XT600 - Model Codes
 

Lifted straight off the Tenere Forum and bought to my attention by Mezo (Mark) on another thread. I have placed this list on the Service Manual & Parts Manual's sticky's on this Yamaha sub-forum.

Mine have JYA3UYE what is the J? YA= yamaha?

No idea xtrock? :(

I think both mine are 3TB's - 1999 XT600E and a 2001 XT600E. I presume from this that the quoted dates may need updating on the list?

My 1999 XT6E was brought in Warsaw, Poland by a British soldier serving in NATO. He rode it home a year later and I bought it off him. I still have the shop receipt and import docs etc.

I will update the dates when someone is able to confirm they need it. :smartass:

Yamaha finally hit the STOP button in 2004 with the XT600E model....:(:( PITY! I think it would be a huge seller today...

Ok i found it, J is for Japan.

Universal VIN Decoder


1st character- Identifies the country in which the vehicle was manufactured.
For example: U.S.A.(1or 4), Canada(2), Mexico(3), Japan(J), Korea(K), England(S), Germany(W), Italy(Z)


They still have the XT660 so they didnt stop making the XT? I have been riding the HD Fatboy and the HD Ultra classic(450kg) and i tell you the XT felt like a bicycle after, but damn the XT is easy riding in the city, with them big bikes you have to always think how to stop/ park and get the balance right before you stop..For me its importan that bikeriding is easy!

I'm not convinced by that list, Neil - I think your XT6Es are both 4PTs, being from the 1996(late-95?)-2003 period (not sure of the 3TB chronology stated there, nor 'one or two' others - E.g. wasn't that later Swiss variant a '4SL7' and whatever was a DJ021).

3TBs preceded them (the 4PT, that is) from 1989 only as far as 1996 or late-1995.

Be careful before importing other websites' error into the venerable HUBB :nono:

Just for the record the 3UW is a restricted 3TB.

I don't know the extent of the restriction (i.e. jets, headers etc) but I know the carb rubbers were different.

In all other respects they are a 3TB.

Bigfoot
Its OK if you are not convinced,no one will push you into that.I have made it with an official yamaha dealer codex.There are listed all yamaha bike builds from the first to the last in 2010.:thumbup1:
Now you could at least tell me why is that an error?
Karl

Er... Thanks, Karl.




I thought I already had. Neil's (and my, and many others') 4PTs seem to be listed as DJ021 and the Swiss variant of the 4PT, the 4SL7, seems to be listed instead in the 3UX row. I don't know what else is questionable within that list but the complete omission of those two models and their inclusion within a different strand would seem to deprecate it as a definitive guide. It might be 100% accurate for the older models, though.

You say you "made it with an official yamaha dealer codex" but not THE 'official Yamaha dealer codex'... And all I can say on that score is that my local 'official Yamaha dealer' (UK, 'EUR') understands and identifies with the 4PT model and so, it seems, does his dealer parts system and other Yamaha 'literature'.

Checked the original yamaha codex today.
We are talking of frame codes.Not engine codes.4PT1 started with the 1995 3TB.It goes untill 4PT9 from 1999.Then it changes into 4PTA and ends in 4PTB in 2002.
4PT9 starts with new frame code DJ021......
Its not an error.You mixed codes:thumbup1:

Oh I seeee! Right, frame-code prefixes - NOT model codes. That makes far more sense, particularly as some of your quoted frame-code-prefixes do double as model codes.
Not my error: you mixed words :thumbup1: (or titles/headings).

Why don´t you make an complete list then.....it looks you know all better.
So we can all use your bullet proof list,not mine that is full of errors.....:thumbup1:

I have a US '88 Xt600U and the code shows a 3EW, but the list shows that as an '89, plus it was states the first character was for the country. I don't follow that one especially when the US is supposed to be a 1 or 4 and mine has neither number in the entire VIN. JYA3EWE5JA******

JYA= Japan, its not like all the bikes in the states are UYA, i quess import and company getting bikes in those days ment for selling in Japan.

What?

I thought you said your list didn't have errors, and that we had misconstrued the codes as being model codes - because of their heading being "Model Codes" - when in fact they were prefixes to the frame-codes. Well, it seemed to confuse Neil and I was somewhat bemused too.

No need to get arsey about it, Karl - I was merely pointing out that NO! I didn't 'mix codes', you mixed terms. You can't say that they're actually not what you listed them as - especially as many of those frame-code prefixes do actually equate to the model code! - and then claim that is our mistake and not yours.:nono: Bloomin' cheek!

Bigfoot2,I still insist that non of the XT 600 models is called by the engine prefix code.If it works for you that an XT 600 E its called 4PT then do so.
Bring me an parts catalogue from your dealer where that 1996 XT 600E is printed as 4PT on the first page then i change it on that list,have no problem in update it.
You pointed out first that the list has an error.So show us why.Simple as that.And don´t play with words,things i didn´t write.:nono:

Neil kindly made a bunch of them available from the XT600 Parts Manuals (1990 - 2002) thread at URL = http://www.horizonsunlimited.com/hub...0-2002-a-48399. There's copies there for 4PT (model-number) models from 1995, 1999, 2000 and 2002. I downloaded the 2002 one for myself some time ago, which does have "4PT" on its front page - which is how I knew mine was a 4PT (model number) - so I'd guess the others do too. It also has the aforementioned 4SL7 there. And yes - my 4PT does have a "DJ021..." frame-number. It also has "4PTB" on its model label affixed to the frame under the seat. 4PT does not seem to be any kind of engine number, though - it is the model number. The engine number on mine does not have a "4PT" prefix (according to the logbook), but I might have got the wrong idea there about what you were suggesting. Engine and other parts numbers/references will often have a "4PT" prefix, though - or "3TB" or presumably other non-XT model codes - if they were introduced for that model and used in the overall development of the bike.

I think the 4PT was 'officially' imported to South Africa and a lot of Western Europe.

Hope that helps.

This doesn't:-
"You pointed out first that the list has an error.So show us why.Simple as that.And don´t play with words,things i didn´t write.:nono:"

Well, we can trace most of those qualms back to me querying the lack of an entry for the 4PT model within the Model Codes list (which is clearly what had confused Neil, by the way) and asking whatever a DJ021 model was. After being a tad rude, you pointed out that these were frame codes not engine codes (nor model numbers?) and that I had got the codes mixed up. Well, it seems - and I say again - that it was you who mixed up codes: DJ021 is the frame-code prefix for the 4PT -model-, isn't it? Having said that, it seems I did misconstrue the whole list to be actual model codes - and I think they mostly are, it's just that the only one that I could be completely certain about (that of my own bike) had a code listed for it that is not its model code.

As for 'playing with words, things you didn´t write :nono:', I don't understand that one and you may need to check what you actually did write.

In the interests of world peace an' all that, I hope the info' at the top of this was useful to you and I sincerely apologise for any offence, but would qualify that...:-
- the original point was in answer to Neil's apparent confusion in relation to the list that he had sourced from the Tenere site;
- I hadn't expected to directly answer to the original compiler of the data in question, on this site (lesson learned! :blushing: );
- there was a certain nonsense in being told that they were frame-codes, not model-codes as listed, and that I was wrong in questioning that they didn't all seem correct as model codes.

Anyway, I trust the above info' is useful to you (and maybe to Neil, in identifying his later bike), and that we can all be friends again.

1993 3uy eac?
 

I saw this subject got a little sticky, but I have a question to add. I am new to XT's so bear with me, I have a 1993, JYA3UY, but my repair manual says EA and EAC, is there any logic to these letter codes on my manual? I was given the impression that the E would be Electric start maybe?

Your manual covers all models, there is no difference due to the letters. CA california models have some few difference on the frame parts and tank, tank is the canister on the fuel line, frame overflow pipe. I quess California have special rules about emissions.

In the US (probably all other countries as well) every year is designated by a different letter in the model name(the numbers on Walters manual).
Example in '86 it was xt600S , '87 was XT600T, '88 XT600U, '89 XT600W,
,e-start (letter E added)started in 1990 and was XT600EA, then '91 XT600EB , '92 XT600ED , '93 XT600EE , '94 XT600EF and '95 was XT600EG. All years had a separate model for California due to emissions changes and the letter C was added to the end of them aka '93 model XT600EEC. Most changes were just leaner jetting in the carb otherwise same bike. Not sure with Yamaha but other brands had charcoal canisters or re-circulation systems to stop all those nasty oil and gas vapors from killing the world single handedly. Wonder how thats working out .

Awesome, thanks to everyone who contributed to answering my question, I've only had my XT for a few months and I'm trying to do some upgrading to it, all the info I can get is a big help, especially in the parts search. So one more question, which it looks like you have already answered, but for clarification, the only difference between a 3TB amd 3UY is country of purchase?

Serial numbers
 

Hello from Canada.. hello everyone I am new to this site have been reading articles time and time again, but I finally signed up. I live in Manitoba and I am the proud owner of a 1993 Yamaha XT 600 E. I had been trying to find out what this bike has for horsepower. I believe it is the three TV engine. The engine serial number is 3UY-018228. From what I’ve read in some of these articles The 3uy are a version of the 3tb engine and possibly restricted hp. I have put on a dominator exhaust system and complete header pipe, so it is less restrictive and possibly more horsepower. If anybody could fill me in as far as my horse power rating before my exhaust system was put on that would be great.thanks rob from canada

35 RWHP is the most i heard out of a non restricted 600, more likely 32-34, and that, IF the bike is in vgc.

most people dont like to hear this but aftermarket exhausts help mostly with lower weight and healthier sound, not so much with power, even if we'd like to think so :)

Is that with rejet?

an open pipe without a rejet will be way too lean and make even less power than stock.... dont ask me how i know :)

Yeah I know, but was wondering about the Arrow pipe since I'm thinking about getting it. It comes with baffle too.

that specific dyno graph is not mine but reflects well my experience, not just with my XT600 supermoto, but also with other bikes. when i installed a no-name straight-through open silencer on my xt600SM it became too loud for the liking of the track owners, so had to install a silent baffle anyway. still needed to go up a bit with the main jet to restore throttle response.

best if you can take the bike to a dyno to find the best main jet. that's what i do with my roadracers,

with my "training" xt600SM it's not that critical, went with feel of the pants.

Mine was 37.2 on a street tire (supermoto rim) But I was more impressed with reaching over 50Nm at 3500rpm.

Aftermarked header and silencer, top of the airfilterbox removed, and kn filter insert in the original airbox.
Carb overhauled with a china-rebuildkit (love thoose)

The dyno didnt seem optimistic when I looked at what everyone else got, some were pretty dissapointed :innocent:


Bike was at 180.000km, with a fresh piston at around 160.000km as I recall.

Need to figure out the year on 600cc Yamaha
 

The only numbers I can find are stamped on the headstock: 34K-001031 and 595 on the engine...

Thanks!
