The previous owner of my NC23 said he used Unleaded petrol, I ran it like that had over fueling problems
My mechanic sync my carburetter and clean my fuel pump out, he said to run leaded petrol, the friend with her GSXR400 runs leaded and my cousin nc23 ran leaded. So ran leaded but bike became really sluggish getting (145km/h in 6th gear @ 10rpm not moving)... So going back to unleaded petrol/gas

Just wanted to get your input?

Unleaded dude...There is not one person on here (apart from the odd racer running avgas) that is running their 400 on leaded fuel.

Surprised you can even still get it on the forecourt, it's long-since banned in the UK.

Lol! That 4 you, South Africa dude! Governments waiting till 2012 to think GREEN

Japan has also been unleaded since the 80s so not quite sure why your mates are running leaded, the bikes are designed to run unleaded.
