This is pretty much what i'm after (but red), but with a bigass 2 stroke powerplant. (500Two LOL)

As for yz/it 490 having their issue, stock yes. Cleaned up no. Modern carbs do wonders for these air cooled monsters. As for the wr500, it was actually very reliable.
The reason I tossed the it motor into the picture was due to the lighting coil, but you can throw a battery operated light on there though.

lighting coil.Doesn't Service Honda make lighting coils for cr500's from 84 and up?

TS400, bullet proof bottom end very tunable engine.
ANY disc valve Kawasaki Big Horn(350) or Bison(250) engine , bullrt proof bottom end and tunabilty is off the scale.
Disc Valve Can Am/Rotax 244 again bullet proof bottom ends and very very tunable engine.
YZ490 is s complete shitter the 465 is much better.

Although I do have patterns for a three cylinder ( 1050cc ) case reed engine just needs a gearbox cases added to the pattern. I haven't owned a road bike in 30 years ( XS1100 last road bike ) and look at the modern road bikes with distaste, all the same. A large twostroke twin or three would be quite nice I'd say.
Good looking Honda though.

So the motor is the width of a triple plus a clutch basket.
Is it possible to put the clutch gear between cylinders 2 and 3?
That would do wonders for making the engine compact
Post by: 2T Institute on May 02, 2013, 12:46:06 PM
I think what you need is a Tandem twin 700cc, cylinders tilted at 30 / 40 degrees forward, gearbox underneath, one chamber forward and under the bike, other out under the seat. 140 HP. Chrome molly ladder frame and spoke wheels. Nice fat noisy chambers. Well that's what I would like! I've often thought about such a cafe racer. As 2T says anything with Rotary Valve.

Carlo Mattaroti has already done similar though just 250cc.

The three cylinder cases shown have the take off between cylinder 1 and 2
These are aviation engines with only a gear reduction. I have posted these before.
Make a great cafe racer engine ( three cylinder should be good for about 200HP ) Where would all the chambers go? Perhaps reverse the middle cylinder? Sorry don't want to hijack this post, just wouldn't it be a great project with a little time and money spare?
Post by: Jeram on May 03, 2013, 12:14:59 AM
so as not to get offtopic any more:
Can you email me with a ballpark of what you think it would cost to mate a gearbox up to that motor + produce the motor.
you made the very smart choice to put the gear in between cylinders 1 and 2!
I think I wouldn't mind building a 1070 triple in a year or two once the other projects are out of the way

Look up Carlo Mattarozzi on FB (he's got a VERY nice Villa 490) he just made it for something to do. I think the crank gears are paired and the clutch runs off one gear Neil he just made it and put it in a frame he made, just to do track days on. Carlo is apparently a old school Italian craftmen with a CNC shop at his diposal. He recently made Morbidelli MBA copy engines.

Lolerbabop Just post up what you do looks an awesome build idea. I'll sell you an 82 it250 motor that I have for $150 + shipping haha.

Ok, screw this!!! I'm gonna do something smaller... Like a Zundapp KS125 1976. Just gotta build another seat and strip it of everything unecessary and it'll be one sweet cafe racer.
just attach some fake cooling fins to an RM motor
Post by: Lolerbabop on May 11, 2013, 08:23:41 PM
)
Then make it look like this:
But with all red tank and side covers with the exception for the "ZUNDAPP" and the "KS125 SPORT" logos and a fat expansion chamber.
I will swap the fork with one from the later ks125 models with disc brake on the front. (Cus i want that...) Then i will look into if it would be possible to machine a hub out of one of those solid alu wheels that the newer models sport. (DISC BRAKE) Gonna snatch the hydraulic clutch and front brake master cylinders from a bike which ive seem to have forgotten the name of.. Then steal the slave cylinder from whatever hydraulic clutch kit i can find for a cheap buck. Then it's just a ****load of small things left, that no one will probably even notice. Like relocating the horn to underneath the tank. *Sigh* Lots of things to do... First thing is to find a suitable bike that's not too far away and is for sale.
I will create a build thread as soon as i get a hold of that damn KS125.

I saw a pic somewhere of a CR 500 af made into a café racer, looked very coolI hate those... They look alot better with the older steel frames.
Post by: Lolerbabop on May 15, 2013, 10:02:29 AM
It would be pretty easy to make an older looking bike out of this thing.
So what do you guys think of machining a wheel HUB out of one of those solid wheels that's in the picture above? I'd like to have spoked wheels with a disc brake on the front like on the newer KS125's.
Here's another view of the front wheel.

Post by: Lolerbabop on May 15, 2013, 04:55:18 PM
I'd say it would be easier and safer to try and find spoked wheels to fit. Drilling 36 holes into a hub not designed for it might be a recipe for disaster.Yeah i kinda figured it might become a death trap, but still.. And i would only need a hub that fits. I think... But im gonna try and get a hold of one of those rims and see how much material there is to work with. Priority number one is to find a damn bike to work with though. The front disc brake hub spoked thingie is dead last. I'll just use the solid wheel if i have to untill i find something with spokes that works.
