Combining 85 kxt with 88kxf

[Tecate250]

Sorry about al that.
Just some info I need to get this bike right.

You really know your stuff.

Funny how you are the only one replying.

you need to get on the 3wheelerworld mainpage and download the JWR Race replica manual from 85. It has alot of go fast secrets and tips on how to make your tecate a true to form race bike. I say get the 83/84 KX cylinder and get it sleeved, get a 38mm Mikuni flatslide carb to go with it and you will have a butt load of power on tap. If not that then have your stock cylinder sleeved, bore it to 295cc's and buy a JS650 seadoo piston and connecting rod, this will give you a displacement of 330cc's. Combined with a good carb and some port work, nothing where u live will touch you. I may know where to come accross an aftermarket swingarm for your bike. As well, if you chose not to rebuild your stock shock then the 2001 Yamaha Raptor rear shock is an almost bolt on mod. The stock pipe is plenty good, just add a DG silencer to enhance airflow and lose weight. Durablue makes wheel spacers to widen the rear of these machines which is a nice mod. Any questions PM me or msg on this thread.

Well, I don't know much but I had both models of Tecate 3-Wheelers for years.

I learned that on the 84/85, it's best to use what aftermarket parts you can get and love it for what it is. Because they are one of the best hi-performance ATVs of all time. The top-end power of that motor stock was too much for most. Take good care of it and it will serve you well. I wanted to come out and say you'd have no problem with a stock 85 Tecate motor against a Tecate4. But I've only ridden a Tecate4 two or three times and they are pretty dern quick. Plus there are so many variables that can affect the outcome.

I don't know why anyone else is not replying. I see James is in now with some more good info. Tecate info has always been in the minority on this board. Lots of 250R and Tri-Z info. Sometimes it seems the Tri-Z info beats the 250R!

there's no reason to add stuff when you hit the nail on the head Jeb. I couldn't have added anything if i wanted to.

[BigGreenMachine]

Cliff you said it, I wouldn't know what else to add.

What kind of carbs did kawy use on the 82-83 kx 250's?
My 84 came with a kehin carb. Size is unknown.
The piston and con rod of that sea doo.
Is that a kawasaki sea doo, and of what year?
Where can I get a new sleve put in?As for my shock problems I have the stock 84 shock but it has been driven way past rebuildable. The piston wore o hole throught the shock body.
Im hopping a 86/87 tecate 3 adjustable uni trak rod with my fresh rebuilt tecate 4 shock( which is 1 inch smaller) will do the trick.

As for color Im hopping to paint my frame Purple. The bright color kawasaki uses on there murder cycles
My tank I painted green to test a theroy about stainning a tank back to color form. So I used my red 84 tank And Im going to paint that white.
Motor Im hopping to keep Aluminum.
My front fork tubes are all rusty. Is there a way to fix this at all?

Im going to put green or purple fork boots on the lower half, just want the top to look nice. My dad told me a long time ago that putting a thicker oil in forks that have bad seals or in my case rusty patches to put thicker oil in there???

I need a vented # Plate

[BigGreenMachine]

It says in my Wiseco catalogue that all 650 model parts are the same. Piston part number is 549M07600 for $129 CDN and the connecting rod is CR150 priced at $136 CDN, you can use all the Tecate small parts like bearings and wristpins. You also need the watercraft rings, bout 20 bucks CDN. Does your cylinder already have a sleeve? If not L.A. Sleeve has one, part #KA795SL for $130 CDN.

The fork tubes will have to be rechromed by a metal chromer. The cost of doing this may be the same as buying a used set off eBay. If you do go this route buy a complete 85 front end to get the disc brake, loads better than the drum.

The number plate is something every Tecate owner wants but not everyone has, just keep a good eye out and dont let up until you find one.

[cliff2302]

i've heard from this board that if you paint aor put decals on a plastic tank you need to seal the inside so the gas vapors won't penetrate through and create bubbles. And 84-5 T3 shocks are the same as 86-7 escept the 6-7s have an adjuster on them. Don't know about t4s though.

[Tecate250]

Both my 84 and 85 have a steel sleeve. But what bore do I need?
Or does the jet ski and tecate use the same bore?

[BigGreenMachine]

Nope, the jet ski piston would be a bigbore piston at 295cc's. But you are halfway there because you have a steel sleeve that has plenty of life left in it to bore. I had to spend alot of cash on having my cylinders sleeved so I now have no cash to buy the piston, rings and have the cylinder bored to meet the requirements.

[Tecate250]

Another thing I waned to know is how to break a bike in, in the winter time?
I usually have to do it at this time of year and I dont want to break or scuff anything.
How much does a big bore kit cost and where did you get it?
Whats involved in putting the big bore on? Do they "drill" out thehole bigger to allow for more cc?

Im asking alot of questions because I really want this bike to be sweet.
I gave up on the purple frame and assesories due to the lack of a good purple in a spray can. Im hopping to get some of my pics scanned.

The magnets on the 82-83 are they replaceable? And is the stator reasonabley smaller then the stock? I have the mystery stator. Its small has no lighting coil. Both my stators had bad spark but the mystery one worked best. How can you tell the difference on the 82-83 kx 250 cylinders/heads with the 84-85 tecate heads?

[Tecate250]

Oops Forgot something. The 84 and 85 tecate uni trak system. Mik6 awhile ago sold me the system off a 84 and he said they were different but not by much. And the 84's had a clutch problem. What was it.

[Jeb]

84-5 T3 shocks are the same as 86-7 escept the 6-7s have an adjuster on them. ....

Actually the 84 and 85 have different rear shocks.

Follow this link:

http://www.files.3wheelerworld.com/Manuals/JWR1.pdf

Go the bottom of page 9.

I need to break out my manuals and brush up on specs, but:

All years had rebound adjustability on the top of the shock body.
On 85 they upped the travel, changed the uni-trak linkage somewhat, and added compression dampening adjustability on the shock reservoir.
On 86 the 3-wheeler was completely redesigned so i'm not sure what the differences in the shock itself is from 85. But on the reservoir they added high and low speed compression dampening knobs.
For 87, they went back to a single compression adjustment on the reservoir.

Whether they all interchange or not, I don't know. I never tried to swap mine around. I bet there's reasons Kawasaki didn't recommend swapping shocks between 84 & 85. They will probably all bolt up, it's just that it changes linkage ratios because of different lengths and shock piston travels between different year models.

If I remember right, the Uni-Trak rocker arm pivot boss location is different between the 84 and 85 Tecate frames. Like on the 85 it was moved a little farther away from the swingarm pivot which is why the 85 has a longer "dog-bone" strut.

[Tecate250]

That explains alot. The bikes all had suttle upgrades.
What is a fresh rebuilt t4 stock shock worth?
