Question about 2003 Yamaha WR 450 F
Im looking at buying a 2005 450 and the motor sounds like it has a knock in it is it common as its only got 1300ks on it and the owner said it was the same with all as its notice able

Ive always though mine was a bit noisy at idle, from the day I picked it up new.
Keep changing the oil regularly, check the valve clearances, if its starting to get a few miles on it may require a cam chain.
If it doesnt get worse and the bike runs well, and the knock is not there at higher rpm, it might not be a problem.
It could be simple like the crank balancer which is not going to work properly until is has a few revs.
A little hard to diagnose without hearing it sorry
