well ever since i changed my clutch which is working perfectly now...
every so often it starts to get very very stiff or sticky... but i just spray some wd-40 on it... and it is loose and un-sticky... i have to do this every 2 months... ive had my new clutch for about 6 months... any suggestions?

Same thing here.....I'll pull the slave and fork, grease everything, but the stiffness returns in about a month....still working on a fix.

I would recommend using a proper grease after unsticking the parts with WD40. While WD40 is a wonderful thing that unstick a lot of mechanical stiffnesses, it can also be washed away quickly and therefore is not supposed to be a lubricant. Also, you don't want to accidentally get the volatile WD40 onto the friction surfaces of the clutch.

what do u recommend ?
i use wd40 cause the ease of use.. just spraying... as its not easy to get to it... i just spray into the hold which is plugged with a rubber fitting
whre u can see the release fork

Also, usually stiff and sticky clutch pedal is usually not from the clutch fork but most likely from lack of grease between the clutch release bearing and tranny input shaft sleeve. Sounds like you didn't get enough grease in there in your recent clutch job. I'm wondering if it's possible to wedge some grease between the bearing and the sleeve through the clutch fork hole?

what about some lube spray?

I don't think it's a good idea to spray WD40 in there. You need high-temp grease for clutch-release moving parts for the grease to stay there. Problem is the clutch release bearing has a "trough" on the inside where you can (and need to) store quite some grease in there and unfortunately you can only access that trough while the tranny is out.

For a quick fix, I'm thinking since the S2000 clutch release bearing is of "pull"-type, maybe it's possible to wedge in the high-temp grease between the bearing inner race and the input shaft sleeve while you have the slave cylinder and fork out of position. Use the tip of a long flat-blade screwdriver to do the job. Pressing the clutch afterwards will move the bearing towards the grease on the input shaft sleeve and hopefully it'll pull the grease in from there.

I have general-purpose grease spray but am not sure if they have high-temp ones. In any case, they should still be much better than WD40. The key is to get the grease between the bearing and the tranny input shaft sleeve but not onto the friction surfaces.

I have teh same problem... so it seems. is it more noticable at lower rpms and driving speeds for you guys aswell? When I open it up on the highway and shift at high or redline rpm into 5th or 6th, its not that noticable. trying to relate here

I was thinking there is a lack of grease on the input shaft aswell. that was my first intuition when i bought the car.....
