I won't bore you with the tank/airbox lid removal. Heres the tops of the TBs.
Have your screw driver and long nose pliers close by.
Static, they sit slightly open.
Just use your finger and you can push them down to close position which is best when you're removing the screws.
Just use a good fitting philips screw driver and crack off both screws, while holding the valve closed, I ran out of hand as you can guess.
I then use some needle nose pliers to pick out the 2 screws, if you have the valves closed, the screws can't go anywhere, just have all your tools handy.
Next just rotate the valve and fish out with the pliers. Its not loose enough to slide down into the TB so don't worry.
Repeat for the other side and your done.
RESULTS: the bike feels a bit more responsive/pokey in 5th and 6th gear, but I don't ride like a tw*t so I havent hoofed it about when testing. It could take some time for the ECU to remap the fuel accordingly, I don't know, I'm guessing the bike runs on a closed loop system cos I spotted a lambda in the exhaust, so it could just take a bit of running in so to speak. Ultimately, its a free mod which doesn't do any harm at all and takes about 30 mins.
