Yep they're the ones, reasonable price too, although postage could be a killer.

If you view the Ebay listing through the Australian eBay site you will get the current price in both GBP & $Aus instead of GBP & Euros.

am i right in saying that that photo off the ebay listing shows the front of the carbs (facing away from the head) and the other picture listed on auction as the rear? Is there a bit missing on the rear? or does the manifold bolt straight onto the bolt holes around hole?

The side of the carbies shown in the picture in Chris's post above is the side which joins to the manifold. They are joined by short pieces of rubber hose, with hose clamps on both the manifold and on the carbies (as shown in the picture this thread relates to). The trumpets are part of the airbox which we got with the carbies and they bolt to the other side of the carbies.

iiiiii seeee. Thanks for clearing that up.
Im seriously thinking about this. Only major hurdle would be either finding some decent ones in nz or getting some in and then making a manifold. Might be able to get one of tnpshows flanges and just cut some piping on an angle and i have a welder die grinder and angle grinder..... mmmm

I suppose you could say that the easiest part of the job is making the manifold to carb flanges. [there arent any]

The carbs secure directly to the tube with the short rubber sleve that Aiden described.

The beauty of these carbs is that they were designed from the outset for 'pulse flow' [1 carb 1 cylinder] They were never intended to feed more than just one so the whole design is optimised for this function.

im going to try modify a twin webber manifold dont know how good it will work but if it goes ahead im might write up how i did it....

The manifold looks so simple and effective.. Dodgeman, You are right about the particular sound this engine makes on bike carbs, it is rather crisp to say the least.

Aiden, the racecar is really coming along this year, nice one, you are set to be on the heels of CP in no time.

If by chance any one is interested in some Keihin Quad carbs, My classified can be found here.
Keihin Quad 36mm carbs

How did you sort out the fuel setup for the carbies? Because originaly they are gravity fed.

I would say making a manifold from scratch would be better then a DCOE manifold. You still have to do the same fabrication and your only sticking the carbies further away from the head and you may run out of room?

A facet pump takes care of the fuel side of things, it gives about 6psi of pressure with no dramas. I reckon you could use the original fuel pump. We couldn't because our engine mount modification for the A14 got in the way.

Benny, just hoping to lower my lap times with the new suspension and tyre package this year, any hopes of catching Chris at this stage would be slightly deluded I think. Maybe once I get the A15 up and running I might be able to get within a stones throw of him.
How's your beast coming along, will it be amongst it this year?

Cheers Aidan.

Nah not really, just involved an old dyno and an exhaust gas analyser, we just drilled out the main jet and packed up the needles with washers until we got the right a/f ratio. Although i'm thinking of drilling out the pilot jets a smidge to get rid of a small flutter just as the throttle is cracked open.

sounds good. What model bike are they from again? I know ive seen it around somewhere but interested. Are they suited to more top end power?

I think the 'K' in CVK is something Kawasaki did, which leads me to believe that these are off a zzr1100 or something. I was told that these were the same as used in the aussie racing cars, you know those tiny little holden/ford look-alikes.

As for top end power, the way i look at it, if they can flow enough air and fuel to make 160 hp on a motorbike, they should be good enough for that on any engine, although the kawasaki motor would obviously be a bit more efficient than an A-series. The motor i'm running them on now is a 1469cc A14 has had a mild port tidy up and a cam that is happier between 3 and 7 thousand rpm, and it pulls all the way to the top. We saw about 90-95 rwhp on an old dyno, but not too sure of it's accuracy.

I'm going to run these on a 1600cc A15 which is going to be built over the course of the next 6 months, which will have bigger valves, ports, cam profile and a higher red line. I'll see how they go for interests sake and then probably go for quad 45mm throttle bodies with fuel injection.

wow thats decent, when you got them did you fit them up etc etc then try start and it ran?
didnt flood or not have enough petty to run ? By that i mean did you have to do anything to get them just to run before you could start tuning?

Very impressive

Yeah it fired up straight away when we first put them on, just didn't have enough fuel in the top end. The idle cicuit is untouched still, but due to a small flutter and some backfiring through the intake when the throttle is at 1/8th I'm going to drill out the pilot jet which feeds the low speed circuit. These carbs are so simple and there's heaps of info on the net from motorbike websites. I guess the same principles apply from SU's and any of the larger CV carbies. And at 200 bucks + manifold fabricating, it worked out a hell of a lot cheaper than some webers or dellortos.

I used to run some 36 or 38mm quad cv carbs and worked quite well with longer equal length runners, I had no flutter or flat spots on a 79mm bore A15. Problem was that I cracked the 1st and second bores from revving to 8-9k often. It made no power up there but it was fun to see the tacho go that far.

Ill never go for such a big bore anymore prefer to try an 85mm offset stroke with 77.5mm bores and similar quad carbs again.
Nothing like the little suckers.

The sound that this engine makes as it comes up to the rev limiter tells us one important thing. It's getting enough air & it's tuned right. It's a lovely song that needs to be heard to be appreciated, so next time Aiden's out at the track, see if you can get along & cheer him on.
I know I do whenever I can.
