Heat marks on my crankshaft
 

Hi fellow XT owners,

From the first time i got my XT600E engine, which was used from the Official Yamaha Distributor here in Greece, for training purposes and rebuilted for me, i have spotted those heat marks on the crankshaft.
From Yamaha service, I've been told that this is normal and most XT cranks have them.

Could you comment on the pics and tell me what do you think?
Do i have a problem or not?

Every XT crank I've seen has them.

Nice to hear it...i was a bit afraid that my crank would.
