outer fork cap is 49mm, inner wrench is a 36mm octagon.
you have to do a search here for different weight fork oils, but I think 99% would recommend a 5wt fluid, at least in the inner chamber

A suspension guy could explain this much better than I but the twin chamber forks are not designed to have their action manipulated by different 'weights' of oil.
I whole-heartedly recommend using the Smart Performance 215.VM2.K5 'Taco Sauce' in your forks. Do a search in this forum for it or contact DaveJ.

I thought SPI's oil was different for different chambers??? They have SPI-3, SPI-4, and SPI-5, each for different areas and usage. Not sure if the numbers relate to oil weight or not.
BTW... i am loving my SPI oil and valving!!!

Kayaba uses 2.5 in the innerchamber. Showa is 5wt. I have been told that you run the lighter weight in the innerchamber so when the forks fade from heat you don't notice it as much (they are comparable to a shock).I have tried 2.5,3,5,and 10wt in the outter chamber and really couldn't notice a differance.

S1 is a 5wt.
sso1 comes in 5 and 2.5, but it is over priced. 39$ at local yamaha dealership.
