    Lmao what prototype looks like a clone block to me so you rigged a side cover with oil pump or filter that is not new some big block clones have this setup nothing new but I have seen others do this on a small block's nothing new here....

    You’re right, the oil filter + pump has been done before, but my setup also has direct oil line that goes straight from the filtered engine oil to connecting rod for direct lubrication instead of relying on the scoop to splash engine oil (the scoop was then removed to reduce impact from the connecting rod with the engine oil) Personally, I have not found existing hardware that could achieve this, which is why we made this new setup prototype. Perhaps it exists already and I just couldn’t find it, which would mean it was a waste of money, but we did learn quite a bit along the way developing this system, so I’d say it was still worth it.

    @@JSRacing-Kartsmith only thing I would do differently is when cutting seats start with 45 like you did and use the coloring I use just a black sharpie marker to see my cut then switch to 60 use color again the do your 30 but do not use color this time so then you will be able to see your 45 angle being the left over color….. I usually make about 3-4 cycles through all cutters 45-60-30-45-60-30 with just barely cutting a 30 angle and cutting the 60 angle deep so I can move my lap line up on my valve face with it being fairly thin line/45 angle on intake side exhaust side oh and also when cutting you always want to finish with 45 very lite tho… so 45/60/30 then lite 45 one rotation like .5 lbs of pressure

    I've looked through a lot of your videos, certainly can't knock you enthusiasm. A couple of notes about GX clone engines, Honda designed the engines to work at 3500rpm for thousands of hours, we as engine developers want more, clone engines are a copy of the honda, the copyright courtcase by Honda meant that some changes had to be made, so the 224/225cc was produced, Ducar produce the best outright budget block that is then passed along to different suppliers ie. Predator, Jcb, and Ducar themselves. Unfortunately there are a number of design flaws, one being internal balancing, a predator 224 has some vibration issues, mount this on a generator or power washer-not really an issue, but on a minbike or go-kart, it can become uncomfortable. Change the piston and rod to performance, well this upsets the balance even more, change the material and things will fall off! The crankase is cast with price in mind, so Honda GX parts will fit, this also means that moving parts are close to each other and the block wall in a 224. There's quite a few Forums that discuss the 224 in great detail, Bob's 4 cycle, DIYgokarts, Predator 224 owners club Facebook, and of course youtube. Single cylinder engines are impossible to completely balance due to the recipricating weight and girating forces, a twin cylinder overcomes this problem, What came be done is try to make the best of it by using a balance factor for recipricating masses, this will effectively balance the engine for a range of around 2000rpm, there are charts on the web denoting what balance factor to use. These charts are for two stroke engines, but that's all we have, so unless a great deal of research is done on the GX engines I would use this as a reference, and I have. The oil pump is not really neccessary, a shelled billet rod is very reliable with the correct ZDDP classified oil, just change the oil frequently. A 26mm venturi adjustable carburetor will suit your needs, it just requires correct jetting for your application, Black66 has a few videos as does Redbeardgarage explaining carb tuning, Check your timing with a digital timing light, you want 32/34degrees, adjust with offset keys for the flywheel. Horse power is another thing that's a bit of a downer, if you put a standard 224 on a dyno it may reach 9 with the governor removed. When aspiring to acheive more power it may be best to think of it as a % improvement, 100% is easily achievable, but will reduce the engines' working life and as you've mentioned you need to spend quite a bit of money to get there. Attending to the engines' factory flaws will get more from it without braking the bank, Porting the head for greater flow reaps big benefits for little financial outlay, boring and jetting the cheap carb again little cost, an aftermarket exhaust, yep another gain, safety-change the flywheel, benefit is on some the ignition timing is already set to 32degrees, all this will still only get you to around 12hp America has really grabbed the GX market and have a wealth of aftermarket performance parts, but also a wealth of knowledge to tap into, I'm in the UK and there really isn't a GX performance formula, we're still two stroke driven with Rotax being the driving force. I machine or buy parts from an importer, it's been the only way to build my little monster, I have no doubt it will blow up, I'm asking too much from what is basically a cheap £150 stationary engine. I have subscribed to you channel, I wish you luck on the entertainment park project and the engine development. Keep posting 🙂

    Good to see DIY work instead of just buying or farming out to a machine shop. Couple of hints, when checking for leaks use brake cleaner fluid or Isopropyl alcohol, this will remove any reisdue as you check, they are also a little less forgiving when checking for leaks. Second, when porting, open up the the inlet port transition angle from the neck to the back of the valve seat area, this gives the air fuel mixture a little swirl help passing the valve opening. There's a number of videos describing this procedure, David Vizard has a long video on port design, he also references another video that goes into the benefits of a widened port. The increase in port size is minimal to keep the velocity, it's the shaping that's important, these increases are only really felt at higher rpm's

    It's actually an amalgamation of parts from various different engines. The case cover with the pump and filter is a custom made part and its no available for purchase at the moment. It works very well though filtering out all the nasties from the engine oil. It allows the engine oil the last much longer and has much more effective lubrication for the crank shaft / connecting rod.

    As soon as you mentioned the crankcase breather, made me think of all the small engines I have ever worked on and non have pcv valaves. Great idea. But you need an inlet and an outlet on the crankcase. That way there is flow threw the case and not just vacuum. But cooling the valave cover to the crankcase by a tube are that same air. Am I wrong? The valave cover has pushrods inside it open to the crankcase. So that air is one and the same.....

  • @JSRacing-Kartsmith
    @JSRacing-Kartsmith2 ай бұрын

    Hi, I later added another tube from the crankcase to the head cover. It's sort of the same air like you said but the pressure build up within the crankcase is always very high, so extra tubes will help alleviate the pressure much better. In practice, you are looking at much quicker engine response and acceleration.

    Great video. One recommendation I have would be to upgrade microphones (or possibly adjust placement). Whenever your voice exceeds a certain decibel it seems to cause a slight static/distortion. This may also be fixable with EQ software. Other than that you were great in your information delivery, and there wasn't a lot of "filler". Definitely subbing to see where this goes.
