PVC pipe is commonly used as spacers in many fork set ups. In fact, my
2000 Quota came from the factory with preload spacer installed - made
from PVC. At 27,000 miles - when I installed a different set of springs
- they've held up very well. I don't think you'll have any trouble.

"PVC spacer" has anyone ever taken their forks off after having one in
there for a long time? Was it beat to &*^&* and back or did it hold up
okay? I live on a really bumpy rural road...should I use the spacers or
not?.....so many questions...Whay do you think, Loopers?

Kevin,

I had the same problem with the 71 Ambo I used to own. I had some PVC
spacers added to stiffen things up and ran 30W oil. Every time I hit a
bump, the tank would bang when the forks rebounded to their stops.
Going against what would theoretically make no sense, I drained the 30W
oil out and replaced it with 7W oil. Banging was gone! Can't explain
it as you would think lower weight oil would cause a harder rebound, but

it did the opposite. I guess it allowed for more initial dive whereas
the 30W oil resisted the initial dive and rebounded harder. It's worth
a try, drain out the 30W oil and add 6oz of 7W fork oil to each side and

see what happens.

Good Luck.

I have a slight problem with my forks on my V7. I have asked some people


about it and all I got were vague answers. The problem is as follows:

When I go over railroad tracks, hit a small pothole or something that
causes the forks to operate in a severe fashion, the forks compress as
they should, and then return to their extended position and hit their
stops very hard. It's as if they don't have any oil in them, but they
do. I've put ATF in, then 20W50, then 30W fork oil and lastly 60W racing


oil. Nothing. Still does it. What the heck is going on? The seals don't
seem to be leaking. The bike only has 20,000 miles on it. 3000 put on by


me in the past year.

If it is something simple I'd like to know. I don't feel like dropping a


wad of cash on something simple.

Sorry about spelling aluminum wrong. I flunked a lot of english and math


in school.
