Post up your ported cylinder Artwork

[Savage Saws]

Everything has to work together for the engine to work at it peak. Intake tract tuning intrigues me for sure Al. I think your right about the spit back to.

This is why I love this site Jason. So many people willing to brain storm. As i said, i'm only a pup in this porting game and you better believe i'm planing on trying to get my uppers better (precise angle and symmetry.) Scott kunz has been doing this for over 20 years and say he doesn't use them either. I'm not a kunz groupie either, its just guys like you and him do things for a reason due to experience.

I feel like they work for me and my style of building but, i also feel like i'm completely in the dark too. Frustraighting and exhilerating all at once!

This saw didn't have much thought go into into, I just started grinding. I would probly never do one like it again but it does run pretty good.

From a gas flow dynamic standpoint.

A small port stream,regardless of pressure will helix around the larger port flow, (finger flow around transfer stream)

As long as the transfers are aimed correctly the fingers will help. Probably not as noticeable as an ok chain vs a good chain.

I am sure case compression has a lot of influence on how well fingers can work.

Hi Guys, New to this site. Thanks for all the great posts and the constructive conversation it has been a great help to me. For a couple of years I have been playing with my own saws using a Dremel and got some gains but this fascination with porting has become an obsession resulting in a shipment from CC Specialty. I take you guys understand where I'm at.
Anyhow before finding this site and blindly following the writings of Gordon Jennings book I have been grinding away on a Meteor 353 (45mm) and my numbers are seriously high compared to what you guys are doing and I fear I have either stuffed it or its going to turn out more than I bargained for. The kicker is my gains till now haven't been that great and its time to regain some respect from my mates. If I was to post here would you help me turn this jug around and get it to run like it should?

The puzzle keeps me intrigued.

Recently I had a 440 tune 300 rpm higher with adding an airfilter when there was none prior. Maybe it was the spitback protector on the 440.

I once mentioned how a filter getting clogged up with fines can actually lean the saw out and burn it up. A few people said that ain't how it works. This is a great example of how that works. It messes with the flow just enough to lose fuel but not air.

Welcome to OPE Darryll,
I'm Dan.
Post some pics for us here, but start a thread dedicated to fixing what you have so it doesn't clutter this one up. If it can be saved this is the group that will help you do it!

Did you get all of that aluminum swarf from my unicorn out of your vagina yet, or does it give some magical tingling?

Truly a work of art Jason. Hard to believe you could improve on what you already did so well, but you have.

Symmetry and angles/curves look factory.

i tidied up these ports on my CD2100 from this


to this, probably makes no difference at all but i sleep better at nite.

Looks much better, I would've had to do the same if I pulled a jug on one of my saws and seen that

Here are some pics of a stock factory cast step in the exhaust on the poulan pro 505/jonsered 2083.

Here is the result of some of the artwork the guys have posted. This is 395 I did quite a while ago; the owner said it may have 3 million ft. under its belt. Sounds like a lot of cutting to me!
