Hi your airbox should be very soft and supple if its gone hard it will be very hard to fit and you will have a hard time making it seal well.one trick is to remove airbox and put in a plastic bag with some silicon spray for a few days .fit carbs first,removing starter cover gives a bit more clearanc...

Hi All,Took the Z1b out for first time today after winter fettling,i always thought the speedo seemed optimistic which was confirmed today when i went through a digital roadside MPH indicator at a registered 70 on my speedo it clocked 53,any ideas anyone if this can be corrected? Cheers Paul J.,

Just curious, now i have rebuilt top end before was running fine just smokey on start up...was getting 125 psi when warm on three pots slightly less on one.yet my a4 gives 150 psi on all four!!!.By the bye you dont have a decent colour coded circuit diagram for a z1b by any chance? or a description ...
