Re: [ST] Front fork bottoming with RT Valves.

[Dan Wallander <newsgroup@xxxxxxxxxxxx>]

There is a small spring under the damper rod to cushion topping the 
fork, there is nothing to cushion bottoming the fork.  I'm thinking your 
forks are not set up properly if you are bottoming them on a speed bump, 
or you are hitting the bump way too fast and hard.

If you have 20,000 miles more or less on stock forks, your springs are 
sacked out and it's time to put race tech in there anyway (up through 04 
years).  Check your steering head bearings for play and service them if 
you haven't done so yet.  Rebuild your forks, new springs and Race Tech 
if you have the dough.

I weigh over 220 pounds and have never bottomed the fork.  Current setup 
is two turns on the RT emulators, 3mm on the tubes over the upper triple 
clamp, 10wt fork oil at 150mm from top (forks on bike on center stand), 
two turns on preload from full out, using 1kg race tech springs. 

Every time I take the forks apart, clean and reassemble (every 
year/about 12,000 miles), the bike feels like new again.  It's an 
amazing difference.  I'm still not completely satisfied with the front 
end setup, but I get it closer each year.  Maybe by the time I hit 
100,000 miles I'll finally have it right!
