I would keep an ear on it. These are known to be noisy. If it gets worse, I'd def check your valves. But for example, with my build, if I didn't hear anything, I'd be introuble. But I have different rockers and everything. So I would say you'd be okay, just be sure it doesn't get worse.
Yes, as was mentioned, these engines are noisy. I was worried about that at the beginning then I noticed that when my helmet was on it was really quiet.:lol:
Get some more hours on it then when you get the first service it would be a good time to check the valves.
I just put synthetic oil in along with a K&N Filter.. From videos i have watched and others i have talked to, it must be the normal sound of the bike.. I'll stay on top of it and if it gets louder I'll have the valves checked.. Thanks for the help..
