I need to change my fork seals on my WR426 and have a quick question. After you remove the fork cap, you have to press down the spring and insert a spanner wrench to be able to remove the cap from the the rest of the assembly. I don't have a spanner wrench and my box wrenches are too fat to fit between the spacer and the spring guide. What size wrench is required to be able to completely remove the fork cap? I need to buy a wrench of the appropriate size. If I can't get a narrow wrench, I'll buy a box wrench and just grind it down so that it is thin enough. Thanks.
