Well I've put some Silkolene sae 15 Intermediate oil in with the standard springs.

I'll report back how it feels.

I love tinkering with the Tenere it's such an easy bike to work on, actually the same can be said for all the Yamahas I've had.

The sae 15 is blue I wonder if silkolene colour code their susp fluids or all the grades are blue, anyone know?
