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.

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.

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.

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

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.

That's why I ask
