38mm billet SmartCarb 2 installed on 2016 KTM 300 XC-W. First ride!

I ordered it back on the 31st of August and just received it today. It was a rough 3 weeks waiting for it, I was excited and impatient. With the crazy state of the world right now, I certainly understand the longer shipping. I've been pretty frustrated with my old leaking 36mm Keihin. Installation was pretty straight forward. Air boot trimming was simple enough, went quickly using a Dremel. I pulled the airboot off and spent 10 mins making the cutout. I watched all the videos on SmartCarb's YouTube channel, so that part was easy to figure out. I'd say the thing that gave me the most headache was attaching the slide to the throttle cable, and that still wasn't that difficult. Holding the washer/spring in place and guiding the cable into the slot on the slide made me worry about loosing my grip on the spring and launching the washer across the yard. Same principal as on the Keihin, but different enough that I'd need to do it a few times to not feel clumsy with it. Definitely bigger and heavier than the Keihin, but no issues making it fit on the bike. It's an impressive bit of billet machining. I used a 90° inline filter and yellow Tygon fuel line. I didn't touch anything, just installed it straight out of the box. It started on the first kick, without the choke. The SmartCarb 2 was $724. $699 w/ $25 shipping. The throttle response is so crisp and so responsive that it had me giggling to ride my bike again. With the old carburetor, there was a difference in the power delivery that coincided with the different parts of the needle and different sized main and pilot jets. Different parts of the throttle twist had different amounts of "hit" or not, depending on what part of the needle it was on. This SmartCarb pulls like a freight train from the first crack of the throttle all the way to the top, and it revs to the moon. I would say the low end is comparable to the old carb, but the middle to the top is waaaay stronger. It reminds me of how hard a built Cummins diesel pulls. Linear power delivery, strong from top to bottom with no unpredictable hit or dead spots anywhere. I'm glad I went with the 38mm version. The transition from low to mid throttle and above is so much different and pulls so much harder, I have to re-adjust the way I ride. Coupled with the super dry, dusty conditions right now, the crisper throttle response kept making the rear tire step out. With the added bonus of it doesn't leak and I never have to deal with needles, main jets, pilot jets or air screws ever again, no matter the temperature or elevation. I can just get on it and ride, with no worries that it's performing at its best. I'm sold and pretty impressed so far. My initial thoughts are that I might want to go a few clicks leaner and raise the idle a bit. But I'll probably run a tank of fuel through it before doing any tuning. The only thing about installing the SC2 that I wonder about is tightening the throttle cable adjuster locknut on top of the SmartCarb. The nut fits down into a recess on the cap and there is no way to get a wrench on it to tighten it. I might take a socket and modify it/grind a notch in it to go over the cable so it can be tightened. My bike is a 2016 KTM 300XC-W. Red PV spring, adjuster flush.

Small channels have to do this. The larger channels get the vp9 codec no matter the resolution they upload at. If your 1080p videos look like pixelated ass, that's why. Upload at AT-LEAST 1440p to get around it. Right click any video on Youtube, then click "stats for nerds". Look at the "codec" line.
