Yeah, there's a good idea.. Lie to the person about the problem..
How about you just take the clutch cover off, have a look, then you will know exactly what to tell the person you are trying to sell it to? Don't you think that would be the honest thing to do?
Remind me to never ever think about buying anything from you. Holy crap..
I promise you, you will never get anyone on this site to advise you to deceive someone when trying to sell them a bike. It's just not how we do things here.
If you want to do that, you probably won't find yourself welcome here long.
