Thanks for the info Gina, I think I'll do it after the first service.
Where did you get the parts? Is it reversable? I ask that because if I did it and then had another non-related problem I suppose they could say I'd invalidated the warranty.
I am mechanically competent but I have always worked on older stuff so warranties were not an issue.
They also told me that if I had the off road pipes it wouldn't need any tuning. I'll have a look through this site to check that out.
My son has used a local guy for tuning his GSXR so I might get the TBA on it before doing anything to it, and then again after to see the difference.
