Hi, I’m fairly new to Cyclekarts here in the Uk. I am buying a Honda clone engine with a 20 mm output shaft.
I need to buy a torque converter. I can buy a branded one at around £120 or a Chinese clone for about a third of that cost. The clones come as 3/4 “ or 1”.
What does the sizes refer to ? Is it the size of the output shaft on the motor
If it’s the output shaft then I would buy the 3/4” and drill it out to 20 mm
Can anyone advise me ?
Steve

That's the output shaft size...3/4". I didn't know the clones were 20mm...here in usa they're 3/4"

It's the engine ouput shaft diameter. The cvt has a built in keyway that slides onto the output shaft, not sure you can drill that.

Most clone engines have a 3/4" output shaft, you might want to wait and check your engine before getting the TAV



S'all for now!

From everything I have seen over the past 3 years.............don't buy a "clone"!eye rolling smiley
Spend the extra money and get a real Comet!
But make sure you get everything that is compatible with your motor and your build plans.
Shaft size, sprocket size, chain type, etc.

The clones can be hit and miss.
Personally, my experience has been great with the one I have from gopowersports.com for $120.
I've abused the crap out of it for almost 3 yrs and it's smooth and tight as new.

Now, the one I got off ebay new for 53 bucks? Appears identical.
We'll see.

Steve, specify a 3/4" shaft, they are available here in UK. Gemini have clone CVT they say are OK, personally, Comet, GTC or Max Torque.

Ok, I’ve matched buying an engine with a 3/4” shaft and a clone 3/4” torque converter .
Thanks for all your advice folks
