I'll make this as simple as I can. I bought heavier springs for my 600R. They're heavier than stock, but still undersprung for my weight. Long story short, couldn't pass up the deal, so I bought 'em. They are Race Tech .46 Kg springs, new and never used, still in the box. The springs are shorter than my stock springs, so I cut the PVC pipe to take up the difference plus I added 1.025" length since the Race Tech website states I should be running .57 Kg springs. I figured a little pre-load on the springs wouldn't hurt. I'm running Maxima 165/150 Fork oil at the recommended level. Compression adjusters on the bottom of the forks are set at 4 clicks out from seated. The Question With stock springs, there was no pre-load spacer needed. With these shorter Race Tech springs I need a 3.475" spacer plus I added an extra 1.025" to stiffen them up. Was this a bad idea? The Problem My bike doesn't like to turn anymore. Forks are too stiff and the bike doesn't want to "settle" into turns. Forks are too stiff and it feels like I'm riding on marbles under the front wheel and it just wants to wash out. Next Move I'm gonna set the compression adjuster to 8 clicks out from seated. (There are 16 clicks available). If the forks are still too stiff, I'm going to remove the extra 1.025" from the spacer tube in the forks. The fork oil I'm using is equivalent to 10wt oil. Maybe I should go down to 5 wt? Input needed and appreciated.
