I see OKO carbs seem to have bit of a following.
Are they any better than a Mikuni ?
Try www.OKO-Australia.com.au/

The website works?.

Toying around with the idea of an OKO for my Cota 200 one night I send roger and E-mail with my info. A few minutes later the phone rings and it's Roger we spend a half hour discussing options, bikes and Mid Atlantic Trials.

1987 Honda Reflex 200 Trials bike (TLR 200)
I have for sale a 1987 Honda Reflex 200. It had 400 original miles on it when purchased from the original owner, and now has a hair over 1000. It is completely stock, except for the tires which are new. It is extremely clean and was stored in a shed under a cover. It starts on the first kick, doesn't burn oil, and is a pleasure to ride. The pictures speak for themselves. It has a clear NC title and the tags still have quite a bit of time on them. I believe it could use a stator rewinding due to the fact that the lights are sometimes dim. Asking $1800 please ask if you have any questions! I have no idea what these are worth, if I'm way low or high let me know!

The Honda Reflex (TLR200) is a dual purpose trials motorcycle sold through 1986 to 1987. Both year models are the exactly the same. 1987 models were left over bikes from 1986, re-badged as 1987 models. The Honda Reflex used an XR200 engine in a different frame. This engine was the also used in a three-wheeler made by Honda.

The Reflex also has the tight turning radii typical of trials motorcycles. Its steering column can almost turn completely horizontal to the bike's frame. It's designed to be a stand up motorcycle, though it does have a seat and lights for road use. With light sprocket modifications it is a functional bike for motorcycle trials

I wonder whether or not it would be better to keep the stock air box, as removing this means water can get inside the motor pretty easily? Its possible to make adapters to fit OKO carbs to stock air boxes, and its also a good idea to modify them slightly for trials use, as fuel starvation can be a problem unless this alteration has been carried out.

Reflex uses a TLR motor..........only difference being that Reflex was fitted with US required smog equipment, which means reduced power and is less responsive than the TLR.

XR has considerably more power than the Reflex/TLR, as well as different gearing, ignition system, clutch cover, cylinder head, cylinder, compression ratio, crankshaft.

ATC200 motor is basically the same as XR except it has completely different kickstart which kicks forward, and different gear ratios.

ATC200X motors use different cylinder and head castings to ATC200, and these are worth fitting to trials bikes as the fins are bigger and cooling is better.

Reflex fitted with a few cheap pit bike parts from Ebay, works much better than stock TLR, and the only downside to these bikes over the TLR is the front forks and steel wheel rims.

You are so correct....
Air box was missing when I bought it...
If I could fined one I would be all over it like a blow fly on a turd..
But till then I will make do with a uni filter..
If I have to I fabicate a alloy unit..

Can see your problem...........seems strange you cant find a used air box, as there were quite a few of those bikes made? Easy way to make one would be a cut the shape you need out of polystyrene, making it a little smaller than required, lay up GRP over that and when the GRP has cured cut hole for the intake tube, pour in acetone which will dissolve the polystyrene. Wont look as nice as alloy, but should work fine and will be easy enough to make.

Thats not a silly idea...

I use the build alloy jet boats hull..we put GRP tops on them

PVC foam is the stuff to use..

PU foam cant be dissolved by acetone, so you would need to make filter in 2 parts or cut it in half and join back together.

Means a lot of work which isnt needed................I would tend to make filter with closed top, and cut a hole in it to accept filter element from modern bike.
