Default Front end mod only

I'm going to have to have the fork seals replaced soon. I don't have much extra money to spend but thought that since I had the front suspension off that I'd consider replacing the fork springs at that time also. Is there a paticular brand of fork spring suggested for just upgrading the front. With the stock rear shock still in service does anyone think the ride will have a negative effect. Or should I just keep the stock fork springs for now. The bike has 28K on it. I ride by myself. Your thoughts group. Thanks ahead of time.

While riding did you ever think "These forks really sucK!"

yes = do a replacement

no = replacement not necessary

I went with RaceTech springs and their Gold-Valve system. But, I also did the rear shock too.

If you front forks are bad and need replacement, it is a good bet that your rear does too.

Only if the fork oil was somehow diluted to begin with; otherwise, heavier fork oil generally just makes everything worse. A better plan is to upgrade the fork springs to those most suitable for your weight, and replace the old fork oil with new fork oil in the OEM weight. If that doesn't help, then the next step is to re-valve the forks (using a Gold Valve kit, for example) and use the fork oil weight specified by the aftermarket valve manufacturer.

You cannot solve a spring problem by changing fork oil.

I have an extra set of hardly-used springs from Race Tech for a 165# solo rider. You can have them for the price of shipping, if you like. e-mail me at

+1 Heavier fork oil than OEM is not an improvement and makes the front end even more uncomfortably harsh than it already is. Been there tried that! After installing gold valves, Race Tech recommends only a 5wt oil. I've oft wondered how well a 5wt fluid might work with the OEM valving.

I like a blend of Honda oil at 6.7 wt with the stock valving.

It is important to mention that fork oils do not work like motor oils when comparing "weight". For example one can count on different brand motor oils having similar pour and flow qualities across a range of temperature if the weight of the oils is the same. Not so with fork fluids. One brand of fork oil at 10 wt can actually act "thinner" than another brand's 5 wt oil. Weight between different brands is not comparable and different brand 10 weight oils may have very different qualities.
