Suspension

[frostman]

As i have already said i am new to bikes, i sometimes feel the back or front tyre twitch but this could be in my mind. I have checked the tyre pressures and their ok. The twitch could be in my mind and nerves but as the bike is a second hand Fazer 1000 Gen 1 i have been thinking the previous owner may have been adjusting it to suit him/herself and it may not be right for me. I weigh 19stone can anyone advise me on what settings the front and rear suspension should be on.

Thanks
