Hi all, My VTR250 has a dodgy neutral switch (apparently is a common fault with these bikes). It works fine when cold but is hit and miss when hot. I checked the wiring and neutral lamp and it's fine. If I am to replace the switch (I found it on the right-side of the bike) do I need to drain the oil first? It looks like it lives in the gearbox sump. The workshop manual describes how to test the switch but not removal/replacement. Ta.
