[QUOTE="crazybrit, post: 1079455, member: 67247"] I don't have a mm tape handy. The 21" is pretty exact (supposed XR). The 18.5 for the OEM was about, it's somewhere between 18 3/8 and 18 1/2. Yep I bought they from a guy on ThumperTalk. He seemed cool and all that. I asked several times. He said they were from a 98 XR400, he removed them to add aftermarket springs. I deduced from this that they were OEM. Depending on what feedback I get here, I can I guess go back and ask him. Well. It all depends on whether or not hanging the fork (uncompressed) in free air is a valid measurement technique. If so, I have about 1/2mm of gap. I was thinking of using 4mm of preload, so thats a 4.5mm spacer. If this isn't a valid way to measure the gap, I'm possibly already preloading the spring just to get the fork cap on (with the two spacer caps installed -- clearly they can be removed). More importantly I need to get out my dial gauge and measure the thickness of the two springs and the distance between coils as clearly, given the length mismatch, I need to confirm the spring really is a .38. No point even bothering if it isn't. The whole point of this exercise was to go from stock .35 to .38. Tony [/QUOTE]
