I will be towing a lightweight trailer for touring the USA.
Zenoha G43L is this engine adaptable for an AZ build?

That HP is rated at 11,000 rpm. The clutch will only go to 7000 rpm, so you're loosing some of that power.
You have to fabricate all the mounting system too. You'd be better off with something like this, https://www.bicycle-engines.com/4-stroke-engine-kits/ but not from this company in particular.

This is NOT the Zenoah 343; it's a Chinese engine.
I've used it many years ago, in F/D and midframe chain drive.
It uses the 76mm clutch, common to most 35cc+ engines used as gopeds, garden equipment, R/C toys, etc.
If using the 5-7000 rpm clutches, you'll sound like a modified clutch-slipping moped.
I adapted 1800rpm pocket bike clutches to this high-winding engine.
The SBP pipe worked well with this engine, even the standard China Girl stock pipe.
The 460 has power galore.

I understand all that, I like that motor too. But, Midwest Rider wants to tour and that little motor screaming all the time isn't going to make it pleasant.

The 460 can be a mild-mannered powerplant.
It is loud with the canister muffler, but extremely quiet with the SBP pipe.
So quiet that I swear I could hear the piston ring scraping the cylinder at idle speed.
It's docile too.
With low rpm springs, it'll putter around in stop-and-go traffic.
Torque comes on smoothly.
However, when you yank the throttle, hang on tight!
And I mean that literally.
You might slide backwards, right off your seat!
I miss that engine.
Even though my Tanaka 47R engines have less power than the CY460,
they are more dependable.

Another plus I liked about the 460 is it's light weight and compact.
You could actually carry a spare engine in your back pack.
However, it might not be best suited to tow.
Any mild-mannered 2-stroke or 4-stroke could tow.
This is an engine that can putter around.
However, but power CAN come on like nitrous oxide!

The 7k and 5.7k clutches lock at those speeds. That's not their max rpms lol.

Those clutches ENGAGE at that speed. They remain engaged throughout the 11,000-18000+ rpm range.
That's why I installed a clutch which hooked up off idle.
The 460 idled at 1300-1500rpm.
The clutch on my 460 engine grabbed at 1800rpm.
Using clutches which engage at 5-7000rpm won't work well on the street.
I believe Staton sells low rpm springs from a GXH50 engine.
Those worked for the 460.

Ya, I thought about that after I posted, what do you think the rpm will be when the clutch starts to kick in?

7,000rpm or 5,000rpm or 2500rpm or 1800rpm.
Depending which clutch springs you use.
Staton once sent me the wrong springs, and my bike launched like a moped.
