Huasheng 5/8 straight shaft engine clutch options

[ThatOtherGuy]

I'm interested in an engine with as narrow width as possible. I don't like the wide crank sets. I've built a 2 stroke before and that was fine.

I'd like a 4 stroke option but want to keep width to a minimum.

There is a Huasheng that is available with a 5/8 straight shaft and was thinking a standard gocart/mini bike clutch seems like it would work. Such a clutch with the drive gear inside would (if possible) would allow the most compact width as far as I can tell of any option.

Thought I'd ask if anyone here has done that or knows of it being done or knows it could be done.

Any other options that could reduce width?

Remove recoil starter and?

If your talking 4 strokes
Whizzer motorbike 138cc 4t side valve engine is the most compact because it's purpose made to fit in a bicycle frame

But buying a complete Whizzer or building a Whizzer M/B from scratch is gonna be alot more $$$$ than a Huasheng M/B Kit

What about a used/NOS whizzer engine. Could that be had? What are they're HP, reliability and ability to use chain/sprockets?

I take it that the bike in the photos is you're bike. Looks like plenty of HP if you're doing 50mph for my purpose.

History of Whizzer Motorbikes

My Bike is a 2005 NE-5 with auto clutch - I've made performance modifications

Whizzer Motorbike is Belt drive

Buying a whizzer engine? Ebay?

I just learned recently that there are modern made Whizzers. Previous I had thought they were all from the 40's-maybe 60's.

Yeah E bay might have some engines or complete bikes There also still a few guys who will sell an engine
Sadly there's no Whizzer Dealers in USA anymore but parts or bikes can still be found on
E bay, ecrater, Private Parties or Taiwan

There are also Whizzer Like Parts, so you should know.

I bought a non-Whizzer Company belt sheave for my 26inch rim when my home made job cracked twice. Aluminum is not Steel.

It slipped a lot until a year after I had it, I saw that the butt weld on the extruded and bent in a circle steel, had a lump that was not ground down and sanded smooth. Once with Dremel and emery cloth sanded smooth, it grabs very good.

The only thing I have a problem with is centrifugal clutches are not like a cable hand lever type clutch. So it is still such I will leave it this way.

Mini bike clutch for 15inch wheels and a teenager of lighter weight and I never knew centrifugal clutch to slip. Add more weight, even with 20:1 jackshaft reduction, a heavy bike just is not a steep hill climber.

Modern Whizzers and Vintage Whizzer are for sale all the time on e bay
Most sellers want a fortune but sometimes an honest seller will come up on E Bay and sell a Modern Whizzer in good condition or in new condition for $1k - $2k
Poor/Fair condition $500 - $1k

NEW in 1999 WC-1 sold for $1,450 and in 2005 the NE-5 sold for $1,750
2009 the Ambassador sold for $2K

Vintage Whizzer are more expensive but still can be found at reasonable prices

They look like nice bikes saw them going for too much beyond my price range at the moment though.

I'd like to get back to my original question of does anyone know if a mini-bike/go cart clutch would work with the Huashang.

Engine has 5/8" straight shaft with keyway. Clutch is 5/8" bore with keyway.

I don't see how that wouldn't work but have looked online and have seen not one set up like that.

 

[ThatOtherGuy]

That's why I ask

Do you already have the Huasheng? That motor is WEAK.

I ran the 212 as a vertical cylinder for years. I took off the shroud and pull starter because I wanted the exposed cylinder look, also to skinny it up. As I recall it took off 3”, The starter cup was cut down with a notch for a 1ft long rope with a handle on the end to start. Over time the knot on cup side would wear and break and the pull rope would get as short as 8” before replacement. But that cut down starter cup is like a holesaw. Even without teeth it will chew up your leg. Was at a stoplight one day and the driver in the lane next to me said “Do a BURNOUT!!” I obliged, but when the rear wheel moved to the right that holesaw went right into my calf. You can slim it up another 1.5” by just running a belt or chain direct off the crankshaft and putting the clutch on the jackshaft like a whizzer (probably why it was done like that). 212 is still a wide motor, but plenty of power to do 55mph as stock with only basic free mods.

Why don’t you instead tell us the kind of performance you seek. Stuff like power, top speed, ability to be modified later, what kind of wheels/frame you plan to run.

Do you want a motor assisted pedal bike, or a pedal assisted motorbike?

It's been done before, with a bushing to fit 3/4 clutch on. .............Curt
