My kymco jr100 has a very unstable idle.
When i accelerate (a little boost) it stays at like 4-5k rpm for several seconds before going down and nearly shutting down.(mixture screw tightened to the max). I tighten the idle screw and the rpm stays very high.
I tightenned the mixture screw to de max and loossen it 1,5 turn. Now the idle stays at 4k rpm.
I loosen it more, even worse. The idle goes up and down on its own.
Here are all the specs of my scooter:
55mm cylinder (SEE)
Bigger head (idk but it has bigger intake valve) that says kymco LAB4
CVK 24 carburator
Direct cone intake
Whatever this exhaust is (picture)
Please help me, i had 0 experience jumping into that project. I am open to any advice about anything (pls don’t be harsh
)
