Gilera 125 vx 04 modal cuts out when reved up

Sounds like you have a problem with the choke on the carburetor. I'm not familiar with this scooter. Does it have an automatic choke or manual? Is it possible for you to post a video of the problem? I will know better what the issue is after hearing it.

take side casing off on engine then take variator off then change it

yes this will require the 125 main jet pilot jet and needle vxr 180 only dna 180 i beleev is different

clean the carb out...make sure you clean the jets!!!

u are better off replacing the whole engine bec in my exsperince u will spend around £200 pound fixing that u could pick up a another gilera runner engine for £150-£200 from ebay etc

Yours is not a battery or oil problem. Rather, it is a fuel delivery problem, probably not enough. Possibly from a dirty carb OR, could it be cold and you need more choke until it heats up? You replaced your plug with the proper value plug, right???

First stop is: Is your fuel fresh? If not, burn up what you have. You could drain it but I don't recommend this procedure. What will you do with what you drain out? Do what ever you need to do to get it out of the tank. Do you ride daily or does this bike sit for periods? I suggest you use a fuel system cleaner - fuel injector cleaner is one option - use no more than the container tells you to use. Another thing, if you don't ride frequently, consider protecting your clean system with a fuel stabilizer, STA-BIL is one brand. Get it at the auto parts place or from your Gilera dealer. While there, ask them for any recommendations they may have. Questions there are free and always based on their best knowledge of their own euipment.

Sounds like a worn bearing or bushing...
Take to a good mecanic to dismantle to check everything out

you went through the electric. system, now check fuel supply filter, tank, valve carb bowl for dirt
