When is a Honda engine not a Honda?

[Old Bob]

You are getting a scrambled version of what happened.

Honda did have a *company copying the the GXH50 and the GX35. It was not authorized and they were dragged into court.

The GXH50 is most certainly a Honda product, made by Honda.
The serial numbers are what start with two letters, the model designation made be up to four.

GXH50s were made both with black and red covers.

The designations for the 50cc are both GXH and GXV to denote the postion they are intended to run.

Yes there are clones of these engines out there, no GXH50 are not made by daihatsu.
This information came directly from Honda.

*Superior copied the GXH50 and GX35 along with copies of Komatsu/Zenoah RC230 and other engines.
The irony of the GX35 copy is that they were selling the copy for $50 MORE than Honda was selling the original.They do not have Honda labels

older hondas

AussieSteve,
Read your reply, and hearing something about Hondas your grew up with brings me to ask you a question: What Honda models did you have in your area? I grew up in Panama and we had Honda C100, C105, C100, Z50 and many others. Of course, Honda engines were either pushrod or OHC units built to go for ever (maybe). These little GHX or whatever engines are 25% of what Honda used to make in materials alone. When you compare the old Honda engines against the HF 89cc and up to 100cc stuff one runs across, the old Z50 engines are still build twice as strong. Any opinons???

There is a difference between the HS/50cc and the GX/Honda 50cc, for one the carbs are different, coil pickups wont interchange. I own both and in 2 years Ive never done squat to the honda except change oil and a new plug. You just get on it and it starts every time. The HS Im always needing to adjust the carb settings and it lacks just enough power vs the honda that you notice the difference when going up the same hill. Im a fan of both and am confident the HS will hold up over time and start easily. Im convinced the Honda is a superior product but being able to buy a HS for a 150$ says alot vs the honda. Depends on your needs or wants both are excellent engines for bicycles. QXA designates the gx50 with a 5/8in shaft, some have tapered shafts and 3/4in shafts.

Darwin,
What sort of shaft does my Hs have? I've never removed the reduction gear box...perhaps I'm stuck with the box?

HS has the straight 5/8 shaft and will work with most gear boxes vendors sell to go on bicycles. Always best to ask and double check before ordering. The honda comes in different configs depending on its application such as pump, gen, mixer etc.

Hi Cris,
I was talking about Honda motorcyle engines, not motorised bike engines.
I had an XR75, an XL175, an Elsinore MT 250 (2-stroke) and a couple of CB750s, at various times. No complaints with any of them. Good reliable machines.

Size of output shaft

Hello Darwin, well if I knew what box you have I could tell you what crankshaft end you have.

IF you have a "Hoot" gear drive it is 15.1 and I can deal with that
.
IF you have a Grube gear drive it is 5/8 with a slightly undersized keyway, I can deal with that.

IF you have a 4g Grube it has a tapered end crank that I know about, but have not seen yet, no adapter available.

If you have a chain-drive "hoot" you have a tapered crank I have not yet seen BUT, we are working in an adapter fro that one as soon as we get our hands on a "Sample" engine.

I now have my RS EH035, so I can begin design on the adapter for it, and can shop them for production.

I hope this helps you.

Mike
