(hypothetically) store a bike for 20-30 odd years..?? no chook pens please..
cheers
I dont think it can be done completely successfully without age damage, engine i would fill crankcase and cylinder/s COMPLETELY with oil, buy a comlete set of engine seals for fitting later,clean and grease EVERYTHING easily accessable,coat fork legs with crease, rims and spokes coat with grease OR spray with anti-water fluid (wd40 etc) every month or so (i would remove tyres so rim inners can be treated as well).I would also buy another seat foam and cover.... 30 years later just rewire your electrics,fit new tyres and tubes, service shocks and forks, drain refill engine and carb, GOOD TO GO! I would probable also store it in my house itself as its always drier in the house, sheds get moist with temp changes due poor ventilation,no insulation in walls/floors/roof cavity etc.
Phew, hope that helps!
