Making The Worlds Fastest 150cc 4T Barrel
Making a barrel from scratch for my race bike. Design, printed and cast.
This barrel will bolt on to a FXR 150 bottom end and allow water cooling and allow the use of a bigger piston running in a plated cylinder.

Amazing work man, congratulations! 👏🏼 Question. What investment material did you use? Just regular plaster? Thanks
Might be good but for your sound effects/music blaring through my speaker
Just want to say this whole series has been rad to watch. Can I ask what you use for a mill and lathe? They seem like they would fit my needs well!
I've a different opinion on going faster and safe. Go to the nearest race track and get some track time. Most tracks have teacher(s). Get the coaching. Next would be to get better suspensions. My preference is YSS. Also get proper tyres. Next is to get your ecu reflashed on dyno! You should get race exhaust full system, race velocity stacks, and race filers before reflashing your ecu. You may need to get stronger clutch springs to handle the increased engine power.
Orange glowing molten aluminum looks like fluorescent neon Cheetos...
@elburropeligroso4689 Hahaha not quite as tasty though 😅
I would suggest that you raise your melt temp and your mold temp about 38C hotter than you have it.
@@hunnybunnysheavymetalmusic6542 I did end up upping the temp after this video, It definitely helped.
Yeh.... Interrupted pours are definitely bad...
@@hunnybunnysheavymetalmusic6542 😆 Yep, inclusions everywhere haha
It is sounds like something
The reason your casting is less good the closer it gets to the top is because of the pressure dropping as the amount of aluminum on top applying pressure decreases. I've noticed that increasing the height of the risers to increase heights of the aluminum column helps with quality.
how bout you try jewellery style investment mould making? you coat the pattern with thin investment, let it dry, add more, let it dry, then do a few thick layers, some with sand, then put the whole thing in loose sand.
@felderup Hmmm that's a cool way of doing it, I may try it in the future.
@@TheMotorcycleForge a lot of youtubers almost do it, they coat foam patterns for lost foam in random kinds of plaster, sometimes drywall compound. the jewellery method holds together better, has to, cause you melt out the pattern. some go crazy with plant fibres as reinforcement, they're not backed by sand, but an engine casting in sand would be fine without.
You really should be doign this with ceramic shell casting, not unvacuumed block moulds :)
@noviceartisan I had plenty of investment left over from casting the head, so it was easier to just use that and I couldn't do ceramic shell casting on the head due to the water jacket, it would have been impossible to remove the shell from somewhere you can't see or touch.
No way to add a vacuum port to the base so you could whack a shop vac and massively help the casting flow? I've made my own vacuum system up, and experimented a bit to add vacuum to things to make them work with investment :)
@noviceartisan I did make a vacuum chamber and got a vacuum pump and tried it once but had a blowout due to insufficient mold thickness, so I decided just to do it gravity casting for now. I will have another go at vacuum casting in the future.
Bloody Kiwis, clever little basstards... and persistent! Listen mate, have you covered how you calculate for shrinkage in any of your previous videos? I have watched all of them but don't recall much on the topic. btw, can you make 10 videos a week, they're ******* rippers!
@robertoburromiapanino2659 haaha very high praise, much appreciated. Yeah so shrinkage in Alu is supposed to be around 3% so I just made the wall thickness to accommodate that. I tried casting 103% size but it doesn't shrink like that as the distance between parts doesn't change, only the wall thickness does. So casting 100% size yielded more accurate castings. As far as feeders on top of the mold, you want at least the same volume as the rest of the casting. Hope this helps, and I'll try but 10 week might be a stretch 😅
@@TheMotorcycleForge Thanks mate, much appreciated.
Love this. Arrc spec ub150 makes around 27hp. 22mm intake valves 32mm throttle body
@mgck6822 very impressive, my current goal is 30hp at the wheel and see where we go from there.
@TheMotorcycleForge not sure what's your plans for the bottom end or if ur race spec allows non factory fitted, the gsxr150 fi or raider 150fi crankshaft and rod is kinda updated version of the fxr. Smaller lighter crank, shorter rod at 98mm, smaller piston pin 15mm. I have a feeling it will drop in
@mgck6822 I have designed most of the engine components to accept R6 parts so I will be making a billet crank from scratch to suit a R6 rod but also fit in the fxr crank cases.
Theres nothing like trying to save some dough, fuckin up, and ending up spending twice as much. At least I'm not the only one lmao
@@georqedubyakush6066 Yep haha, can't give up!
6:11 Whats the stuff you poured on top?
@@beachboardfan9544 Hot topping to keep the feeders molten till last, it helps prevent shrinkage
@@TheMotorcycleForge Whats it made of?
@@beachboardfan9544 I have no clue, it may be something like thermite
Any plans on doing any 2 stroke stuff im a 2 stroke person
@GaryJonrd I plan to build a rotary/Wankel race engine which is pretty much a two stroke 😅. I have a dt175 which I have tuned and will definitely be doing other two stroke projects in the future.
This reminds me of when 2StrokeStuffing made his own barrels...
@ashesman1 Very high praise, and he does some awesome work 👌
Sir you one die hard engineer “bravo”
Great video mate, love to see someone making videos on things they are actually passionate about 👍👍
Utmost respect for your work, most people are pretty stoked if they can rebuild an engine (me included)......but making one 😮
@nickrider5220 Cheers Nick, it's definitely a process and enjoying all the learning.
"On tonight's episode, I pet my Cat" Ok, subbed, notifications on!
@bo-dine7971 Hahaha awesome 👌
Do you want to make watercooled for fx150. Why dont u use satria fu fi/ raider fi. Already have coolant hole.
@alifhakimi2326 Because I would still need to make a new barrel as the valves and piston would be too big, and it's a lot more fun to make it myself. 😁
Love it !!
@@tjaynef Cheers Rick!
👍🙂
Plane or needle bearing would be a lot better for durability and robustness 4:00
@My_Gaming_Mind Unfortunately, the main bearings will have to stay as ball bearings. It would require making new crank cases which I'm not quite up to doing just yet. The big end of the conrod will be a white metal/ plain bearing.
Well done, the 3rd try went very well.
@emanggitulah4319 Yes, I am very pleased to be onto machining so soon.
@TheMotorcycleForge just subbed. Excited to see the journey... Loved the cardboard aided design LOL
@@emanggitulah4319 Thanks, much appreciated 👍
How about Densamet for the crank counterweights? You can machine steel ones and then add densamet plugs to the steel. We used to do this for Brabus crankshafts as well as Ducati World Superbike cranks that we used ro make.
@YAMR1M oooh yeah that's a great idea. I will look into that. Cheers Logan
I'm familiar with that friend of yours in Australia 😅 Glad to see you sticking with the project mate, it's coming along great
@dan5her yep, it's a small world ahha. Cheers man.
Legal CC 😂😂
@@corey_nz Ikr 😆
What is the red dust you put on the hot mould?
@Kingcactus20000 It's called hot topping, it keeps the feeders molten to help minimize shrinkage.
@@TheMotorcycleForge Awesome pour. That hot topping is like a thermite right? But you do see a big difference with or without hot topping? Great work
@JermainFishwick Thanks man, yeah I think it's some type of thermite, and it actually makes a massive difference.
@@TheMotorcycleForge Thanks for the reply! Take care
Awesome job mate, can't wait to hear it run
great work well done, looking forward to the next episode Roy NZ
This is great what a journey. Can't wait to hear that engine fire
Bloody brilliant. 👍
Woo Hoo, that was a great Episode. Awesome progress!!! 😎
Hello, could I instal pwk in my scooter consider its 150 cc Chinese?
Great video! Very quick but very thorough
Hi logan .
If you advance the pickup coil on a small cc bike do you get more power and do you need to give it more gas and where like tuning in catby
@crossbow_reveiw Be very careful with the pickup coil as if you add too much advance, you will destroy the engine. You will need a way of testing alterations to make sure it isn't knocking.
What is the powder that you put on the aluminium after the pour
@petersilva4242 It's called hot topping, The reaction keeps the feeders molten to help with shrinkage.
Great vid. Timing was perfect, as this is a job on my sv650.. 🤣🤣
Does the concave stick Outwards or in towards the bike?
@desertrider325 I think it was inwards but it was quite a while ago so not 100%
So i have yamaha aerox 2 stroke. After switch to 70 cc i put after market exusost and built the transsmision,and up jet the carburetor so now its start but after 2 minuts of idling its shot off. I played with the fuelscrew if i add more air the idle is hang on a litl but on that setings when i blip the throtle its back right on the idling but after that go below idle and its dies. And today i was riding it for like 5-7 minuts it was going good but when i stop the idle was incrise and its was idling like 4 stroke scooter then whants to die. What your suggestions on that ??
@darkogligorov606 I would say, you need to rejet it and see how you go. Maybe to big on pilot jet.

Nice ,do u have cad model of honda rs125 nx4 frame, swing arm, fairing and other other parts?
@vijaykorvekar1009 Not a cad model, unfortunately, that would take me quite a while to draw up. I have two physical nx4 chassis in the garage, though 😅
@TheMotorcycleForge is there any way you cab 3d scan it ,with good quality
@vijaykorvekar1009 I currently don't have a 3d scanner, but it's definitely on my list of things to get.
@@TheMotorcycleForgecan you 3d scan your honda rs125nx4 fairing ?,do you have Instagram or Facebook? I would like to check out your honda rs125 nx4
@TheMotorcycleForge I am not the rich guy ,but I'll pay for 3d scan of the honda rs125 nx4
Nice work man subbed to see future progress
Should really withdraw the reamer under power.
I watched a video on this job, he said to be careful when inserting the seal’s as one of them has a lip on one end and need’s to be fitted that way up
@@StoicriderX Most calipers are the same as this one where the seals can go either way up. But I'm sure some odd ball bikes have asymmetrical seals. You will soon know when you get the old ones out, give em a good clean and inspect.
I would raise the intake ports as much as possible. Even if it ment modifying the valve cover to allow the intake runner to run beside the valve springs. Also raise the exhaust ports to around 20-25 mm of the valve cover flange. Raise the spring floor slightly . Finding valves that much longer possibly 12- 20 mm longer. Maybe find valves that are much longer. Possibly find larger valves with the same stem diameter. Grind the head to size or possibly have the stems ground to size as well. Carefully and slowly milling the lock, slowly creeping up to the size of the grooves required for the locks and retainers. Maybe a manufacturer will make a small batch of valves for you may as well go up in size a couple mm while at it. Have valves produce that are 3-6 mm over size before finish grinding to size . To allow for larger valves. A intake that has a carburetor boot bolting on the valve cover would have to produce some power. The flow bench should show major improvement. Making slight changes to a stock head isn't really going to do it. And I'd rather have the iron sleeve, plates cylinders are too fragile in my opinion. I could really get into a project like this. I was working on a scooter project trying to get the most from a 50/81cc engine. I ported the head too much, bought another, ported the roof of the intake only, bored the throat out about .020" gave it as much of a high port as possible. Getting more like 12-15 mm would be better. Used a high compression piston, skimmed the head slightly. Unshrouded the valves. I wanted to remove more like . 030" -.040" from the head or . 010" - .020" of that from the cylinder would be better get more quench. Have the piston at the top of the cylinder. It made decent power for what it was. I also went with over size valves. The valves are . 3mm over stock size. They could be 1mm larger. Having the spring pocket coming out into the intake port will hurt performance slightly! 😂, You learn from mistakes. I could epoxy a spring shim in place or buy another head and leave the port . 020" smaller! ✌️ Can't wait to see what's next!
@jamest.5001 The intake ports are as high as practical for packaging, @45°. The valves are much bigger than stock size +5mm and they are titanium so you can't grind them as they are coated. I do love a good project. Cheers Logan
