In a previous video (    • Are 2-Stroke Bicycle Engine Kits wort...   ), I built and tested a 2-stroke bike engine kit. For $120, it turned out to be a great kit! It does require a little bit of upkeep and maintenance. In this video, I put together a 4-stroke bike engine kit and then compare it to the 2-stroke bike engine kit. We test top speed, ease of use, noise, amount of exhaust smoke, and several other things. I purchased the kit from Amazon for $189. I don't normally provide links to the products I test, since I'm not an Amazon partner and my goal isn't to sell products. These kits are also available on many other websites. So, recommend shopping around for a better price.

    Thank you all for suggesting such terrific video ideas, including this one! Here are a couple of links for bike engine kits, but highly recommend shopping around for a better price.

    I’m 13, and my dad is a mechanic, I just kinda wanted to show him that I was interested in working on engines because I ride with him, but don’t know how to fix anything, that 2 stroke kit is coming for me in a couple days.

    It’s a very rare thing for such a big YT channel to read and reply to most comments, I’d like to say thank you for taking the time and trouble to do so.
  • @robertgoss4842
    The 2-stroke and the 4-stroke videos were both excellent, and presented with your customary precision, confidence, and gusto. Looking forward to your next video.

    Lifelong biker here. Loved watching both these vids, shame these engines are illegal for road use in the UK. Top tip for the handlebar grips; when fitting new ones, use hairspray!! The solvent evaporates after half hour, and the gentle adhesive in it will keep the grips on there for life!!

    If every DIY video on YouTube was this detailed (for beginners and intermediate hobbyists) I would never have to do any research lol. Thanks again, Project Farm!

    But the 2stroke is the "Smell" of my youth. You're new to me, I like the detail you give that so many others don't, so I subscribe.
  • @ericshayer
    I simply love the two stroke oil smell. But the centrifugal clutch is a game changer for the 4 stroke
  • @jasonh380
    He has convinced me to buy both a two-stroke and a four stroke this man deserves way more than he has
  • @terranempire725
    Thanks for another great video. I watched both the 2 and 4 stroke videos and enjoyed them. Riding a bike at 37 mph is pretty brave. This has me thinking about building one for myself.
  • I just wanted to say that I had one of the 2 stroke kits and I used this as my only transportation for about a year ( then it got stolen) and there is most definitely a lot of maintenance involved with the 2 stroke and quite a bit of a learning curve with doing that. The most important thing I found was making sure the chain tensioner was properly aligned and tightened. I had a chain break and that was no fun at all. Also having good tires and thick tubes is a must. Lastly I would never recommend buying one of these kits for a young child to ride, the bike is fun to ride and all but just not engineered for those kinds of speeds. I'm a grown man and it took all of my attention not to get killed on mine when riding around in Las Vegas, probably better off that it got stolen because it was just a matter of time.

    Such a great idea, let's call it a motorbike!

    I love your show, I've been with the Home Depot for almost 22 years now. I recommend your show whenever someone has questions on products you've tested. They make a 12v turbo/super charger for around $100. It might be fun to hook that up to your 4 stroke bike motor to see what it does.
  • Love the zip tie spacer trick! Also I appreciate how you keep things fun, scientific, and honest.

    “Don’t use gorilla tape, I want to get this off...”. That is the most accurate description of gorilla tape I’ve heard. That tape is like epoxy. I’ve used to to install a license plate temporarily, and when I wanted to install it with screws, I decided just to keep the gorilla tape it was so clearly adhered to the plastic bumper. It was like that for well over a year. Great video

    lying down and watch this with a cup of hot coffee, wondering this will be my next project during this covid19 lockdown..
  • I just have to say one more time how much I appreciate your videos. I honestly believe you could not do a better job you will be the first person I contribute to on patreon
