Looking over the Valk Service manual I noticed that the left and right forks use different amounts of oil. (5.4 and 5.  I haven't messed with the forks on the Valk yet, but every other bike I've worked on I took great pains to fill the forks EXACTLY the same. Why are the left and right different? Have I been blowing it on my other bikes? |

I think the left has some sorta damper rod thing-a-majiggy. What ever its called the guts looks totally different then the right one.  |

Inside the right side is a shock. The inside volume is different left to right because of the differences. Most shops use the same standard for both sides as the EXACT measure is not that critical. I try to measure correctly just because that's the way I am. I've done 7 sets of forks on Valks and VTX's. They are nearly identical.

Not only are the volumes different for left vs. right, but IS vs. Std/Tourer is different too. I went to a scientific supply company and bought a 250mL graduated cyclinder to accomodate the manual's requirement for precise measurement, ±2.5mL. A cooking measuring cup just wasn't going to cut it!  |

The Only way that measuring the volume of oil...5.4 oz...will ever work, is if you completely disassemble the fork tubes and clean all the oil off of every part in there or you will have too much oil and it will ride pretty stiff.
Make a dipstick and check it using that method. That way you will be sure you have the right amount in there. I had my Honda shop put Progressive springs in 8 years ago and cussed them springs all this time until I had to change out oil seals. Obviously they had way too much oil in there because it rode really rough. I used the dipstick method and it rides like a dream now.

Steve, I have the same problem (I'll bet).
My supervalk came with the Progressive fork springs, and they ride perfectly. I had Progressive springs put in my other IS last year, and they are hard as heck and jolt me on even moderate bumps. I believe 10Wt fork oil is called for and is what was used, but I think they were overfilled a bit. Both '99 IS's have them, and the difference in the ride between them is significant. Frankly, I was considering putting the OE fork springs back in the bike that rides like a hardtail shock. I like a precice ride, but not that stiff.

Jess, have some oil removed. Some Valk owners have had a hard ride when installing Progressive springs discovered that removing 1-2oz. of fork oil softened the ride without sacrificing handling. When I had my forks rebuilt last year, the mechanic used Honda fork oil when he installed my Progressive springs. Mine rides beautifully.

This is interesting. I installed Progressive springs a couple of years ago and have never been happy w/ the ride. I recently replaced the right spring back to the stock spring w/ no results. Still too stiff. Does anyone know of a method for removing a couple of OZs of oil w/out removing the forks?

Get a large plastic syringe with tube on it. Take the tip cap off the fork, slip the tube down, and suck some out. Do the same amount on both sides.

I had the seals replaced with oem springs and it was really stiff and began to leak.I got new seals and bushings and added the Honda Fork Oil myself by fluid measurement as in book.My rides beautiful now without all the front brake dive and cornering "chatter".I think it is also important to get any air pockets out of the forks by exercising them before installing the top caps. |
