Hey All Currently my bike has been odd and when I take off or at high speed it seems to slip or crunch...it is ok at medium speed..but not low or high. Is this a chain problem? It is my first bike and I will only be keeping it until the mid year so I don't really want to have any work done to it. Is there anyway I can fix this myself without special tools. I realise this may have been covered a million times so sorry for asking, but I am a total newby. I looked at this: https://netrider.net.au/articles/?page=chainadjustment But I am still not sure as I am not the mechanic type. Anyway thanks in advance.
