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...
Great video. Really helpful and visually detailed. I probably will do this on my 2021 Trail125 by this summer. And thank you for showing the wideband sensor result, because of that, I changed the fuel injector order from 170 down to pcx155 on my Yuminashi's shopping list. I hope it will make my Trail run less richer. What do you think?
I think the 150cc is still too rich with the stock intake and exhaust. I'm still tuning and waiting for some warmer weather to do some extended riding and get the engine hotter, so I'm not ready to share a recommendation just yet.
Great video! I used to have a 1975 Honda XR 75 and had to replace the timing chain. The process here was a bit more complicated but overall very similar process. On the XR 75 the engine had to be removed and crankcase needed to be split to get new timing chain on. I have a 2024 CT 125A now and currently dont plan on modifying it. ❤
The installation appeared straightforward until it came to filing the rings, which I wouldn't be capable of handling. I assumed it would be a simple install-and-ride process. Moreover, riding at high speeds, such as 60 mph, on a small bike seems perilous without larger tires. I appreciate the power for hill climbing, similar to the CT110 that featured a sub-transmission, allowing it to traverse any terrain.
Very rare to find an interesting video these days. Don't know how people can be so boring and think they are the greatest. Don't know why I'm watching this video, as this is something I did more than once, a sign i enjoyed the video. You're absolutely right about going higher on cc brings more issues. I installed a 181, and guess what? Installed the original 125cc back and never again had another issue with it. Kept the piggyback ecu for the high RPM camshaft though. By the looks of it, you're also having problems with yours. I took mine to the dyno, 13hp. And I still brought it back to original cc due to the constant issues. The worst of all was stock bikes not only keeping up with mine, but also overtaking me. That was not funny.
I find this interesting, i would have changed the gear ratio before the engine for going on the road, it also defeats why they call it a trail 125 bike. If anything i would have shorten the bikes gear ratio for acceration and torque by the rear aftermarket sproket to just to closly match the 1977 honda ct 125 trail bike with a 53 teath rear sproket for trails, back roads, and neighborhood riding to grocery stores. But i also know everyone has there own purpose for it. I know this because find parts parts for the '77 is like fishing for needles in hay stacks. I had to learn every inch of my grandfathers bike to fix it. its got a top speed of 30 mph, it was imported by japan only in '77 to america. And it was mostly bought by the goverment / forest service and advertised to the public for a farm bike.
I did some research on swapping sprockets and with the ABS, it seems a mismatch between the front wheel sensed speed (ABS tone ring) and the rear wheel sensed speed (via engine RPM) causes an ABS error and the light to kick on and disable the system. This bike is for a new rider, so I wanted to keep ABS intact.
i just subscribed to you now i need to go back and watch your videos so i know what you did wrong and did to fix it. so i can do it right the first time. I HOPE. lol thanks i wish i had found your channel a couple months ago.

@leeinwis I replaced the cam because you have it out anyway, you will also need to increase the amount of fuel: th-cam.com/video/EeXsm-Qf62E/w-d-xo.html
Big bore kit is a good way to go. Just need a little adjustment in the fuel mixture. The bigger cam is a bad idea. With that cam your going to loose all of the increased torque the big bore kit gives you. A big cam is fine for a street bike. On a trail bike big cams suck.

Hi, came over this video because I own a couple of Skyteam / Honda Dax 50cc and both are upgraded, one to 140cc and the other to a racing z155cc. That exhaust pipe inner diameter is 16mm on the Honda Trail 125cc - That is too tight, I have 28mm on anything greater or equal => 125cc or the airflow will suffer and the HEAT increase... Maybe a little tip, maybe increase the outlet pipe diameter!? Cool bike, but my Daxes rules... Cheers :)
@@ozarkgarage I see. I did it for the heat, so the engine / outlet isn't gonne reach too high temp. I chopped the exhausts muffler part and welded on the 28mm pipe - almost same noise, more airflow and less heat! But like I said, an upgrade from moped 50cc to 140 and 155z engine = needs more air.
53mm its batter to me. standert valve cylinder head. potring in ex batter. just replace cdi racing or ecu. but bercareful some damage coming. timing chain. tensioner roller set pushrod tensioner. can damage and hit gearbox. you engine can totally broke.
probably more like 1 or 2 HP at best...You figure they only gained 5 MPH absolutely balls to the wall not in the RPM comfort zone in absolutely ideal conditions so I totally agree with you.
I'm less concerned with top speed as much as speed loss going up hills. On 2-lane back roads, dropping to 45-46 mph on a hill is not only inconvenient, but also unsafe. If we can get a 15% increase going up hills (displacement was increased by 14.4%), that will be 52-53, which is a lot more reasonable on a 55mph back road. In the next vid I will show some before/after footage and see if we achieve the desired results!
I don't know what was the expected power (probably about 14% more, just like the displacement) but do you know this would only increase the top speed of 4.5% ? This is definitively useless, in my opinion.
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.
Why not just buy a more powerful "adventure" bike that can keep up with highway traffic? Same situation as a motorized bicycle guy wanting to go 50mph, just buy a used Trail 90.
I don't understand why people buy these then scream how can't go on highway and proceed do all kinds stupid expensive mods . Yeah these where never designed go at highway . Get the right tool for the job.

Hello how is the engine breaking with the new piston?
Interesting and a lot of fun but not for the average rider. Solution? buy an XT225 or a CRF300.
Could you measure the OE ring gap and use that as a base line?
Gap increases with the bore size so using the OE ring gap would be too small for a larger piston.
@@ozarkgarage Hence baseline.
Idk why honda wont sell the Xadv 750 in America. It's a total shame
Never heard of it before, so I had to look it up. Pretty interesting.
i might be wrong but why did the cylinder say 125cc on the big bore?
Either they use the same cylinder casting for all of them, or the marking keeps it "stealthy" for places where the mod is illegal.
Unless it fixes some gremlin like oil consumption; I dont get the point of punching a bore over a few thou to gain 5hp.
probably more like 1 or 2 HP at best...You figure they only gained 5 MPH absolutely balls to the wall not in the RPM comfort zone in absolutely ideal conditions so I totally agree with you.
