same question for a 94 cr250. I used a quart already, and it's not to the proper level yet. Am I doing something wrong, adding too much, or is it normal to use a whole quart plus (on both forks, not apiece)

I have the actual 93 CR250R manual and will check tomorrow to confirm Matts figures. If all your doing is changing the oil, the amount of time you let the oil drain out of the forks is important for the amount needed to refill correctly. My advice is to let them drain for at least 3 hrs. After only 20 min. of drain time at 70 degrees, there will be about 12cc's of fluid left in the fork and after about 3 hrs approx. 8cc's will be left (this is out of my '02s manual)

I am actually changing the fork seals so they are gonna get completely disassembled and cleaned as I'm sure they've never been apart. I am assuming the figures above are the amount I need to add if the forks were dry?

Both bikes use the same forks. Showa 43mm inverted (USD). Use an oil level of about 100mm. That is measured from the top after you bleed the cartridge, springs out, forks collapsed.

Having a cheap fork oil level tool such as a Motion Pro unit will make it easy. Simply set the depth of the siphon tube and pull back on the plunger handle until it sucks air and your done. Basically it's just a big syringe with a long tube on it with a adjustable stop for setting the height.

Ok, here it is right out of the stock 93 CR250 manual (dry):

Standard (stock) spring (.38 kg/mm)(1coil at top of spring) - SS-7M or equivalent oil.
.... Standard oil level is 118mm (559cc)
....Maximum oil level 93mm (584cc)
....Minimum oil level 136mm (541cc)

Optional light spring (.36 kg/mm)(3coils at top of spring)
....Standard oil level is 116mm (561cc)
....Maximum oil level is 92mm (585cc)
....Minimum oil level is 134mm (543cc)

Optional Heavy spring (.40 kg/mm)(2 coils at top of spring)
....Standard oil level is 125mm (552cc)
....Maximum oil level is 101mm (576cc)
....Minimum oil level is 143mm (534cc)

Hope this helps even more, these figures are directly out of the original 93 CR250 manual (note the bike in my avatar! Its a pic of me on my '93 when it was brand new!) Good luck!! Man I love(d) that bike!!!

If you have any other questions about the '93 CR250 like torque specs or valve adjustment, whatever, feal free to ask away.
