so, what cc is it ?

@exoticg9 im not sure but it might be 66cc

@frozenveinz1 no shit, you always have to measure the cc's of the combustion chamber when the piston is bdc thats how its always is even for car engines. Also the lower crank case is measured when the piston is at bdc so it counts total of 80cc. I already know this shit because I work on engines all day like industrial gas welders (opposed twin and v-twin) and 4 cyl diesel engines including my hobby.

@30GB No YOU do more research. These engine kits are made at 48cc and 66cc. They advertise the 66 as an 80, not because of the lower crankcase (however the hell that works, it would equal double the actual displacement if they did), but because they also count the combustion chamber volume.

@30GB What type of bike frame does this fit??

[mogyver69]

The 70/80cc is the 66.7cc engine. They do make a 49cc engine too.... The head is round on the 49cc and the 70/80cc is more square... Nice video!

@spazamatron934 wtf? They are only 66cc they never made 49cc, iv researched alot and chinese people count the lower crank case as the displacement making total of 80cc but really its only 66cc. The reason people say theres a 49cc is because the law only allows 50cc and under but in reality its 66cc. Do more research before you call someone a fuck wit

[spazamatron934]

@30GB you're a fuckwit, they're made in 49cc and 66cc you weird piece of condescending shit

@SPRUCEEY i DID build my own but traded it for a lawn tractor, this engine is still going after 1800km and i love it. seems chinese engines are pretty good, i even have 2 honda clones and they work well other than the exhaust breaking off. Search my videos for homemade gas bike.

[SPRUCEEY]

just a quick question...

why didnt u build ur own engine??

u seem to think the whole thing is shit
