Title: Different YZ Actuators??
Post by: Tahitian_Red on September 25, 2013, 01:09:54 pm

Any difference between these two actuators, besides one being dirtier than the other?

I think they're the same, the angle the bottom photo is taken from throws off the perspective and makes it look a different shape.

Firko,

The top one is from my RT2MX and I was told the bottom one is a magnesium actuator from the 1975 YZ250/360's.  I didn't think the YZ-B actuators were magnesium, just the clutch and ignition covers.

The 250/360B ones had the word "Magnesium" cast on the inside.....they weigh a lot less too.

The one thing they had in common was they didn't work

Your right there Mic.....heaviest clutch pull in the world.....the only time you use it is to take off.....absolutely useless to try and slip it if your in a higher gear and no feel to it at all.

Davey,

Where on the inside would "Magnesium" be printed?

Sorry Red, only just spotted this, I would have to look at one but it's on the flat part next to where the cable goes....that looks like a plain old ally one.
