Rear wheel wobbles from side to side and feels like its going to snap off its a 2004 gilera runner vx 125 coukd u plz as I dont feek safe on the bike thanks

Eww. Umm. Try to put it back together best you can and try to get another key made. Or you could just hotwire it every time.

Easy!
Just remove the exhaust muffler and remove the CENTER NUT of the rear wheel!

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

put a 172cc kit on it.....& try some new rollers if its slow to get to 40mph

can gilera vx runner 125 immobiliser be by passed 4 stroke

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

Not really. The rear-brake pads rotate inside the rear-wheel drum. Once you knock out the rear-axle bolt, you then bend-out the rear wheel. That way you could avoid having to take out the exhaust.
If you have to lay the bike down on its side to facilate the wheel removal, do so.

so is it ok and do u understand
