Please critique my grinding.

Just looking for some critism of these ports. I don't have a right angle head and my transfers aren't as smooth as I would like them to be. If you see any area to improve please tell me.

Bloody nice looking!

Looks good to me. Transfers are the toughest part. Good job, nice beveled edges.

 

[redfin]

Good deal thank you. Nothing stands out that needs improvement?

 

[JC360]

Looks like ya need a bit more practice.
Being the nice guy that I am , I guess I could let you practice some more on one of mine...

The timing numbers are more important than how smooth or good looking. My hands are bad shaky but my engines WORK!!!

The trick is to get the air to go where and when you want.

i have a 036 pro cylinder i can send you to practice on .....oh , hows youre finger ports coming along ....lol

Looks nice! Much smoother than I ever do.

I agree.

Sure, just don't be all meaners and stuff if its a big turd.

Even without adjusting the timing, it will flow alot better than stock. With a quality muffmod and tuned, it'll make noticeably more power.

Work looks good. Keep an eye on port shape as you can square up the general shape and gain more flow without approaching max width which is where many cyls get ruined by ports eating a ring. Read up on each models port style and shapes, lots of good pics and info on the forums. I would highly recommend getting a degree wheel and start checking timing numbers and you'll be surprised how quickly it'll start making sense when you see the action first hand. Tlandrum had a very simple description of how to rotate thru each port and get your #s. Really the timing on some saws can be twice the gain over porting and of coarse together make a real runner. Hope this info helps. Ken

Nice ports you can square the intake up more since it doesn't have rings riding over it. The bottom edge is where the flow happens first.

Mines real rough by comparison. I'm considering removing the dust before assembly in the future.

Nah, the rings will just push that aside.

Hey Mike, are you saying I should go deeper into the corners?

Square up the bottom part with just a small arc.

Great how you ground out a complete cylinder out of a block of aluminum!

I don't know how the cylinder lines up with the crankcase, but I had to cut out a LOT on the cylinder and crankcase sides to get a smooth transition on the transfer ports. I didn't muddle with the openings of the TP's, but did a lot of blending on the runners.
I really like how the saw runs now with the porting, as well as a bigger carb.
I found the saw likes about a 30:1 mix now though, while before it was 40:1.

Will do man. Thanks.

I honestly thought that was the "before" picture
