450 Clutch problem

[mike989]

Yes please, if you can find the part number that would be great.
I thought hydraulic fluid pushed and held the piston against the push rod. I guess I need to take mine apart to see what it looks like inside instead of guessing and talking about it.
Thanks.

Yes the clutch fluid pushes the piston agenst the push rod but when the piston has been pushed back it will have no pressure, just like when you push the pistons back when changing brake pads, but because of the week spring
it keeps pushing the piston back when you let go of the leaver. Brakes dont need a spring behind the piston because they do not have oil pressure trying to push the piston back in all the time.The spring is only to hold the piston agenst the push rod so the piston has not got 3 or 4mm of travel before it contacts the push rod.
If your dealer has not got the correct part go to a auto shop and see if they have one a bit stronger than the standared one.
I will find that part number ASAP 1st.

Sandman, Don't go to much out of your way, I have another bike to ride.

I'll be taking my unit apart tomorrow.

Got that part number for the spring.

Your Gas Gas dealer should be able to get it.

Thanks Sandman,
I'll have to order online, Las Vegas dosen't have dealership.

Sandman,
I've got a spring and a seperate rebuild kit on order.
In the mean time I took the slave unit off the 03 and put it on my 04 EC300, and the clutch works just fine. I took the 300 out for a couple hour ride today, and never missed a beat. The 03 acts the same way with the 04 slave unit on it.
I didn't pop the pistons out to compare springs.
I use Rotella 5-40 in all 3 GG bikes.

Mike,

Have you tried riding it?
I had some strange problems on a Honda road bike after changing fiber plates. The clutch would only just disengage and dragged a lot. After riding a little while and using the clutch it all settled down and went back to normal. I put it down to the fiber needing to wear a little and things to settle. Until it did the actuating rod had nothing to push against until the very last bit of lever travel. Only took about 10 miles and a few takeoffs to settle back into place.

[mike989]

Yes, I've ridden it around the neighborhood for 10-15 minutes. I will continue to do that hopefully things will go back to normal.
I soaked the plates in oil over night before I installed them.

Thanks.



I took it out today (1-12-08) with the clutch slave unit still acting up, during the ride the clutch starting working like normal. Don't know why, but it works.
I'll install the 1.5mm spring another day.
