the one in the link claims performance parts that I don't see (except the stupid spring tensioner that is crap) price seems high (esp when ebay whole kits are $99)
here at the shop, I sell the CDH A80 (once called PK80, now called superhawk) for $80 exchange or $90 outright
There are no 70 cc 2 stroke engines, they are called 66/80 cc,the 66cc is USA measurements and the 80 cc are Chinese measurements, so it's a 66 cc engine,the PK 80 and the Zeda 80's are 69.4 CC's, I prefer the Zeda 80's over the PK 80, I have both and the Zeda will go 45 mph with a 40 tooth rear sprocket and the PK 80 only about 35 mph, but the seeutec PK 80 top speed is 42 mph.
This one is only 68cc and it has a 48mm iron sleeved cylinder. I guess the reason the Chinese call it a 80cc or some other dumb numbers is they count the combustion chamber on the head. Now if it’s a 40mm stroke it is different than the 38mm which this one is but not by much. If the 3mm stroker
crank had worked with the pk80 I have it would be 74cc but this cylinder was meant for the 38mm stroke engine.
