My bike has had a weave on the high speed sweepers since it was new. I tightened the neck bearings, that helped some. I added a ride str8, that helped. Last week I was standing beside my bike when I started it and the engine seemed to jump quite a bit. I took it in and the front motor mount was broken. I had the new one put in and I can't believe how bad it shakes the bike at idle. I talked to a friend of mine who had the same problem on his ultra, and he noticed when his motor mount was replaced his bike shook a lot more at idle.
Now I'm wondering if that front motor mount has been weak since the bike was new and broken for who knows how long, (the bike has 21000 mi).
I know that the engine is held in alignment by the heim joints but I wonder if that weak/broken front mount contributed to my weave problems?
I know that the new mount is a new design, maybe it's a lot stiffer than the old design. [smiley=nixweiss.gif]
