What "Cylinder Head" do the chinese 100cc-110cc Engines use?

[asjdsm]

that is exactly the same head as of chonda 70's,,can u tell us the valve size of this,,shhould be 23,, it is stamped on the other side of the head,, the side to the right ,,,above the spark plug hole,,if u have any difficulty infinding i will take snaps and upload them,,

This is all I can see::o

kindly let us know when u complete ur thesis on the correct cylinder ,bore and stroke size of 70 cc bikes so that all the chonda bike making companies should act upon ur golden points and manufacture their bikes on ur theory

Unique 78=e22.

after too much search i came to the conclusion that all chondas 70cc and 100cc and 110cc bikes have exactly samne head design ,,with regards to the valves sizes,,all have 23mm inlet valve size and 20mm exhaust size,,
cam shat may or may not be different,,it is not known as i couldnt come accross a single bike that has valve timing diagram with it,,

^ The cylinder stats of a CD70 and a CD100 are same so according to stats you should be able to mount a CD100 cylinder on a CD70.
Not sure though because never tried such mods.
BTW the cylinder of my CD70 is marked with E15.

no cd 100 cylinder has different combustion chamber a bit bigger squish region.. also different moutning holes.. so cant be mounted on chonda's or hondas.

however a 4 wheeler 110cc cylinder and head are mountable on chondas.. without any change ..

can i install 100cc head and cylinder on my my STAR 70cc ......

old one apni umr pori kr chuka hai ...

any one have an idea ...

center weight pr kitna assar pre ga ..

already 78cm and company installed head ...

[asjdsm]

WELL I was also interested to know it but still no answer..
stroke of 78cc/97cc/107cc/110cc/125cc are same 49.5mm

if a 107 cc cylinder can be mounted on 78cc then i think a 97cc can also be mounted.

for head i would recomend to use stock ..

as inlet/exhaust ports are same size for 78/100/110cc
