Fork oil
Hello everyone, i am going to maintain my forks, so i would like to ask you what kind of fork oil do you use for your F4i bikes, is it 5w or 10w. The next season i will use my Honda only for track days, so what kind of oil can you recommend?

Or just go with what Honda recommends and uses, SS-8. Its a 10w, but oil ratings are not consistant and cannot be compared between brands. A 10w showa can be more like a 7w motul etc.
I've used SS8, then i switched to SS47 which is the oem fluid for USD hondas like the RR. I'm now running Maxima blue label 7w as it works with my setup better [valved for 10w rebound, but the stock compression valving which is too much with 10w and heavier springs].
You don't change fork fluid for track. That's not how suspensions really work. It can band aid certain problems, but adjsuting the suspension is so much easier.

Thanks a lot for the advices and your experience. I am certainly not like Marc Marquez, I would like to be like VR46 but actually I am not, just ride for fun and to escape from the reality for a while. I don’t change the oil because I will ride at the track. The reason is that it is time to maintain my forks – the front is too soft and goes down too much. I saw that the in the manual it is recommended SS-8 and I was wondering whether it is 5 or 10w, so I thought of buying Castrol 10w or Motorex racing 10w again.

Thats right about 150lbs, which is about 50lbs too much for the oem fork springs. Weirdly enough [probably because of passenger possibility] its about perfect for the rear shock spring.
The springs aren't worn, they are just much too light. .68kg/mm stock, where for 150lbs you should be right around a .9kg/mm spring.
