a few of us (Aussie) 750 45T owners got in touch ... any takers?

Mine is 45T 000194 registered and running but has carb tuning issues related to mismatching carb slides ... presently sorting.

 

Since nobody's really answered this for you: what it is, from a North American market point of view (parts wise especially) is essentially a 750 Seca motor in an XJ900 frame and bodywork.

I'm not sure about Canada, but down here us Yanks only got the 900 for one year, '83 (XJ900RK.)

 

Here she is ... just as her maker intended

Incidentally these scans are from a pristine original sales brochure I have for this model .. I'm going to get hi res scans done and have it printed up as a wall poster for my garage ... If any of you 45T owners would like a copy PM me and I'll do it at cost plus postage.

 

And if looking at a brochure like that doesn't send you off for a polishing session in the garage ... nothing will !!!

There is some ambiguity over the R and RL designations ... from what I can make out they are identical, if you know otherwise please let me know.

Essentially it IS a 900 frame with a 750 engine, BUT it has HSC33 Hitachi carbs with Y18 needles, #41 pilots and #106 mains so do not expect US 750 Seca carbs to be the same.

The US models also seem to have two small breather holes in the carb slides whereas the Aussie models had one large one. You need to refer to the manual "supplement" for specific regional differences. PM me if you need more info.

The other main differences are:

No anti dive
Low ratio gearing
Three dial instrument cluster per "some" XJ900's (which?) My 900 has the two single instruments, the drop bars and the short fairing but it is the year later model)

Also .. the TCI's are not directly interchangeable .. but the loom can be modified to suit

The 750 has an Australian compliance plate with R on it but all the service documentation refers to RL ... I know of Australian models with RL on the compliance plate and mine had an old rego with RL on it ...

 

Well that's very interesting ... and uh huh after reading the fine print .. thanks for the clarifacation.

 

The R means Seca, the L means 1984.

The tci will be different because it's a different engine.

the 900rk should have the same three-guage set as shown on the 750rl

The carbs will be different because the engines are different

USA 750 secas were other years. We did not get the 750 RL

The fairings were the larger frame-mounted fairing not the small fork mounted fairing of the early 900rk's.

Not sure what you mean by the 'drop bars'

As you're signature indicates that you have a 1985 XJ900, there are going to be differences from the 83 900rk, and the 84 750rl.

She's pretty alright, just as she is :lol:

 

She's pretty alright, just as she is :lol:

 

Turns out I've got #123.
More like 122.5 actually at the moment though!

 

I was under the impression the 45T had a longer duration on the cam as well.

 

Huh. I never knew that later XJ900's got a bigger fairing. The bodywork is identical to the FJ600. Wonder how that happened...

Looking closely at all three, it's amazing the similarities. The only major difference I see is the rear grab bar. The 750RL also featured FJ1100 style rear view mirrors, I notice.

FJ600/XJ600:



XJ750RL:





XJ900:







Check out the identical rims and rotors on all three.

Would love to see all 3 in person or at least side to side.

 

Would any of you Aussie boys have a decent tank for 1 of these. Im lucky enought to own 1 but the tank is too badly rusted to be reussed, It has been at some stage had a liner put in it but thats failed and breaking up.
So can anyone help me get this old girl back on the road?

 

Hi
The 900 tank is the same & may be easier to get hold of.

 

This guy may have something

http://www.gumtree.com.au/s-ad/redwood- ... 1019789658

Also drop a line to this guy

http://www.lookmotorcycles.com.au/index.html

 

Thanks guys, Ive sent of messages to both those guys. Yes im aware the XJ900 is the same, but theres very few of the xj900 or that model XJ750 over here in NZ. I did find 1 guy with a tank but his was just as bad as mine.

 

I'll check out some wrecker here as a few say they have XJ stuff. 8)

 

There is also findapart.com

 

Mines up for trade so I don't take a grinder to it, also have the Cowell but it's rough
