Has anyone used them?... i'm sure i've seen a few fitted and wondered what the differences are between them and say the Piper vernier pulleys? They're quite a bit cheaper and must be for a reason, lol! Maybe the adjustment is more coarse and harder to make the very fine changes?

never used them but i like the idea of the locking pin, i'm sure you will still get fine adjustment

I have them, you still do get fine adjustment but is just not as simple to adjust the cam timing

How do they actually work then, I've only seen a set fitted and couldn't quite understand how they could be finely adjusted ?

2 degrees per peg hole on the cam which is 4 degrees of crank
they are steel and last unlike alloy ones which wear and eat through your belt
they have a far greater service life than alloy pulleys

Thanks Tony

have you had a look at the cat cams pulleys Paul ?

They also do these in alloy, unlike others you have to accept the timing ending as near as possible, rather than where you want it to within 0 degrees out, seems pointless when the idea is the total adjustability, these are limited by the holes in cam versus pulleys, and not infinite like others.

i have the quaffe pullys on my yb, took me and a mate a while to time them up though, the pins are all off set to each other, think they look nice compared to the normal design verniers

Paul ,

With locking pin pulleys you will still get the fine adjustment ..

Hi, Quaiffe pulleys are good, sure.
They are more accurate that you say : 3° on crank.

Best regards.

Thanks for the response guys! Mark's building the engine and like anything he'll have the last say (when I previously mentioned them to him he hadn't used them before afaik), but just wanted to get people's views on here too!

Yeah I had a chat with Matt @ QEP when I was in there a while back. Look very nice in the flesh but pretty expensive being a true-lock pulley.

This is what i'm trying to clarify, whether the loss of adjustment will actually be worth worrying about... down to the mapper I suppose.

Thanks for that Chris, but your pulley shown is a true locking pulley which has similar adjustments to a regular vernier doesn't it, and obviously more expensive than the Quaife?

As for serious power... depends what your definition of 'serious' is lol... 450ish

Great pic there Claude, makes more sense now!

I guess it's just a question of whether Mark's happy with that adjustment level or not?... we'll see!
