You got an allen key? Yep that's the only tool mine had too but I also bought mine used. I would leave the airbox on (unless somebody already has pulled it off). You should be able to sort the cables without pulling it. When you pull one of the air runners you have access to the filter (it runs across the box between the runners). Unless you have proof the belts have been changed, change them they be real old. The Ducati ones are really pricey, so look for the Exact Fit brand which are way cheaper and identical. To get to the plugs, 2 screws are at the back edge of the seat. When you pull the seat off you'll see the one bolt that holds the tank. Take the air runners and seat trim off. Take the bolt out and raise the back of the tank (take the vent lines off) and under the back of the tank are two plastic disconnects. You squeeze the ring inwards and they'll release (they're dry breaks). They're old and brittle so go gently (I always have a spare pair on hand). BTW if the Desmo Times guy is still in business he'll have both the belts and disconnects. Now you're to the back plug and you can get the belt covers off if you need to. I think you can get to the front plug between the radiators but since I always change the plugs when doing a valve check I don't remember. 14 tooth front, try to not end up wearing it as a hat. Bad enough with the stock gearing
