The most difficult part is removing the airbox, it can be very frustrating but with time and patience it can be done, I have done it a couple of times and it gets easier each time.
First remove the seat and fuel tank (have you removed the tank before?) then unbolt the oil cooler and pull it towards the front wheel no need to disconnect the pipes, remove the air filter and housing and plastics around the air intake, unbolt the bracket on the left-hand side of the bike holding the two coils just let this hang down out of the way, disconnect vacuum pipes etc. from the airbox.
May be a good time to take a break now 😉
Now comes the difficult part, loosen the two clamp’s holding the airbox to the top of the carb’s, there is also a screw on the right side holding the airbox to the frame, remove this, gently pull the airbox up off the carb’s sometimes the wiring loom running running along between the airbox and frame can restrict movement so just pull the loom to one side. When the rubber couplings are clear of the carb’s push the airbox forward towards the front wheel, it will only move a couple of centimetres, now push the airbox to the right side of the bike (I find it easier getting it out this side) it will take a lot of pushing and moving the airbox back and forward to get it out so just be careful not to put too much pressure on the carb’s themselves during this process as this is when the manifolds can be damaged, I found it useful to loosen the clamp’s on the bottom of the carb’s to the manifolds this can give you a little more movement and believe me you need all the space you can get with this job. Hopefully after some time (and probably some bad language 😄) you will have the airbox out.👍
Removing the carb’s themselves is now the easy part, disconnect the throttle cable, choke cable, fuel pipe and vacuum pipes, loosen off the manifold clamp’s fully and gently lift off the carb’s. If I have forgotten anything I apologize but I’m sure you will figure it out.
Good Luck.
p.s Going back on is just reversal of above but I’m afraid no easier 😔
