KX Fork Conversion Questions

[QUOTE="Woodsquest, post: 932164, member: 57669"] MOre cut-n-paste: Use what you can and ask questions. **Why, yes I can***** Hey. Thanks for the write up. So the shim part is JUST on the upper triple clamp, correct? I think I always cringed when I saw shim and stem, so I quit reading previously. I was thinking the shim was in the lower triple clamp, where the stem was pressed in. On my bike, the stem pressed tightly into the lower triple clamp. From year to year on the KX lower triple clamp this is off by just a bit. I had one that way and had the hole in the triple clamp knurled, like how the kick starter knuckle is splined but not quite as deep. It cost me $5 at a machine shop that specializes in building race motors. Knurling does not remove any material, it only reshapes it to a ridged opening instead of a smooth one. The high points of the knurl now will allow the stem to fit tight. I think that any triple clamp newer than a 1996 will be a press fit to an H model KDX and one 1996 and older will be a tight fit but would benefit from a knurling. The machine shop in my area does this for wrist pins and pistons so that they fit snug and the bearing at the top of the rod will work against a non moving wrist pin. This same tool is what he used on my first conversion, a 1996 KX triple clamp. I later changed my KX triple clamps to an after market brand; Applied Racing or BRP, I can't remember. That needed 20 tons of pressure to fit the stem to the triple clamp. If you do the mod, be sure you check the fork tube size will fit the triple clamp as well. Not that a little machine shop work wouldn't be able to get everything to work right for only a few dollars, but it does save time and gets you riding much quicker. You sound like a fair garage mechanic. This mod is easier than rebuilding a fork or shock. I would rather do a KX / KDX fork conversion than to rebuild my rear shock any day. Heck, a top end job is several times harder to do with the KIPS and all compared to what it took me to swap front ends. [/QUOTE]
