Sprocket sizes

After further investigation into the bikes bad performance have now found that's it's running a sprocket set up of 16/38 as opposed the standard 14/41which will hinder the quite alot I have been told.

So. My question is, what front sprocket woukd you use to recreate the 14/41/,ie would 13/38 give the same gearing as standard if that makes sense, and do the cg125 use the same sprocket /chain as the c90.

It's basic Math.

41/14 = 2.93
38/16 = 2.38
38/13 = 2.92

You MIGHT have a trouble with clearance if you use a smaller sprockets.

There is probably a reason they came from factory with 14/41 not 13/38
