<p>Hi Gary,</p>
<p></p>
<p>Thanks for getting back to me, it does not seem like there is a lot of people working on this for the newer fork.</p>
<p></p>
<p>I believe I am now on track with a viable solution, involving an upside down 1/4 steel key (looks like a key and acts like a key in a keyway) cut out of 3" flat bar, that fits into the 1" by 3/16" machined slot in the factory fork. By drilling an oversized hole in that plate at the new axle centre line, and then welding a piece of 3/16 plate…</p>

By drilling an oversized hole in that plate at the new axle centre line, and then welding a piece of 3/16 plate to the back of it to get back to the right width between the forks, and finally drilling a new hole for the axle bolt through the oversized hole and the 3/16 plate. It will be held to the fork by a bolt where the original axle hole was and 1 or 2 above it probably an AN4 midway and an AN3 at the top. Moving the axle down 1.5". I get over 10" plus of tip clearance, a bit better margin of safety than 7".</p>

<p>I spent a day trying to machine something similar to the above out of aluminum, but it became very complicated and hard to control the result.</p>
<p></p>
<p>Pictures coming.</p>
<p></p>
<p>Thanks again,</p>

<p>Have you checked the Viking website? I know they have a couple of nose fork spacers but I'm not sure if either fit the 701.</p>
<p></p>
<p>Another option would be to take the dimensions to a machine shop and have them fab one for you out of billet aluminum. </p>
