power valve couplers
it's easy to see the difference in quality between the oem PV couplers and the waveeater couplers. but are the oem actually prone to failure like the PVs are?
i did a D plate and the PV stuff today. but after getting the stinger out yesterday and putting it back in today, by the time i got to the PV couplers i was exhausted. i gave up on em!! wow those things refuse to go where they're designed to go! i tried holding the spring and washer back while aligning the coupler and that didn't work. more than a few times the spring gave flight to the washer!
is there any trick to it? maybe i'll give them another shot when i'm not so greasy and grumpy.

Some jobs are just like that- go back to an impossible task after a coffee break, and it just falls together! I don't think the OEM couplers fail, they're just a god-awful fit! I didn't feel there was a trick to fitting them, but they are a bit tight. You'll get it, if you don't throw the f###ing things down the road first!!!

Stock couplers can flex, causing the timing of the powervalves to vary between cylinders.

I used a large screwdriver to persuade mine (gently) to fit. You want to just clear the opposite shaft, then center the coupler between the cylinders.

They just need to be aligned properly and then slid back over the longer shaft then back up on the short shaft make sure you seat them well on the short shaft. also if they are really hanging up check that there are no burrs on the shaft
