Post up your ported cylinder Artwork

Wow, really 108 on the exhaust? The 46mm is way higher except for aftermarket cylinders.

That cylinder was way different timing wise than the first one I ported. The first one I did was around 108-110 with no grinding. That one just I finished up was at 114* without grinding. I even triple and quadruple checked to make sure I was getting the same timing.

357 xpg im working on, putting a new meteor piston in it. Hoping for 180-190 psi.
Numbers are around 105, 125, 76

Looks good. Should be torquey

Hope so, I will try a 24" bar 3/8 on and see how it runs

Dagum dagum.. Nice work CFB

For the 371 I'm putting together.

Is that a turned down 268 piston?

It's a single ring Meteor 372 piston.

3120 cylinder that had hung a ring. Whoever was in the saw before had squared up and widened the exhaust port. The exhaust port roof was way to flat for how wide it was

Heres what the exhaust port looked like when I got it. It’s not the best picture but you guys should get the idea.

The intake looked like it hung a little too?

Shrapnel got jammed up between the piston skirt and the cylinder below the intake. Very small mark. It isn’t proud. I think the lighting and reflections makes it look way worse then it is.

1st jab at bridges. I might do these on a good cylinder cylinder and see how it runs (with it being ported as well) . Open to any advice.

Looks good. I like your last build, ran really nice.

Both my Ported MS460 (with a D cylinder) and my Asian 660 (Cross P+C - dynoed at 8.6 Hp) have bridge ports, and both run very strong so I'm a believer.

I hear if you do the transfers just right you don't need them, but I don't have right angle grinders and bridge ports just seem so much easier to do!

I also think they just have to direct more of the charge above the intake, which has to help expel the spent charge.

Nice, is that an 046-D cylinder?
