Where is the best source of 96-99 XR400 .38kg springs to use in my 96 KDX?

Forums were always the best source. Thumpertalk is a good one to ask on.... or a OEM Honda site.

ADV rider is one of the best forums, great advise a mature. Here's a link for the section for thumpers, you'll have to look for the XR400 thread.

Here's a link for Sonic Springs, they are a little cheaper then some of the other manufacturers.

I am putting an order together from MotoSport, they have the OEM springs in stock for $30 per spring. I will do the 1' schedule 40 pvc spacer mod, 5mm preload and motion pro bleeder valves but have some conflicting thoughts on oil wt. and volume. Any advice on a starting point would be a big help.

Thank you in advance for your time.

Maybe this should be in the suspension thread, sorry.

Mix 5 and 10wt.... 7.5 seems to be just about right. You will need 2 qts anyway....

OK, that is what I needed to know, thank you. How about volume per leg?

530ml approx. but is measured at 87mm + or - 2mm from the top of the collapsed fork leg.

This is measured with the forks completely collapsed and the rod pumped several time until there is no air in the forks. You will feel the resistance....


I should just say... refer to your manual. :wink:

Absolutely, I have the manual, I see the price of it as a cost of owning the bike. I also have the CP online. My KDX is down to the frame and I could not have done the work without this site, the kindness of the members who post and BOTH manuals.

Is this correct, I thought it was more like 120mm

Usable range is 87 - 100mm

All straight from the manual.

150 is borderline for any stock KDX springs... depending on the terrain. More like 135lbs is perfect for stock springs.

XR springs should improve your suspension... I would first try a heavier fork oil.

Is that for conventional '92 forks?

I am about to order the XR 400 springs but want to make sure that they are .38 kg. The sales guy does not know and his OEM rep is out or something for a few days.

Are the stock OEM springs .38?
