[QUOTE="PT564, post: 125367, member: 18177"] [b]XR 400[/b] First off -- gold valves will help a bit but you can just modify the stock valveing and it actually works pretty good... My suggestion is go with 43 Kg springs w/ 6mm of preload. Washers: Leave 6 of the 4 thousands thick washers in stack.... Thus, you'll remove quote a few. Set the oil ht at 4.5 in from the top with 7.5 wt oil (or mobil 1 ATF).. That should take care of the front... The rear is a different story though... PT [/QUOTE]
