| Chi, you only needed the spacer because your bike was pre 2001 when all the bikes had shorter actuator rods. The aftermarket cylinders all need the longer rod of the post 2001 models, which of course an '04 998 is.
So FE, you already have the longer rod. Think about what a spacer will do...all that will happen if you put in a longer rod or spacer is that when you let the clutch lever out the clutch springs will push the actuator rod back towards the slave side of the bike as far as it needs for the clutch to engage. All you'll be doing in effect is to move the starting position of the piston further towards the end of the cylinder - I tried this with the STM and only succeeded in packing the slave out so far that the piston was pushed back further than the cylinder inlet and wouldn't move at all. You'll get more shove on the very first stroke of the lever but then the pressure will equalise, the starting position of the slave piston will just move back resulting in nothing more than a bit more fluid being pumped back into the reservoir.
You may think that you've bled it properly, but very often these things need to be vacuum or pressure bled. |
