Maybe this is normal or it's just me being paranoid all of a sudden, but I have noticed that the section where you pour in the oil is quite hot. It heats up quite dramatically after about 5 minutes. I can feel the heat when riding the bike. I recently changed the oil using MOTUL 5100 and the oil gauge indicates that the oil level is fine (as per ZX2R manual).
Is this normal? If not, what do you's think is the problem or what do I need to do?
Cheers
