hello a few weeks ago i bought a 2007 yamaha r6. it was garage kept and seemed in perfect condition. on the ride home getting up in revs i noticed a weird resonating sound in the 4-8k rpm range.it kinda sounds like wawawawawa if u sound it out loud. the bike is stock except a yoshimura slip on...

After my accident my shifting has been getting worse and worse to the point where it got stuck in third gear. I’m almost certain it’s my shift forks and few local shops told me the same thing. Is there a way I can replace the shift forks on my own? Or does anyone know any shops in portland/...
