Of course now it's been done I'm convinced it's got a high frequency tingle through the bars and footrests that wasn't there before...![/QUOTE] Might be worth experimenting with more mass added to your bar ends to try to dampen the vibes down. Either heavier style bar ends or placing some lead in the handlebar tubes, I seem to recall a post on this subject previously.
Thanks - I'd played about with that in the past but it made very little difference. Also I have the DP brush guards that eliminate the bar ends.
I wish, this problem started since I've changed them! I think it's a bit better, or I've got used to it now!
