Hi folks My first post here so I hope I am putting this in the right place. I took my CBT in dec 2015 so haven't been riding too long. I have a Yamaha YBR 125 (2010 model, about 2,500 miles) which I have been commuting on and so far it has been fine. I recently left it parked up for a couple of weeks while I got the train to a new job but when I started it up and rode it around again, I started to hear a slight tapping sound. The bike seems structurally stable (I have looked it over, checked bolts, looked for cracks or anything amiss etc but all seems ok). The power seems fine too - it isn't struggling or lagging when I rev, although when I stop revving (but am still moving) I can hear the sound then - a sort of rough, tapping sound/sensation (Apologies if that seems a bit vague but hard to describe accurately when I am also concentrating on riding safely and have a crash helmet blocking my hearing I haven't had any spills or knocks on my bike and up and until now, had experienced no issues. But something does seem 'off'' and thought I would see if anyone else has had something similar or if there is a really obvious solution, before I take it to a garage to be checked. Cheers!
