I'll also add WOW! The new carb is far better than the Dellorto clone, it's a bit choppy on the top end (too lean might be detonating, using mid grade and off my break in mix, can't find the jet collection) but I can fix that rather nicely by using the enrichment lever and then turning the idle up a bit to keep it running.
I can feel the astroglide smoothness of the rpm acceleration, and my powerband is a bit more defined than it was before for some reason. I can also accelerate up hills better than before (could have to do with just comming off break in and the temp outside dropped considerably between tuning earlier and comming home from work at midnight.)
The Dellorto clone of course has a single adjustment which is a main jet, very easy to use but lacks the stock nt carb quality of having a 2nd adjustment range on the needle for idle through mid range. The Cns has an idle jet with a mixture screw to accommodate it, then has the needle setting, and has the main jet for WOT, and has an enrichment setting, which is nothing like a choke since a choke is actually letting less air in per fuel unit while enrichment is letting even more fuel in with the same air and fuel as before. This actually gives me an idea however, the Cns has an extra inlet to the air intake side, it's a barbed tube that is right after the filter. If a person wanted to inject a very light stream of no2 into their motor this would be perfect if dosed correctly while using the enrichment slide.
Anyways, the carb is definitely an improvement over the nt and Dellorto. If somebody wanted to buy one at a reasonable price then look for a pw80 carburetor. It's the exact same thing that places like bikeberry sell as a Cns carb, most places will be selling this type as a Cns for a motorized bike but at a very ridiculously overpriced amount (bikeberry at 80 dollars for carb, throttle and cables.) I can get the pw80 carb at only $15 on ebay, and I know a throttle with 2 cables and a thumb lever isn't worth $65...
If you really needed jets to make the job easy then I suppose you can get them for this carb but I can tell you that solder is pennies and the skill is free, and for 30 bucks you can get a complete kit for tapping threads and such for a 3mm through 7mm. I was able to use them to do this project in about a day between family life. Since I have plenty of jets for 5mm Dellorto it seemed like a better idea to spend 30 dollars and some time to get a full range of adjustment than it would to probably spend twice as much on the same jet size ranges or just as much on new drill bits to solder and re drill a single jet over and over, at least this way I can quickly pull a jet and put the next size in. I can also give up quickly and put a Dellorto clone on the motor if I'm feeling far too impatient or haven't got time to tune, and I still have jets available to work with.
Also the stock jets fit, and stock are cheap enough to I don't mind cutting and soldering if I need to while this specialty jet could yield issues if used too much in the testing phase from repeatedly cutting and soldering.
Well that's about that. Can't say I'm disappointed with the carb, and the small problem was barely a problem since I also ready had the skill and time to finish it, the only tool I needed was the tap set and it even came with drill bits.
Again this is not a grubee style Cns though I think they recently started using this kind, either way 2 of the ports (odd intake tube right after the filter, and the second one that's closest to the filter on the right side, which is an oil injection point for pw80 motors with the appropriate pump. They both need capping off to work nicely otherwise you get too much air at low rpm and high, one both aren't filtered either, so it's a problem.
