The triples are relatively easy to install. Removing all the OEM air ducting is the most time consuming part. When you remove it you will be very happy when you realise that you will never have to put it back on. Attaching the filter to the crankcase breathing tube is probably the most fiddly part.

@HansO and I'm sure he will set you up well if you ask him nicely. One of the really nice things about the RIII is that you can set it up for good economy when cruising, and progressively more power as you twist your right hand. Therefore you can get the best economy and the best power from the same tune.
