Guys I've got a small problem I hoping you may be able to shed some light on. My son has a Pitpro XR125, Jailing engine I think, anyway since new the thing dies from idle if you screw the throttle wide open quickly, slow it down a bit and its ok. It has a china Mikuni on it but I have also tried a Molkt carby as well with exactly the same result. I also noticed if you hold it wide open it stutters a bit at full revs.
Runs sweet as midrange, will idle all day and as I said will rev fine from idle if your not to quick on the twist. I have tried leaning it up and also made it a bit richer to no avail, any advice would be appreciated.
