That was the old stock piston box. Look at the size of the piston in the pic. That's a 350 piston. I was comparing the size difference of the two last night, just to get a physical idea of how big the big bore was. It may be hard to tell, but Neil's porting is as smooth as can be. It's almost a razor's edge on the bottom transfer ports. Not sure if he did it or it came from ESR that way, but the front exhaust port is almost smooth like glass.

You saying like the bottom edge of the sleeve is razor ?. Normally I'll use the a flapper wheel to smooth the bore side of the sleeve & kinda touch that edge with it while I'm doing that, just didnt hit that edge as much.
That casting was the ruffest casting inside I've ever got from ESR, like maybe the casting molds wasnt smoothed out as much. I had to carve out more than normal on the porting just to get the aluminum as smoothed & angled as it is.
The exhaust didnt turn out like normal either. I like them to be completely chrome, but it just wouldnt smooth out. Put like 7~8 hours just in the exhaust area, but hey, its cause I love a 2 stroke & want it to show.

Ok so maybe not a razor edge, but it is very pointed and distinguished. I am very happy with the port work. It looked very good to me.

I have a diamond stone I'll sometimes smooth that out with, same one I use for the port champhers. The idea for beveling the inner edge of the sleeve, is so you wont have any trouble with the rings when sliding the cylinder on. Some bore shops dont touch that area & you have to be careful to keep the rings from snagging. I dont leave it pointed to do anything, just how it turns out from beveling that inner sleeve wall. Now I do stagger that sleeve edge, to kinda make it easier for the flow to go into the main transfer more.

I was actually referring to the outer sleeve edge going into the main transfer. The bevel on the inner sleeve is normal to what I have always seen.

Update: 1/9/15
I ran into a factory design failure with my Hot Rods crank, so I have to tear the engine back down again to either put another crank in or notch the cases. So engine is on hold at the moment.

I got some new goodies in from ESR today! Got a stator cover, some gaskets and factory bolts, and a new ESR reed cage with carbon fiber reeds. Real excited to try out that reed cage!


Also had to do some work on my LSR axle. The aluminum sprocket hub spline were wore out and it had some play in it. So I had a new sprocket hub pressed on.
