Here is a link to Thumpers maintenance notes. Among other things, he references the fork oil level.http://members.verizon.net/allofusmorrows/RE_maintenance.htmThere is a lot of good information there.
This is all spelled out if you buy a manual.To quote the Snidal Manual:" The capacity for replacement oil is 200 ml.
I'm trying to figure out where MORE than 200ml came from for AVLs. I saw 200 in Snidal as well.
I still have 200ml of atf-f in them and they do dive quite a bit on braking and stay down there while stopped until I let off the handlebars. I have clubman bars on so the weight is right over the forks. I figured lighter fork oil might feel the same or even be worse so I was going to try a higher weight. I was also wonder if was because I was "under-filled" at 200ml.
After a complete flush of the forks, filled in 200ml of fork oil.Tire pressure at 26 and i got a real bumpy front.Isn't 250ml a lot of oil in the fork?
50 ml is 1.7 ounces. This would raise the level in the tube what? about an inch? (I'm not gonna do the math because I don't know the diameter of the tube). Would some guys who actually know the mechanics & hydraulics of front forks please tell me what effect this has on my bike out on the road? (200 vs 250). The only thing I know for sure is that I sure as hell don't know. What I "think" is that the "number" is to make sure there's "enough". Let's put this thing to rest.
After a complete flush of the forks, filled in 200ml of fork oil.Tire pressure at 26 and i got a real bumpy front.
After adding 190 ml fork oil in my OFF The Center Stand G5, the oil level was 14" below the filler hole.The tip of the rod travelled 21 inches below the filler hole, before it touched the top of stud on which the spring rests.The oil level was 7" above the base of spring. When the bike was put on center stand, the compression on the spring was released and the fork elongated, the oil level changed by 1".
So Paaji, is your fork action smooth?I could understand that 190ml occupies about 8" in the fork tube but then what is the right amount?
It's a UCE. I thought the correct amount for a UCE was MORE than 200 ml. No? Why are you telling us about an incorrect amount of fork oil for a UCE on an AVL forum? Who cares about all these measurements when you're using an incorrect amount of oil? Or is it me who's wrong? Again?
AVL and G5 are almost same frames for all practical purposes. Wrong or right or whether 200 ml is correct or absolutely incorrect is in your head since many factors affect ride quality - read my post before this. I am writing what I have tried, what works for me and has worked for many other riders on this Forum and outside this Forum.
I remember saying long ago in this thread that I thought the "number" was just to make sure there was "enough" oil in the forks. I think we're both saying more or less the same thing. Another question: If the forks are "more or less" the same, why the wide disparity in amount recommended by UCE vs AVL owner's manuals? (Not to say I put much faith in the owner's manuals. I bought one from CMW when I first got my AVL. Total waste of money).
.... but when the factory-installed forks were drained out, there was always less oil coming out of forks - way less, something like 160 to 180 ml or 200 ml. Moreover one fork had more oil and one fork less oil in many motorcycles. Some had reported leaks with large volumes.That is why you see volumes ranging from 200 to 265 ml.
