to scottoiler or not to scottoiler

[Oldie]

I had to leave my FJR at home for my last trip to Spain (V5 hadn't arrived) so decided to take the Versys for a bit of fun in the mountains. I don't think that I even looked at the chain until I got home as I treat the bike just like my other shafties. Upon returning, chain still looked like new and no adjustment necessary. I'm a big fan

Interesting review of oilers in Ride Magazine:

The Tutoro gets top marks for best value.

Just ordered a Tutoro Auto (special summer offer:  £39.99 on eBay) which works by "utilising the vertical inertia direction changes and extending the apogee dwell period of the primary valve" - apparently    

Sounds very scientific so it must be true!  I think it actually means that a metal weight on top of the oil release valve gets jiggled about as the bike goes over bumps and the valve is somehow held in the open position for an extended period - maybe?   On the other hand, it may run on Unicorn's tears.  

We'll see how it compares to my previous vacuum-operated Scottoiler.
