Front Fork Spacer Question

1013 Views 3 Replies 3 Participants Last post by  evhid1
Installing the Race Tech gold valve and emulator and using Progressive springs. According to the Race Tech instructions setting up the pre-load I will have to cut 1 inch off my left fork spacer and 1/8th inch off my right fork spacer. For those that installed the Race Tech gold valve and emulator, does this sound right to you? Thanks in advance for any help.

Because you are not using RaceTech springs, those instructions are out the door.

I went with Sonic 1.2 kg/mm springs and used the stock spacers, plus a pvc spacer the same size as the emulator in the right fork. That gave me about 1.25" of loaded sag.

Since you are using the progressive springs, you'll have a different setup. Basically, you are wanting to shoot for some loaded sag figure. I went with 1.25". I can tell you that 1.25" forced me to drop the forks 10mm because the low-speed handling got a bit wierd, where 1.75" was fine without dropping the forks.

because the emulator is in the left leg, you'll want the right leg spacer to be longer to equal the length of the left spacer and emulator combo.
Also, do you have the small emulator for the cartridge side installation of the RaceTech upgrade? I just received mine (it was a warranty upgrade). I'll be installing it in a few weeks.

My spacer in the right leg is 6" and the spacer in the left leg is 4 1/8". That puts them 1" longer then the " Set Length ", so if I understand you correctly I need to increase my spacer length by 3/4" so I have the 1.75". Since I have the Progressive springs and you used the Sonic's I will have to check the static sag to be sure. Not sure but I think static sag should be 1.5 inches.
