I recently changed the fork oil in my 2009 Speed Triple. I removed the forks, took off the top nut and pumped them upside down until they appeared empty then refilled. Then now seam hard despite compressing so have I overfilled them as I only measured the oil in a jug or is there an internal issue with a dirty valve or something.
Oil viscosity ? The air gap only takes effect as you compress the air if hard or stiff at top of stroke oil may be more viscous. To sort you could try adjustment or swapping for thinner oil. Or.. maybe your old oil was past it and this is better ? See how it feels .
What grade of oil did you put back in? How much did you put in? There is a specific measurement that is usually taken from the top of the fork to where the oil is, sometimes it’s measured with the spring in and the fork stanchion extended, sometimes without the spring, you need to know which method it is for those forks. This is much more important than actual amounts of oil in each leg.
I ended up stripping the forks and giving them a really good clean. There was loads of sludg in the bottom which I presume was causing the problem. So a thorough clean and fresh oil and happy days.
Just seen this. I'll be changing the fork oil in my 2015 Striple non-R, what is the air gap you use? I assume measured with the springs removed and fork compressed?
Not sure what you mean by air gap. I have done the dump and run lately, just filled in what i poured out. And if you dismantle the whole thing, just follow the instructions and pour in the correct amount.
Changed oil on my 2016 S, the fork moves a lot more and is slightly better, but still miles of my 2013 Speed triple in comfort and quality. Not sure what the problem is to be honest, maybe the 2016 requires more tweaking that the old one.
Does anyone know if the internal dampers are identical or handed. On the parts diagram they have different numbers, just wondering if someone has fitted 2 the same to my bike
