Hi all first I'd like to say thanks for all the amazing information this site has to offer. I very recently purchased a 81 440 invader that is in amazing shape. It has never sat out a night in its life and only has 1009 miles on it. The bad thing is it has not run in 31 years. By reading posts on this site the first thing I'm going to do is pull the motor and do the crank seals,fuel lines,carbs and flush the fuel tank. What I'm wondering is can someone tell where I can find a kit for the fuel pump and what kit it takes also the needle and seat I need. Also where can I find a new spring for the primary clutch. Thank you.
