Hi guys,


Rebuilding the front end on my 99 wr400. I've ordered seals etc but i need some fresh oil (i've no idea whats in the forks currently but it looks dirty).

Can anyone recommend some? and how much quantity i need? the PDF manual ive got doesnt have any fork information in sadly.

Any quality Fork Oil is good.  Use 5WT.  I use Maxima 85-150.  You can download the manual, but I believe 125cm from the top without the spring is a good start.
