Took my 06 450f to litz racing in Blounteville ,TN. to drop it off to have the suspension redone for my weight today,and he said just bring it on in and we'll get on it:thumbsup: ,He revalved it and put new fluid in and set the sag. Now I just have to wait till monday when Iam off to try it out:cry: at the track. When he had the front forks off I noticed he had a micrometer measureing what looked to be like washers and stacking them on top of one another on the fork,what was he doing:prof: ? I also noted he took some part of the fork to a grinder and ground some off of something. All in all it took him about an hour to redo the suspension and I was pleased with his price $323.00 plus tax for a total of $382.38, I did not need springs. BTW he is with Kawasaki 's supermotard team this year and he had four 450f KLF's to turn into super motard bikes. He has been in the custom suspension business for 27 years and I'am looking foward to trying my bike out.
