36mm carb swap

If you want more low down hit at the cost of top end, fit the ec125 or Suzuki rm125 cdi, but be warned, it's fierce, in the wet slippery conditions today I could barely grip at all. Also, use high octane fuel to resist pre-ignition.

Also as far as I'm aware the AS1 and AS2 crossover, keoon doesn't state any differing dimensions

It's not necessarily to increase compression, it is the "squish" that is important. As I understand it, this is just the rim that sits within the cylinder walls and how close it is to the top of the piston - it essentially forces the air/fuel into the the domed combustion area. The dome shape within the head would have to be shaved to keep the compression ratio the same or at safe levels depending on how much material is taken off the head.

So, in theory, the bigger your squish measurement is, you're bound to have an incomplete burn meaning poor economy and lacking power. This mod increases bottom end!

The AS1 carb is 15mm(front to back) longer, at 91mm in length than the AS2 carb, which is 75mm in length.
