Hi guys
I have already searched on the forum regarding this topic, but I have to ask anyway. I find the general consensus that stock fork oil viscosity is 5W, the Yamaha Fork oil 01 equivalent.
Well, my suspension is stiff as hell on that oil. Very, very stiff. When I got the bike, suspension was incredibly soft -- too soft. Comfortable, but not very off-road capable. I upper it to 15W, which was way too much and it hydrolocked. Took it down to 10W, still too much. Took it down to 5W -- expecting success, but compression is still very hard even at ZERO clicks (ie. max clicks out). Rebound is also a tad slow despite 0 clicks (again, max (10?) clicks out).
This has made me wonder if 0W or 2,5W is the true equivalent to Yamaha's 01 fork oil. The oil changes were done at yamaha and my fork is in mint condition. Unfortunately they don't have the stock oil available, and also (I live in Colombia) don't have a lot of experience with this specific bike.
Have anyone experienced what I am experiencing?
I am planning to bring it down to 2,5W and, worst case scenario, 0W. Already spent 300 bucks on erroneous trials.
