Not all CG200s have the same ratios. Some where I have ratios for the Lifan 163FML and a Zongshen 167FML.

I have a spare transmission and i counted the tooth on Input and Output shafts.
I. O. 1. 13:37 2. 17:32 3. 20:28 4. 23:26 5. 25:24 But, the transmission in my Keeway - Zongshen is different, I don't know all gears tooth count, I only know for second gear, and it is I15 O28. So, it has close similar ratio in 2nd, but less tooths, tooths are bigger. I need new gears for third speed, because they are damaged and worn. I wonder if to use this spare gearbox shafts and gears or I need to buy another transmission. So i need some confirmation about the gear ratios of other bikes. |

But, the third gear had severe damage, on both gears. The reason may be that the 3rd gears are thinner than the others. I will attach a pic of the gears later. I ended up putting first 4 gears from my spare gearbox, and kept the 5th gear from Zongshen original. The reason is I could not combine org and spare gears. I ended up with little faster 1st and 4th gear, littttle slower 2nd and 3rd, and the same 5th. Here are the ratios: 1st org> 32/11= 2.90 1st spare> 36/13= 2.77 * 2nd org> 28/15= 1.87 2nd spare> 32/17= 1.88 * 3rd org> 25/18= 1.39 3rd spare> 28/20= 1.4* 4th org> 23/20= 1.15 4th spare> 26/23= 1.13 * 5th org> 21/22= 0.954 * 5th spare> 24/25= 0.96 * denotes ratio currently in my bike. Great is I now have normal 3rd gear, with full power and no whining noise. And just to note, my primary reduction is 3.333 (70/21). |
