For the best part of a year now my bike has been vibrating a hell of a lot, jerking into first, and jerking when going down gears and just being extremely rough. It was extremely disappointing and for the life of me i could not fix the problem.
I changed the sprockets, chain, went over the bugger so many times and all it was was the bottom front engine mount bolt being loose. I am so happy but kind of amazed at how something so mundane could have such a massive impact. I know this is probably common sense to most of you but i'm not exactly bike savvy. Maybe another noob can find this post and it'll help :)
