How much vibration are you actually experiencing? Have you ridden another motorcycle at that speed w/less vibration?
What gear are you in when you experience this?
And no....adding another steering damper is not recommended. Some heavier weighted bar ends may or may not help.
Seriously though....any motorcycle is going to have some degree of vibration at that speed.
Wait to you push past the 150mph mark
thanks. i just had a new tire, zzz 530 chain and a new front end put on 3 days ago. (forks, upper and lower tripple) the guy i bought it from did some damage. i figure it might be the rim..but when they installed the tire they didnt say anything about damage to the wheel. they are a very reputable shop (id rather not mention the name).
