Hi there. A few tips and lessons I've learned while being a youtuber below. All this comes out of a place of positive criticism. You can decide what you want to keep and let go.
You're content is a bit too varied. It's all about your audience. It is much easier to entertain an audience with a single interest than it is to find someone who enjoys printers and bikes, for example. Always ask yourself who your audience is.
I would strongly consider changing the channel name and branding. Your name might have been your awesome gamer tag back in the days, but it is really hard to remember. You want to make it as easy as possible for people to find you. My youtube tag isn't the easiest either, so I'm going to have to walk this same path too! This is a tough task, because most of the nice catchy ones have been taken. Try for a three word channel name, if you can't find a one or two word channel name.
Your content is really rally cool! I have to give it to you. I don't know if this is the case, but it does sound like an example of your content not reaching the correct audience here. With your content you could and should be growing alot faster. Try to get it specifically to bikers and biker forums.
Lastly, thumbnails are everything! You might want to invest some time in learning about good thumbnails, but that's a whole discipline in itself.
I summary, youtube is all about marketing and thumbnails. I'm not going to address content, because your content is already nice! So put your new videos and channel name on your WhatsApp status, Facebook, tiktok, Instagram, tinder, your parents' fridge, and etc etc! Be proud to be a content creator and be proud of your channel!
