need help for a standard gilera runner?

i bought a 50cc gilera runner (liquid cooled)
1 when its cold and i start it i have to give it throttle until it is warm enough to idle its self (gurgle because of sport pipe) and if i give it no throttle it will cut out straight away i was thinking this is the choke..

2 there were stupid neon strips that didn’t even glow properly (they look very very stubasicallyi basicly took them out.. i found out as i took it off that propera propbasically, basicly it was powered to the ignition.. it had a blue pod thing where one wire goes through and you put the connecting wire through and you close it shut and it powers.. (i forgthey’ret theyre called.) but i snipped the neon wire closeish to the blue thing and taped it with electric tape.. would this be ok to leave it just taped? or will it still drain power from battery?

3 petrol gauge… when you fill the bike up it goes to empty.. when you drive a couple of miles it goes to full and is norman again..but ts just when its totally full how do i sort this?

if you an answer any i’d be very grateful, thanks

1 The sport pipe has probably messed up the carburation, making it run lean. That’s why it won’t idle when cold. It could also seize up if ridden hard due to the lean mixture.

2 Leave the wires taped, it’ll be fine.

3 Are you looking at the gauge when you’re filling up? Does it suddenly go to full when you turn the ignition on? Fuel gauges on bikes are notoriously inaccurate, don’t worry about it.
