Or maybe the helmet. Every time I put on my rf-1000 for more than 20 minutes or so my left ear starts hurting. The helmet looks symmetrical inside and I'm pretty sure my ears are the same size....god damned twilight zone going on inside my helmet.
it could be you dont have the right shape head for that helmet not every helmet is good for everyone. all helmets fit different people in different ways. is this the frist helmet you bought or have you had other in the past because i know from experiance that i have had that agv helmets arent right for my head and i fit better into the shoei and the suomy helemts and HJC better than the others it all depends on your head
