The CG 125 is just like an AK47, it was made to be cheap to make, cheap to maintain, reliable and just like the AK47 it was cloned to death...
But most of the design there is a limit of the thing they can do... You are not going to win a bench rest competiton with an Ak47, in the same way you are not going to outrun a real 250cc with a CG250. As it is, it's quite impresive that the CG 125 can be bored to 230cc and be reliable...
Like i said in other post, people used to sell 250cc for the OHV Cg 125.
Then the history would go like this:
-Kids dreams to beat his older brother that owns a CBX250
-Kids gets the CG 125 to 250
-Kids challenges his brother to race both bikes
-Kids ends up crying once his engine grenades out.
-Dad takes his Kid to the store who sold the kit and wants a WHOLE NEW ENGINE!!
-Dad leaves the store without any money, because it was stated that those kit have a low life before needing rebuid..
After a while, they get feed up and will only sell 230cc no more overboring to 250cc...
