It depends on the engine power, torque and various other engine parameters

home desgning an engine is a colossal waste of time, unless you're just interested in doing that for the sake of engineering. It wont make much power or be reliable without a lot of machine work and experientation. Trying to slap together a crankshaft out of scrap material without a lot of machine lathe exerience is going to be an excercise in futility. Crankshafts are extremely sensitive to balance, and straightness.

You can buy a Honda BX200 clone in the US for $100, and a centrifugal clutch that fits it for $30. that's what is commonly used in homemade gokarts. Building something bigger and more like a UTV is definitely do able with off the shelf components and a homemade frame/body. Heck a 6hp BX200 UTV is probably do-able (with a better clutch) it just wont have a very high top speed. Lots of early low CC UTV's were <20HP and stiill manage to do 30+ MPH.

projektowanie silnika w domu to kolosalna strata czasu, chyba że interesuje cię robienie tego dla samej inżynierii. Nie da ci to dużej mocy ani nie będzie niezawodne bez dużej ilości pracy maszynowej i doświadczenia. Próba sklecenia wału korbowego ze złomu bez dużego doświadczenia w obsłudze tokarki będzie ćwiczeniem daremnym. Wały korbowe są niezwykle wrażliwe na równowagę i prostoliniowość.

Możesz kupić klon Hondy BX200 w USA za 100 dolarów, a sprzęgło odśrodkowe, które do niego pasuje, za 30 dolarów. To jest to, co jest powszechnie stosowane w domowych gokartach. Zbudowanie czegoś większego i bardziej przypominającego UTV jest zdecydowanie możliwe przy użyciu gotowych komponentów i domowej ramy/nadwozie. Cholera, UTV BX200 o mocy 6 KM jest prawdopodobnie wykonalne (z lepszym sprzęgłem), po prostu nie będzie miało bardzo wysokiej prędkości maksymalnej. Wiele wczesnych UTV o niskim CC miało <20 KM i nadal udaje im się osiągnąć 30+ MPH.

We are talking about a large engine here because it is over 600 cm3 and it could be even 1400 cm3 I don't know I didn't measure it but I doubt it would be an engine larger than 1000 cm3 in the case of the 1.0 engine I am counting on about 25 horsepower And if it is 1400 Well then I am counting on 35 but that's how I build the engine myself because I love DIY Besides I have quite limited resources and in general I gave myself such a challenge to build it from scrap and the crankshaft will be made by stabbing and welding it will be such a connection We'll see if it works

Nie można zbudować niezawodnego silnika spalinowego ze złomu i rur. Udowodnij, że możesz to zrobić, oglądając film z budowy i pracy silnika.

i know how engine works but i building my own two-stroke diesel engine

I am interested in how your DIY UTV is going. Any update? I have played around with building go karts but we always buy the engines off the shelf. Wondering how this endeavor worked out.

      If anyone is looking for the cheapest UTV, with dump bed, winch, roof and windshield, I just noticed that lowes has the axis 500/ hisun UTV on sale for 4500 (at least in my area) They are $4500. ($9000 original). I have one - they have some issues, but nothing catastrophic. My biggest complaint is that it is under powered. Also the winch failed. They are still selling an extended warranty - which I would take, just in case. My guess is lowes wants them gone.

      So I'm interested in a side by side of some sort.
      Not sure what make/model to even look at.
       
      I would plan on riding on trails with very rough rocky terrain and plenty of mud. Maybe sand once in a long while. I like LOTS of power and drive fast, but also like a trail that is a challenge to get through. I think 4x4 would be a must. I like the idea of a supercharged engine, but I have never owned one, and would be a little concerned about long term reliability or expensive difficult engine repairs. If anyone knows quads, my favorite was the 2008 Polaris Outlaw 525 IRS. For dirt bikes, I raced a 2008 KTM 450 SX-F. So that gives you an idea of what type of off road stuff I liked.
      I don't like "utility quads" or "trail bikes". And likewise, I dont want a turd UTV. I want something that looks awesome and performs awesome. 2 seater with some cargo capacity at the minimum.
       
       
      Thoughts?

      Hey everyone – my name is Adam and I’m doing some market research to better understand the ATV / UTV community. I'm especially interested in hearing about:
      What you use your vehicle for (work, play, etc.)
      What you love about it
      What frustrates you
      What the overall experience of riding has been like
      If you're open to hopping on a casual 30-minute Zoom or phone call sometime this week or next, I’ll send you a $100 gift card as a thank-you.
      No sales, no pitches—just listening and learning. I'd also just ask that you send over a photo of you and your side-by-side in action (nothing formal—trail pics or selfies are totally fine!).
      If you're down to chat, drop a comment or DM me and we’ll find a time that works. Would really appreciate the chance to learn from you 🙏
      Thanks!
      – Adam
