Re: Stability/wobble isues
I've checked everything I could think of after googling for issues like this. The tires are properly inflated and are in good shape as I've had them for a few thousand kilometers. The old tires were in pretty bad shape but I had no such problems (although the bike did behave like a sled but that's another issue). I've tried to play around with preload and damping settings on forks and shock and although they do make the bike behave differently they don't really change the situation. The wheel bearings have been changed recently too and the swingarm bearing seems to be ok. Either the steering bearings are badly installed or there's something about adjusting them that I don't get. But anyway, as far as I understand it, and unless you have set the preload on the steering really tight or really loose the bike shouldn't exhibit funny behavior during relaxed driving. I mean getting a tank-slapper at 180kmh or during heavy acceleration or breaking is one thing but getting sustained oscillations when coasting at 20 or 30 kmh shouldn't happen that easily. I may be completely mistaken but the truth is I don't know. My main problem is that this may be caused by a lot of different problems. The fact that it's relatively subtle, depending on the steering bearing setting means also that it may have been there in the past but I didn't give much attention to it until it became evident enough for me to decide to change the bearings. So I can't assume it's due to something I did since then. So the only approach I can see is starting to check/change anything I can think of including things such as fork oil, fork spriings/spacers, wheel bearings, swingarm bearings, shock bearings etc. etc. and this still gives me no guarantee that the problem will go away. So in the end I think that the lighter to the gas tank approach is both cheaper and less painful. I hope someone in here will have a better idea.
