144 power valve dowel pin

I am installing a 144 kit. The new cylinder does not come with the dowel pin that holds the power valve shaft at one end. I am hoping to use the one from the 125 cylinder but cannot get it out. Does anyone have a trick for removing this dowel pin or am I stuck ordering a new one?

I remember a few posts about this a couple of years ago when the kits first came out . I think you may be able use a drill bit cut down to suit

Good idea. will see if I can match one up.

I was looking at the stock 125 cylinder that came on my CR and it does not have the dowel pin in it. Does it need this pin to run right? What exactly is its purpose?

The pin is there to keep the power valve shaft in place. Without it the shaft could move out of position. The bike should run fine without it, but if the shaft was to work its way out your power valve would get hung up.
