A 5 year old could fit a PCV + AT as long as they read all the instructions then look at the bike visualise where everything goes check instructions again and fit putting my map in to the PCV takes about 5 seconds the bit where peeps (as you like to call em - cute) go wrong is not reading the instructions and connecting incorrectly or not tuning on the AT in the PCV
