So i've been having issues with my bike giving a bucking sensation while cruising around town. i've read where if you're in a higher gear at low RPM's it can cause it to bog down. this doesn't seem to be the case i still have the motion whether i'm at low or high RPM's. i thought that it subsided when i rode faster because i don't notice it, but i realized that the vibrations from the bike just overshadowed the bucking motion and that it is there if i focus hard enough on it. It's becoming an aggravation to ride because i feel like i'm riding on the back of a horse with it constantly bucking my arms. Any ideas or help would be greatly appreciated.
