I know there are still people out there sitting on the fence, as I was, about whether to go ahead and remove their AI, O2 and snorkel etc. Just do it and get the TTP breathe cover and DNA filter and tune up your module. You WILL NOT be sorry. You will be singing praises to anyone who will listen. I did this a couple of years ago now to my 08 EFI and kept meaning to write about how good it was. Finally got round to it. Bike still performing flawlessly and well enough to turn it into a keeper. Only downside (which is not really a negative) is m.p.g. went from 55 to 50. Shows how lean the standard set up is, and no way am I complaining about extra fuel costs. Some things are just worth it!
