As stated the bike is a 2011,first chain went at 50hrs,replaced with a genuine camchain,25 hours later that one was stretched and jumped teeth as well(he had to walk out of the bush an hour each way,get tools and take his bike apart to get it going,so not happy),so in goes a third one.....he rides pretty hard,does GNCC's put isn't a rev limiter type rider.Valve clearances are sweet,tensioner is all good....maintained to a high standard.
He did want me to ask if it is normal for the crankshaft to have end float,it is .29 mm at the moment.
For the record he is a mechanic and is pretty on to it but this has him baffled.
Any opinions much appreciated.....
