I lay my track bike up for winter, before I do I make sure its had a good wash / clean, and then thoroughly dried before coating with ACF50 & chain lubed, Fuel additive added and bike is run to get this through system, then tank is brimmed to top.
It is then placed on paddock stands with both tyres off floor, I don't like leaving it on an optimate for to long, so will alternate the optimate between this and the Enduro bike on a weekly basis.
Once spring arrives I start her up, run her for a few minutes and then change the oil for fresh.
I'm lucky in that my lock up is heated and never drops below freezing so the bikes remain dry whilst stored,
