Petrol problems

i have a px 200 e with a 210 kit in it. the petrol light appears when deaccelating but theres fuel in the tank? also the scoot seems to splutter at around 45mph? can anyone help

new tank of petrol problem sorted.

With regards to the petrol light, check the fuel tank sender with a voltage meter, if it is faulty replace it.

thanks very much.

Thanks for the reply. It has a Malossi 210 kit in it and I think the standard carb. It’s a 1993 px without electric start. The problem could be that it has only done about 70 miles in over a year. Any help is appriciated.
