Hi I’m new to karting ,
iv just bought a crg framed Rotax 125 pre evo.
I’m just doing all the standard things before I go out on it , changed gear oil , cleaned carb , repaired reeds , checked fuel pump, new fuel lines etc…
Now we have gone into lock down I might have a go at the piston and rings. (What’s the worst that can happen ) Iv got a Compression tester for the barrel , my pressure is 125psi
Iv been looking on the web and am I right in thinking that a really good barrel pressure is between 145 to 155 psi . If so what psi is considered bad ?
I’m not a black belt mechanic just know enough to get by so any help and input tips or tricks will be appreciated
