Maybe a bit early but I was looking for info on fuel stablisers and thought I'd compile the 'DSC Knowledge' while I was at it:
Fuel Opinion seems divided between draining the petrol system completely and using fuel stabiliser - (Motrex got a good mention and prevented tank corrosion) - stabliser seems to be the preferred route for bikes with injectors.
Battery Standary maintenance and using a battery optimiser of some sort came up often but only with the battery either indoors or in heated garage to prevent frost damage.
Oil If I understand right - it seems to be ok the leave fully synthetic oil in a bike over winter but for any other type an oil and filter change seems to be advised before storage.
Tyres F & R stands were mentioned a few times - but I also read about over inflating the tyres by 5-10 psi.
Sprays WD-40 got a few honrable mentions along with GT40 (Teflon added) and Worth products generally rated highly - (esp the dry chain lube).
There is also a product new to me that seems to be getting good reviews, maybe someone could comment: ACF-50
ACF50 Website link here I've used a Vacc-bag now for three years with good results:
