    Alright guys seem to be quite active on this since getting my speedfight 2.

    So iv worked out where the oil leak was coming from, after taking the CVT cover off it seems to be coming from the 'gear housing' the seals gone looks like its been replaced before with a liquid gasket seal and thats now worn away allowing oil to seep into the CVT housing and out of a small drainage plug on the underside of the caseing.

    This leads me on to my next question when im going down the road and go over 30mph i can hear like a 'MMMMmmmmmmmmm' sound that gets louder as i get faster until i cant even hear the Leo Vince exhaust tone lol.

    When i let go of the throttle the whine (Mmmmmmmm) stops and as soon as i give it throttle again the whine starts. it dont do it when its on the centre stand?

    Any ideas?
