hi.. today was going to change air filter today,, lifted the top 1 inch to have a look at filter as bike has been stood for 8 years the filter was clean as a whistle and felt dry so i left it in .. should i have done this or should i have changed it...regards jim......

Well, if you feel comfortable with it it's OK.
I would personally replace it.
If the bike has not been used for 8 years, you should totally empty the gas tank and clean it. You may have condensation or the bottom of the tank may contain water.
After cleaning, replace the gas filter.

Could not more strongly agree with Bert. Clean out the tank, run a can of injector cleaner through a tank full of fuel in the fuel system. BMW car places sell a BMW approved version. Alternatively Redline do a fuel system cleaner S1. Alternatively Techron is a very well respected fuel injector cleaner. Next get in and change all fluids and filters and also clean every terminal on the bike and treat them with DeOxit especially the earth points under the fuel tank.

You should remove the gas cap and check the gasket (only 4 screws to remove).
You may not have to replace it.
