Update on jetting. There is a whole lot of garbage out there, mostly on American forums. The gist of it it's that you have to have mikuni , and a dynojet stage x kit.
Reading between the lines it does seem there is more expertise out there on mikunis and available jets.
On top of this you have Both types with single and twin butterflies, and also with single and twin main jets (or primary and secondary jets). What this does mean is that the jetting for twin main jets has no bearing on required jetting for singles, and there is very little out there on single jet keihin settings....
Currently I have 35 Pilots, which seem to be similar to others are using, 125 main jet, and probably some mongrel needle which looks nicely tapered, and has 4 settings (now on its highest).
The only issue I have is the idle fuel screw on one of them is seized and split, so it'll need drilling and extracting - we'll see how that goes...
So am I going to persevere wither the "rubbish" Keiheins? You bet, my experience with su's, use of the lambda, and if I need to I can stick it on the rollers should make it doable.
All the best,
Huw

Quick update on this. The carbs are fixed, with covers painted black. The engine is having to come out so I can weld behind the cross brace behind the headers. I'm planning to take advantage of this to paint the frame. however, this means I need to finish welding the mudguard brackets, lugs for brake pipes, and the stainless rack off the wife's mgtf...
Pics to come once the engine is out and rear mudguards/bumper is finished.
On another subject, I've started collecting bits for the next one, hopefully will get a front end on eBay, if the price is right and I can organize courier. I've decided to use the controls loom and switches off a kawasaki 400 I bought with the yam turbo, so that should make life easier.
If anyone needs bits for a kawasaki 400 twin let me know - seat, engine, wheels etc
All the best,
Huw

Update on the last update.
The engine is out, I welded up behind the cross braces last night. Prepping frame for paint next.
The wife's rack ( off her mgtf), wouldn't do it, so I bought some more stainless, it's not finished but will. Have to wait until the engines back in now. Also need to fit the handbrake and cables, so this will likely be done before paint.
Piccies soon, promise,
Huw

Serious slab yokes:  Kawasaki 750 hard tail (was rear end ratios) I'm not sure you could class this as progress, I seem to be going backwards.. Now the front wheel is off, and I'm looking for a bigger disc, Huw |

No way, the original axle was welded into the frame, bloody stupid idea! It's bolted in with 4 m10 bolts on each side. I had to post this, one day I'll make a v6 version of this or something like it:  Kawasaki 750 hard tail (was rear end ratios) Sorry, I know it's been here before... Huw |

Now back thinking about this project again. One of the issues is the front disc being too small, originally the kwack was a twin disc, now it only has one, and with a slab front and rear wheel on the front it's not going to be easy to find a bigger disc to fit. (When I say too small, the breaking was poor, and I noticed the pads were actually overhanging the disc - another killer designed in feature by the original builder).
So I'm now thinking around getting a bigger front disc and machining up an adapter to fit it to the (rear) wheel.
Does anyone have any views on this? Even if I have to move the caliper out along the spindle line, as well as out in radius it shouldn't be a problem, I have enough room.
With any luck I could cure the pad overhang as well as improve the brakes?
Huw

Kawasaki gt750 engine in the boot of my car, it's going on the shelf in work for now. When I get time I'll strip it.
