I have a 2008 yz450f with about 77 hours. I have an RTT stabilizer on the bike also. I didn't like the way my bike handled. It felt unstable, deflected, too soft, I had no confidence in the handling of the bike, and the bike seemed to wander all over the place. I was afraid to push through rough sections of off-road because I felt as if I were going to wreck constantly. And after riding my friends 2008 yz250 two-stroke( his suspension is set up through the same expert but actually valved a bit softer), which felt very solid and confidence inspiring( can go into more detail if necessary), I knew something was up. I figured this was a suspension issue so I had my suspension serviced and set up stiffer than stock through a suspension expert. I ended up having a broken free piston which severely lessened one of the forks ability to function and almost made it like I was riding on one fork.After riding my bike in the same conditions I used to suffer in, I still have that unstable, no confidence feel that I had before my suspension was serviced. I am beginning to think this may not be a suspension issue. Does anyone have any ideas?
