Basic work saw porting tips

[KenAustin-ix]

excellent Gordy ! I've been a motorcycle race engine builder for 50 years. I'm old. after building hotrod Harleys for a few years, I went on to tune race Kart engines, to me the ultimate in 2-stroke tuning. learned a lot. ported a lot. ruined some cylinders. your craft is making better use of tuning than my race motor work. way to go Brother.

Simple and to the point Gordy. Widening ports is generally safer than any vertical timing changes.
The only thing I would add to watch for folks, is the location of your piston ring ends (where they meet)
-typically they are located where there is full cylinder wall from top to bottom.
There is one locator pin for each ring.
Find them, scribe the location onto the wall, and don’t grind into their path.
Good luck folks, and happy grinding 👌

One of the best explanations I’ve seen on porting for beginners.

[WireWeHere]

Drawing a vertical center line on your piston to align with casting marks can be useful for holding your piston in line with where it'll run.

One thing for new guys is buy yourself a $30 dollar digital caliper for measuring the thousandths. Figure out how many thousandths = one degree and take off only about one to two degrees at a time. A little goes a LONG way. When I port most of my time is spent in the transfers making them more aerodynamic. Great stuff Gordy, thank you.

I have that same vice! Love it! It was given to me by an 80 year old neighbor of mine about 20 years ago now

Absolutely fantastic sage wisdom presented here! Pay attention here people! I’ve been in the performance automotive, motorcycle engine building arena for decades. He is giving you all of the secret information here for building performance from any engine. Thank you for sharing your knowledge here!

Just got myself a Holtzfforma 880 clone kit saw, this is exactly the info I'm looking for to clean up the ports prior to final assembly on it. Hopefully will make a good difference right away as the casting looks pretty average on first inspection. Thanks for sharing the knowledge Gordy

Great explanation. I love exchanging port timing numbers with my buddies and learning what works for some and doesn’t for others. Then you find the common denominator of the what and why’s. That’s really a good way to learn too if you’re starting out find guys on your level or close to and share your ideas.

Hey brother. Your spot on as far as my knowledge. I mean spot on. . Nice work bro. .. didnt know how digital even a gasket thickness makes on these little screamers . Not to often i run across a common sence mechanic and you have the goods . All and anyone who wants to learn something, needs to pay attention to you and your knowledge . Thanks man good to know there is others like myself that get after it and actually know what there talking about. Hey bro i eat sleep and thrive on these air pumps so i can pick up what your laying down . There very touchy and it has to be perfect or they wont run good or at all. 10 thumbs up to ya, pay attention people this man knows what hes sharing with you . 100 percent. . Thanks man appriciate you .

Really good explanation on atomization . I used to port and learned these concepts back in the late 70's early 80's . You sure can make a lot of difference from where you place rough and smooth surfaces in naturally aspirated engines . Not so much in force fed power though . Good video . :)

We have snow here, made my log job muddy so I finally can have a day in the shop. A little = alot in porting. Get comfortable and take your time. I recently replaced the intake and exhaust gasket in a Jeep 4.0 I built and ported 20 years ago. It was really nice to be able to see the fruits of my labor again after all these years and 438, 000 miles of reliability. The time spent on your builds will give you a higher level of confidence in yourself and your equipment. One will make mistakes but keep going, one day you will look back and be glad you did.

I don’t have a reason that I can put my finger on, but I’ve become addicted to your products and videos. You are quite a wonderful person and I thank you for sharing your business and knowledge with myself and surly others.

this made sense to me because I watched a guy do the same for air flow on a muscle car and hearing some old experts from the muscle car era talk about air flow. It's about keeping the motor cool. I think the best way to relate the heat in a motor is for anyone who has over heated their brakes in a big truck; you lose your brakes. The same goes with the power in a motor! when it gets too hot, it loses power! the cooler you can run a motor, the more efficient it will be for long days of cutting!
this was an excellent how to on increasing air flow without causing problems with the piston rings hanging on the edges. That part, I think was one of the top pointers on guidelines for shaping the ports for optimum air flow! Thanks, Gordy! Great video!

Great video! Honda discovered years ago that the intake charge mix and speed, over more volume made the most power. Polish exhaust, rough intake, and if possible increase intake charge speed by modification of venturi effect and distance to intake at the cylinder.

Gordy has some serious saws falling trees.. Great vlog Gordy. Thank you for the detailed information. He also has the coolest work shop too...

[ScrewdriverTUNING]

Beautiful explanation on basic porting. I will be a watching all your videos because of this explanation keep up the great work🔥❤️‍🔥🧬

[MichaelLeger-oh]

Awesome video! Probably the best explanation I've heard yet about the mechanics of porting. Thanks.

[bennyblanko]

Thanks! Appreciate all your experience, knowledge and sharing.

Look there Gordy the grandson of two stroke commending you you know you’ve arrived I live on the east coast t and you two are the 2 stroke gurus from sea to sea be safe great videos
