I need some advice on the best way to refresh the forks on my NSR 250 sp. It has gone soft and I am sure it has never been refreshed. Here are the questions:

1. Buy all new seals and bits refresh the fork oil and reuse the stock spring


2. New seals, refresh oil and replace spring


3. Replace all internals with a cartridge style upgrade


4. Please suggest a fork oil weight as well thanks.



Money is a concern but if the cartridge designs are a vast improvement I may pop for it. The bike is not raced and just ridden on weekends. Any advice appreciated. Also, who is the best source to find the seals, springs etc.

Eddy i think you'll find sp forks are the cartridge type

Thanks Beaker.....I wouldn't have known. Any suggestions?

The springs are most likely OK, and fine for street riding, even for those of us who are a little on the portly side!

New oil and dust seals, and a change of fluid should see you OK. I tend to go for 12.5W personally (mix 10W and 15W 50:50), and add a little extra.

Thanks Andy. Can you recommend a source for the seals etc? The usual suspects? Are they a common crossover part number from Honda USA? I am a rookie so don't be afraid to walk me through it....I sourced the step by step off of the Dream Gate site and all of the quantities from this site. Thanks-

I picked up new seals for a MC16 from David Silvers spares in the uk. They also carry seals for all other NSR250 models. They spipped them to me in Oz in just under a week via post.

cheers,
