I don't want to sound like a tit but what am I looking at? I don't see anything wrong?
No probs Triggergee, if you don't know you need a 32mm socket & torque nut to 70NM, I would advise the use of some blue threadlock (not red) as added safety.
There is something very wrong under there. Where is the oil - I can see dust.If its still on then all seems good and you have the correct thickness output shaft it seems, but put the 12mm nut on to be sure.
With regards to the spotless sprocket area, at work I basically have access to an unlimited supply of solvents (so long as I take it during a nightshift ). I scraped out all the gunk and then used what we call Exxsol in an old hand pump spray bottle, with a large piece of cardboard under the bike to catch all the run off. I did the whole chain with it then put some lube on to stop things going rusty while the bike is laid up for a few weeks.Any advice on my Cam chain question above?!?!?
