Hi Patrik, I bought an Aprilia air cooled 280 in a box. Had some bits done and started to put it back together. In the box with the Gearbox bits, ther is a tensioner of some sort which I can't place. Nothing the like on the SWM 125 and 280's I've rebuilt so far. any ideas ? I can send a pic but I wanted a first thought. Wierd, I usually fathom things out but this has got me boggeled.
Thanks,
Phil
