Do you just have to cut it and that's it? Or do you have to change something's?

Cheers.

You will have to change out the drive boss and a bigger main jet.

Any scooter or decent bike shop should sell them,there are loads online or ask your localkymco dealer for the parts,most stock them. Dont cut the cdi without 1st doing the boss and jet.

engine is gonna be in high revs, top speed will probably remain the same, belt wear will increase and mixture could be lean but uphill will be better.
higher revs require more fuel, so, smooth drive boss, 82 jet and then cdi cut. Just my advice  :)
