I did this on my 12 Thai built D22. What a PIA that was. .
Remove wheel and inner guard Take the whole thing out as it is easier to put back in.
Remove windscreen wiper 12mm and shroud ( careful the clips break easily).
Remove the 10mm bolt holding the antenna.
Remove the antenna lead...
just signed up. I have just bought a 2102 D22 ST-r CR 150k on the clock and it doesn't look to have done a lot of work. No doubt I will have questions. Going to check the timing chain today just to see how things look.
