Yes one up three down and up to change down , down to change up.
So from neutral up to first, gently down to find neutral, down for second, down again for third, down for fourth (top)
Until you get used to riding again you sometimes might find a false neutral between other gears than first and second.
Also you will find many post on the forum regarding difficulty finding neutral, one tip is to select it while on the move other things to consider are clutch adjustment, proper lever.
Don't let all this put you off though, you have a great bike that will give you endless pleasure - get those pegs on and get it out for a spin
All the best - Bill
