So want this...........

Chuckie25 · « **Reply #1 on:** October 25, 2013, 05:02:18 pm »

I've got 3 now (granted 2 are retired racers and are just rolling chassis) and raced one in a few XC/hairscramble races against R's and X's and it's my favorite trike, after the ATC110. The one I raced on was lowered a tad, port/polish, re chambered head, DG pipe, 36mm Keihin and it was a SWEEEETTTTT ride.

I think I'm gonna go to a 200X front end on one of these 3 I've got now.

The cool thing is is that you can throw an 89 YZ250 head and cylinder on one (as well as some other parts, not gunna make a full list) and then you've got a powervalve motor just that quick!!

Video just loaded for me.

That's a member of 3wheelerworld's 85.5.

And,, That's not a restoration. That is a resto-build.

I really want a three wheeler for my collection. Just to have and pull wheelies on. Maybe dune once in awhile.

85-87 ATC-R or 85-87 ATC350X.

The 86/87 R has the pro-link rear suspension and are the BEST riding trikes around. But they fall short because the forks blow super easy and are about like our LT rear shocks.

The X is a TORQUE. FREAKING. MONSTER. Talk about LOW. END. and they will stil ru! like a **** ape up top!!!

Since you would be a first time trike I recommend those (and mostly the X) so you can learn on them.

And then you get an (85) A1 or (86/87) B1/B2 Tecate 3.

A1 has the fatty front tire, non-KIPS engine and are WICKED MEAN.
The B1/B2 have the KIPS engine and the saddle mount rads.
The Tecates actually handle MUCH better but have a LOT more power than the Hondas. They are violent. And there's still LOTS of aftermarket support for them. Everywhere from big bores to pipes.
They are bad about the rear shocks like our Suzuki's.

The Tri-Z 85, 85.5, 86 Tri-Z is a larger machine. They fit a bigger/taller guy better and with a good port, rechambered head, good pipe, carb combo they will run with the wicked Hondas. Harry Klemm is building 346cc big bores for these again. That's 346cc on stock stroke as well. >:]

I'd recommend a first timer getting a 350X or 85/86 R (you aren't goin to find an 87 R or X but they DO EXIST. It was recently confirmed by Honda Canada that they sold some true 1987 model units)

I appreciate the info sir.

So those Tecates were violent eh? - time for some Youtube.............

Chuckster,

What water cooler 2 stroke 3 wheeler is the easiest to get parts for? Restore? Etc;?

Dangerouspower · « **Reply #7 on:** October 25, 2013, 08:08:56 pm »

My guess Honda. Am I right cj?
edit: now on the top posters!

Chuckie25 · « **Reply #8 on:** October 25, 2013, 08:14:31 pm »

The easiest to RESTORE: Tecate or Tri-Z.
I doubt you'd wanna pay the $80+ For an OEM 85 ATC250R front brake hose.

Easiest to RESTO-BUILD. Any of them. Honda's are a good learners bike.

Plus stay away from the tecates until I have one. There are only 2600 of them. (Or was it 1600,,, x600 but less than 3000 lol)

I had an '84 kxt250A1 Tecate.... Put a kx cyl & head, 38 flat slide, coffmans pipe & silencer, RAM steering stabilizer

It was the fastest 250 at the time!

Triz and 86 Tecate will be the hardest to restore. Not much left OEM for them. Tecate and triz both luckily can use a dirtbike engine. So that helps some.
Best trike to learn on is easily the 200x handles good not overpowered. Easy to find .

Chuckie25 · « **Reply #11 on:** October 26, 2013, 06:40:30 am »

Kennerz, which Tecate was it with the stupid low production run then? The 87 B2?

I personally am saving to get an 85 A2. The 84 A1 is the fatty front tire but drum brakes. The A2 has a disk.

All the Kawi had stator problems but swapping in a KX250 ignition solves it basically.

And like Kennerz said. You can get them dirt cheap in Cali. That's why I'm saving. $500 for a bike, $500 for shipping. And I have a good base/starter project Tecate. I got a buddy who'll hook me up lol

Also like Carl said, the YZ250 is a bolt in swap for the Tri-Z, just gotta swap clutch covers over to have a forward kick and you've gotta swap in the Tri-Z kicker shaft.

Not 100% sure of if the KX250 is a bolt in swap for the KXT. I know you can put an 85/86 quadracer engine in one though!

The '84-5 Tecates were electro fusion Bores similar to nikasil. The kx cyl & head were bolt on & rip

What about the old air cooled Honda ATC 250R? Anybody got any feedback on them?
