I have a T3 motor, I got of some one awhile ago, how do I know what year it is? Can I tell by the VIN or what else should I look for?

 

Is it liquid cooled? If so I am pretty sure it's an 86. I don't knnow much about the T3's so I guess I can't really help you.

 

Yes it is liquid cooled but the 84 and 85 models were to.

 

If you could post the vin#, I probably could look it up for you!

 

The vin is KX250DE006197.

 

86 had kipps (powervalve), 84-85 do not. 84 and 85 are identacle, all are water cooled.

 

The computer won't give me anything on that vin#.
I did look up the motors to see what the differences are.
I only looked at the four wheelers and not the three wheelers, if you think it's a three wheeler let me know!
The 87 and 88 are the only four wheelers in the computer, the only difference between the two are the carburators, the 87 is a a-1 carb that should have a 260 main jet in it, were the 88 has a a-2 carb and it should have a 140 main jet in it.
The number you gave me might be off the motor, you think you can get the one off the frame.

 

Hey Gaff, I think he identified it when he said 'T3'. That means a Tecate 3-wheeler. Also, A1 and A2 refers to the respective model years ('87 and '88) of the T-4, and does not relate specifically to the carburetor. The A1 had a Mikuni round slide carb, and the A2 had a Keihin PWK (d-slide) carb. Completely different. Also, there where changes in suspension geometry between the A1 and A2 models, very slight, but I believe they were significant enough to prevent you (for example) from swapping A-arms between the two models. While I may seem like a wealth of knowledge on the T-4, unfortunately I cannot add any more information as to the T-3, but I think Warrior007 is on the money. One more thing, I would be suspicious of whether or not this motor is out of a T-3, judging by the the VIN#. I haven't looked closely at my T-4's to see if the VIN# starts with 'KXF', but I'm assuming they do, and a T-3 motor VIN# would then start with 'KXT'.

 

I got the same type of back lash when I was referring it as the three wheeler from a guy sitting next to me, you know the one I mean, the one who can resight what year what mod, and what magazine to look it up in, well I just thought I would look it up.
Not all the years are in the computer anymore.
The a-1 and a-2 don't only describe what generation the engine is but what generation the components are, such as thiers three different carbs for the 88 model, but only one carb for the 87.
I seen the frame differences but you know how that goes that old, doubt I could get all the facts rite.
Well any way, I looked all the ones up that are on the computer still and can't see any type of difference to tip you off any way, sorry about that.

If any one cares, this knows damn every thing sitting next to me says it's not a tecate motor at all but a kx motor, I don't know sorry I couldn't help.

Yes I just slapped him so don't worry about him getting on here.

 

No problem. I figure between all of us pooling our resources and knowledge, we'll get it straight (someday). I was unaware of there being 3(!) carbs available for the '88. My factory service manual only identifies one (the PWK). I would be interested in finding out if this is, in fact, true. Unfortunately, somebody had swapped out the original carb on mine (before I purchased it) for a Keihin PJ (you know, the one with the idle speed adjustment as the choke ****?), and dammit, I HATE those carbs. As a matter of fact, I posted here some time ago because I can't get the dang thing to idle. It starts easy when cold (a little fussy when hot, but not significantly), runs cleanly through the entire RPM range, is jetted spot-on for the type of riding I do, but neither the idle adjustment or idle mixture screw do ANYTHING to make it idle. (and I've been through the carb about a dozen times looking for a blockage, but it's clean as a whistle!)
