Your friend may also want to make new preload spacers about 8 or 10mm longer (the grey PVC spacers above the spring) and use about 320cc's of Dexron ATF (about 7.5 weight) as fork oil. At 280 lbs, he should look into using heavier springs as you can only compensate so much for the added sprung weight. Jon Quote Link to comment Share on other sites More sharing options...
