Anybody else noticed a vibration develop in 1st,2nd,and 3rd gear between 3k and 4k rpms? Mine developed it right around the 650 mile mark. It got better after changing the rear end oil and the engine oil to amsoil products, but its still there. Also has anyone had a problem with the starter sticking on. That only happened once at around the 200 mile mark. Had to disconnect the battery to get it to stop. I had the switch off and the key out and the starter was still turning over. I turned the bike on, rolled down the street towerds home (was at my friends house) about a block away the starter disengaged. Havent had a problem with that since, and im a month and 825 miles into ownership. Any help on either subject would be greatly appreciated.
