DEcosse, thanks for the reply. Haha, yep I replaced the correct sensor. The day I get something like THAT wrong will be the day I just hand the bike over and start trusting the monkeys at my local shop again

Tuneboy's been acting a little strange - I tried to clear the fault code but for some reason it didn't work. And, the code ended up resetting after 3 heat cycles. So I'll see if I get it again but for now everything's kosher. Cheers!
