Could make your fork seals disappear too. Much safer to replace the stock spacers with ones that are slightly longer. I did that -- replaced my stock spacers with ones that were about 3/4" longer -- plus put a slightly heavier fork oil in (15w) -- and it firmed the fork up enough so that my front end no longer feels like mush in the twisties and no longer dives for the basement when I brake, yet still is supple enough that I can thump over the expansion joints on the 101 freeway without feeling like I'm riding a bucking bronco (rides better than my S-10 pickup truck with its stock suspension on that same stretch of pavement, that's for sure!). Or you could get the Progressive springs, they're a bit longer so do not require so much spacer to get a nicely controlled-but-still-supple front end. Of course, I'm up to around 200 pounds fully geared up nowdays, and often am hauling around 100 pounds of luggage and gear, so my mule needs all the springing she can get... springs designed for a scrawny 125 pound Japanese lad just doesn't work with all this blubber and gear aboard! -E> sure made the brake dive disappear

Those valves aren't meant to add pressure, they are there to equalize the pressure. What you are supposed to do is sit on the bike and press in the valve to let the pressure equalize with your weight in the saddle. As the man said, you will likely blow your seals by adding pressure. Pre-load via longer spacers, Progressive LR springs and tinkering with heavier wt fork oil and levels are a better bet.> On Mon, 2 May 2005, Adult Entertainer wrote: > > sure made the brake dive disappear > > Could make your fork seals disappear too. >

5 psi is nothing, dealers mech added 10 psi to each on my bike and told me about it, said it would ride better.

yep...makes sense that 5lbs of air pressure wouldn't blow the
seals...I figured the seals couldn't be that wimpy esp. on newer bikes
with fresher fork seals...on older bikes designed for no extra air
pressure, air fork caps/shrader valves were commonly added and some
air was put in to help older style forks.

Those valves make it great for getting the old seals out just add
pressure and stand to the side.

The backside of my fork says nothing about PSI. My owner's manual says
don't put air in the forks. For normal street use 5PSI probably isn't
going to cause fork seal failure, but bottoming out the front suspension
offroad may send the fork seals to that great fork-seal heaven in the sky.
KLR fork seals are not exactly the most robust things in this world,
though if not stressed they're good enough (sorta like much of the rest of
the bike, sigh).

What diameter PVC did you use, and what length?
I weigh 240 lbs and would like to add spacers to my forks.
Thanks,
Rob

FYI. I sent Fred an e-mail with the idea of putting spacers in the forks. He advised against it. He was sure the stock springs aren't progressive, and causing them to bottom with a longer spacer could damage the springs / forks. Thought you should know
