Please help, I've had my lifan now for some time but it won't go over 80kph/50mph. Is there anyway of getting it to go faster ?

It's only done 1200 kms and has had new plug, lead and carb clean.

I have read that because it's Chinese it's factory set to 50mph due to Chinese law.

There must be a way to get it to keep up with other scooters ?

Thanks guys
