4-stroke question

[theguy2024]

I have only done 2 strokes,

my next build is 4 stroke. I’m not familiar though. I was planning on buying this fairly priced 208cc 7HP Power Fist engine and putting it on a bike with a 44t sprocket.

What kinda speeds can you expect with something of this size? How is the torque? I’m worried it’s not gonna exceed like 30km/h. I have a lot of hills in my area.

With a 7 hp engine using a 10\54 on 26" wheels you should be able to do 50 mph on level roads. Even with steep hills you should still be able to an average speed of 30 mph.

Depends on your transfer of power to the rear wheel,
That 200cc 7 hp will go 65 MPH if ya set it up right

I am going to order a torque converter kit from amazon. Is that was you mean by transfer of power?

Get the genuine comet 30 series and some springs to tune it to your preference...
