I went for my first ride on the bike after building the new one and I ditched the lowering link this time. First ride without one.
AND holy hell doesn't that make a difference.
It shocked me (nice pun Leigh!!) how different it was. I've always ridden with a 2" lowering link and thought the bike handled ok. I guess it is what you get used too. Ditching it has transformed the bike, I can get away with a low seat now.
The balance of the bike and way it floats over bumps now (well....for a standard ttr suspension setup) is amazing. Turns in way better, way more stable, way more traction uphills, no more bottoming out on ruts etc. I've read lots that lowering links ruin most bikes handling, I also thought I'd read that the TTR and WRR benefited from a lowering link. Well now I've tried both, that sure isn't true in this case. So much better without.
I've just sent my spare suspension off to Teknik in NSW, I think I'm going to be in for a surprise. $1095 for full rebuilds, new valving front and rear, new springs front and rear and setup on the shock dyno. Feels like Christmas in July, I'm a bit excited.
Did you drop the front forks through the front yokes about 2 inches when you lowered the back that amount?
If you didn't that would have changed the steering head angle and account for the change in the bikes steering.
(I'm not sure if it is safe to drop the front that much though, would need to check that the front tyre couldn't hit the mudguard on full front suspension compression).
If you did, then what some people say about lowering links causing the rear shock to operate in the wrong part of its stroke must be the difference you are noticing
