That sounds like 1.5 hp specs, pipe and other restrictions, you have work to do.

The Intake hole on hi torque cylinders looks 12mm but it not, measure it you will find they are 14mm+ but you can open it up more easIly

When you remove the cylinder to decarbonize You’ll want to remove the thick 1.5hp head gasket if it has one and put the .2 mm thin one treats sells, then inspect everything like rings, ring gap, cylinder bore etc. then you can dremel intake hole on the outside to at least 15 mm,

The stock tall 14 mm bing Za50 intakes are over 14mm already but you can dremel/bore them to 15 mm and use the 14-15mm carb but you can’t use the stock exhaust pipe or air box because of the restrictions so get a circuit type lowend type pipe and metal mesh filter.

You could follow these directions to get to 2hp if it works/not worth the work as far as I’m concerned, a aftermarket pipe and filter is way more power for less work.

If the cylinder and piston are in spec I would run a circuit pipe, metal mesh filter, 14mm bing and intake around 72 jet with 222 atomizer, less jet with 212a atomizer if it works good, possible single embossed ring leaner needle.

If You use 15mm bing then open up intake pipe to 15mm try 78 jet 217 atomizer, I would sand the head flat (it’s like 1.7-2mm) removing compression rings for a bit more power.

If cylinder is out of spec I’d go with the TCCD 50 cc kit and 15 mm bing, 14° timing and 35 tooth rear sprocket
