In August 2021, on my way to Jon Vicker’s annual BBQ at Millwood, my gearbox began playing up badly. I was finding it increasingly difficult to change down, especially from 6th to 5th and 5th to 4th. Clearly something needed to be done. Discussing the problem with Phil Stewart of Road and Race Transmissions (near Sevenoaks, Ken

This a DIY version of the Quaife Type 9 top cover that I first saw on Guy Lowe's gearbox. It makes it much easier to check and top up the gearbox oil level.

Having recently built a spare K-Series engine I had need to make an engine wiring loom from scratch. Working from the published Caterham K Series EU3 Wiring Diagram I found several problems:

It's not 800rpm, except perhaps for a millisecond or two. The rev counter only reads 800rpm because it only registers an average value.
Bushes are an interesting subject.
In the first place all bushes must introduce compliance into the suspension and this is likely to introduce certain non-linearities which could cause problems or could be used to remove design w
