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. 🙂

High-lift jacks are FAR more usefull than that little low-lift trailer tongue stand you have there. It may be expensive and complex to make, but it will never replace a proper High-Lift. You just lost credibility with that non-sense claim. Sod off.
@brennanmetcalf4 күн бұрын
Have you ever used one by chance? The overall range from 6" to 50" is actually broader than the usual 48" high lift. Yes, you 'only' have 15" of stoke available in that range, but in practical application you burn up nearly half of the high lift jack stroke just getting it into position. The TaulerJack then stores in half the space as your typical farm jack and far easier to use while being much more intuitive for most people.

If you cut the crank handle off at the top bend and weld a socket on the stub of the crank, could you run it with the electric impact I’m sure you’re carrying? And if that works, would you be able to set it under your axle tube and jack the tire off the ground without strapping it to your frame? Even if my hairbrained idea doesn’t work, I like it better than my Hi-Lift for what it will do.
@ozarkgarage12 күн бұрын
You can replace the handle with a nut and use a ratchet and socket to give you clearance in any direction or let you use an extension. Electric power will spin the gears too fast and damage them according to @brennanmetcalf.
@brennanmetcalf4 күн бұрын
You don't want to use an impact on this mechanism. There is a shear pin in the bevel gear on side wind jacks that you will shear off. You can use an electric drill if you want, but then you need to carry an electric drill, batteries, etc. Keep it simple. The best thing I have found to make the handle actually more useful is to retrofit a spark plug socket head to the input shaft. This gives you a 3/8 square AND hex drive. I use a stubby 3/8 ratchet with a folding handle welded to it. If the handle doesn't have to make a complete revolution anymore, the Tauler Jack will fit in even more places a traditional farm jack will not.
