slice Posted April 9, 2013 Share Posted April 9, 2013 Some do some don't, might even be the type of oil your using or the temperature, mine spins slowly when it's cold but stops as the oil warms up, but if the revs are just below 1000 then it don't spin? 1 Link to comment Share on other sites More sharing options...
bippo Posted April 9, 2013 Share Posted April 9, 2013 Yeah it's normal. Mine does it too when up on the centre stand. I think it's something to do with the oil viscosity making things turn. I believe that as the engine warms and the oil gets thinner this happens less. Well that's my incredibly non-technical explanation! Sure someone else on here will correct me / explain better. Ha ha! 1 Link to comment Share on other sites More sharing options...

I believe that as the engine warms and the oil gets thinner this happens less. Well that's my incredibly non-technical explanation! Sure someone else on here will correct me / explain better. Ha ha! That pretty much covers it - there's enough drag from the oil in the clutch to pull the driven side round when it's cold. As the oil warms up and gets thinner this drag reduces and so the wheel stops turning. Richard Feynman time: take 2 discs of card on a couple of toothpicks and pop them into a bowl of treacle/golden syrup so they're facing each other but not touching. Turn one of the discs and the other should start moving as the syrup pulls on it. Now pop the syrup in the microwave until it's runny and do the same experiment - less or no turning. 1 Link to comment Share on other sites More sharing options...
