| Note: | ||||
| 1. As for the 80cc, in fact there is no such cc bicycle engine in china market, we called our 47*38(bore*stroke) engine F80 before ,but now we correct it, because its displacement is only 66cc(from EPA test report). | ||||
| 2. How to caculate the engine capacity. The fomula is listed below. | ||||
| The volume of a cylinder=(bore area)x stroke | ||||
| Bore area= Bore x Bore x pi / 4. (pi has a value of 3.14159) | ||||
| Take our ZM70-P for example, its bore is 4.7cm(47mm), its stroke 3.8cm(38mm) | ||||
| 4.7×4.7÷4×3.14×3.8=66cc | ||||
| 3. We have rear mounted hand start engine, but not showed here. | ||||
