I've just cleaned the bike as much as I could before it got dark and it's cleaned up really well. I'd blathered it in ACF50 before leaving but looking at the state of it when I got home I doubted if it would have survived without some kind of damage but first impression is that it's fine. The same can be said for Scottoiler's low temperature chain lube. I've given the chain a wipe over with some paraffin on a rag and it looks like new again. Even though they'd said the oil was good to about -20c it had frozen in the bottle when I went to top the reservoir up at Grong on the way back so I wasn't sure if it would have made it to the chain but my fears were without foundation. Admittedly I had to turn the dial up to prime to keep things moving when it was really cold but that's only a minor detail so I'm well chuffed. We'll be filing our reports to Scottoiler in the next week or so and I'd expect them to be selling the new oil next winter so when you decide to go out in the cold and use the thinner oil you'll know who tested it for you. Now who can I blag things from next?
