I have noticed at high RPM shifts between 1st and 2nd that there is alot of noise, a rattling of the shift lever if you will, but iF I wait for the RPMs to come down before I shift there is not problem, I have never had any other problems, my bike is a 2006 maroon and black, I currently have about 9000 miles on her. I thought it might have been a clutch problem but I dont have any opther problems in the higher gears, it only 1st to and if I am slowing down and try to shift into 1st. Has any one else seen this.
