I was thinking about the air filter set up on the Ten last night after adjusting the chain. The plastic side panel I can't see being hideously expensive, and the DNA stage 2 filters for the X and R's is basically a sidepanel with a filter in to allow more air in, so it wouldn't be too hard to make a sidepanel with some filter in to give more air surely?
Now the problem comes with setting the fuelling as I don't think the XT ECU's are reprogrammable like the SAGEM ones on my old Caponord, KTM's etc. This is where the PCIII comes in, as it sits between the ECU and the injectors and changes the signal to the injectors. Only changes the fuelling, not the ignition sadly.
Are there K&N or DNA filters available for the Tens?
