So what happened, you installed a new clutch master and slave and you can't bleed it out? Is it a problem with the bleeder valve? Need more specific information if you can provide it.

well i did end up bleeding it but it still wont go in gear when its running. i have measured the movement of the slave cylinder and its 1.5cm. could my clutch have shat itself. its only 6-8 months old and i havnt thrashed it. also when the clutch goes in it doesnt feel as hard

What was the original reason for installing the kits?

i was driving home and when i put my foot on the clutch and changed gear it seemed that i hadnt put my clutch in the whole way but i had so i presumed the clutch master or slave was starting to die. u know how sometimes hydraulics gives u a little notice b4 it dies. well ive rebuilt them and i can see the slave pushing the fork when i put my foot on the clutch but the clutch doesnt seem as heavy to press as it used to be and it wont go into gear when the motor is running. ive measured the distance between the slave and the fork and when the clutch pedal is fully pressed the fork moves by 1.5cm. is that enough? im preety sure ive bled all the air out

Are you sure you've bleed it completely?

I've had this problem but only when there was abit of air still in the hydro line to the slave.

The best way IMHO to bleed the clutch cylinder is to loosen up the bleeder valve and put a hose on that which fits throughly, put that hose into the brake fluid box and depress the clutch pedal few times, addin' more fluid on the fly to ensure no air gets in.

This way I've usually managed to get it air free. It should travel more than 15mm I think 30-40mm is more like it. But I don't really measure this every month so I might be mistaken.

I'd try that before tearing the gearbox down to check out the clutch itself.

Do you have any "free play" in the pedal? there should be some before you really are pushing the master piston.
