I like to fabricate, modify, restore and drive interesting projects. Everything from a Lotus 7/Caterham clone to a Chevy Tracker turned into a street-legal UTV to a vintage Harley-Davidson. Follow along with the adventure!
I don't watch videos about bike nor even subscribe. However, yours is super. I love your video so much. And you explained things very well. Keep it up bro!❤
Acrylic Enamel hardeners are what you want, the majic tractor paint catalyst is just a rebranded acrylic enamel hardener. Do not use urethane hardeners because those hardeners are designed to work with polyurethane and acrylic urethane, if you mix urethane hardener with alkyd enamel, the paint with turn into a substance that looks like mucusy boogers.... ask me how I know 😊
Another benefit of this jack compared to a hi-lift is that it is significantly safer and easier to control. Using either style of jack can be dangerous, but this is a much better option.
I've not heard of anyone using EVANS cooling waterless radiator fluid to replace stock fluid in a motorcycle. But I know Jay Leno swears by it for his vehicles. 375 boiling temp no vapor non-boil over and stops corrosion of water pump. Might be something for this Honda Trail if it is running hotter. $50 on Amazon.
Trailers are funny. Always could use bigger or wider or lower or or or.....been think about a deck over setup but I really like my 16 ft heavy trailer, its 83.25 wide 2 foot dovetail. Its 5" over 6" channel and 2k lbs even, as said heavy. Ur setup must be a feather, ever weigh it?
Personally having worked on and run the Z155 Zongshen motor, which is a similar design of engine, I would start with porting the cylinder head as it is free BHP (OK a top end gasket set) and match the ports to the gaskets and smooth out the ports. Next up I would either get a slotted cam sprocket, which is cheap enough or just slot the stock one and back the cam timing of to move the power a bit higher in the rev range. These things don't rev that high anyway with peak power at about 9000rpm and slotting the cam sprocket lifts peak power to about 9250rpm but helps let the engine hold onto the power for longer. My Z155 on the dyno is 14.6bhp and in stock trim was 13.2bhp. But it is not the peak power gain which is important as 1.4bhp is not a massive gain, but where it shows the most is at 11,000 rpm where the stock engine was 10.5 bhp and after tuning it was 14 bhp so it is a 3.5bhp gain over stock. If you need more power still then I would go for the 143cc big bore kit. BUT regardless I would still suggest running an oil cooler as these engines don't have the best design for keeping them cool and the bottom end is still close to the original 50cc motor and these get hot and heat will kill power. The oil cooler just adds a bit of security that it will not overheat or increase heat related wear when using it on trails.
the biggest restriction is the exhaust.. just look how small is the pipe. with a bigger exhaust, not necessary louder,you will se huge great improvment 😊
If the fuel is higher in the float bowl, it is higher in the emulsion tube. If it is higher in the emulsion tube, more fuel will pull through the venturi making the mixture richer. The opposite is also true.
My first time seeing your channel and that was a wonderful video. I have a 2024 Honda XRM 125 in the Philippines and that extra power sounds wonderful. How did it affect your fuel economy? I am getting 65 km/litre here which is 153 mpg. And I ride her as fast/hard as I can most of the time.
I honestly don't think it has changed that much. We put ~90 miles on it between fills and it takes around a gallon +/- so its still good enough for us.
This sounds great BUT being an old geezer with arthritis- does this require a TON of power to utilize the crank? I have a 67 IH Scout to use this deal on- Will it be ok for me? AND I can weld but only have a 110 V Lincoln that I can use.
No, it doesn't take a ton of power to crank. You also can replace the crank with a socket so you can use a ratchet and then use whatever length ratchet you want.
I wonder on how much the cylinder temp change after the BBK was install , I'm thinking of getting one for my grom and i personally dont like the look of the after market oil cooler .
what's wrong with your honda is that it only got small intake valve ideal only for good fuel consumption and not for high speed. the multi hole injector is for bigger valves or 125 cc chinese motorcycle. a stock 125 cc chinese motorcycle are 27mm intake valve and 24 mm exhaust. your honda is tiny 22 mm intake valve.
I watched Part 1 and just finished watching Part 2 of the video series explaining this experiment to get more power for your Honda Trail. I found it interesting and educational. As a relatively affordable upgrade for the Honda Trail 125 (now 143cc), it's an appealing solution. That said, it seems the overall limits of the Honda Trail continue to manifest. As a "do it all" bike, the demands of highway riding or heavy loads of cargo (or rider) continue to push the envelope of what the bike's engine can accomplish. Or, put another way, the engine's power output remains the "limiting factor". Thanks for sharing your upgrade adventure. 🙂
One thing missing on the hi-lift jack, the ‘winter feet’ to keep it from sliding around when you don’t want.. I used 3/8 by 1 1/4 bolts with nuts on the bottom. The thread locked into the ground, End of slide-out..
What a lovely little engine to work on. That's another advantage of choosing a smaller machine, as well as great economy and just the lower weight when you need to push around or manhandle. I had a 90, super little sporty model (SS90, 90SS?) in the 70s and it was the most fun bike I've ever owned. Great video, thanks for posting.
All the engine weight is down low because of the cylinder lying almost flat, the triple clamp and frame neck being low, and the tank under the seat. The bike feels lighter in terms of balance than what the scale says.
@@RetroYamaha I'm guessing they use the same casting for all cylinders regardless of bore size. Either that or to keep the mod low key for places where it may not be legal...
The ct125 dosent need something to make it go faster, it goes at the correct speed to see life and beauty and humanity unfold in an enjoyable way. The problem is the worlds going to fast and it’s everybody’s job to recognize this and slow it down. The ct125 is a tool to help you recognize this and recalibrate your life. Don’t screw the tool up by making it fit in with the broken world.
There’s also no reason NOT to make it go faster, the whole point in modifying something is to fit it for your wants and needs. What’s perfect for one person might need a little tweak for another and be awful for another, no reason to shame people for that
