PORTING CD-ROM

[BANSHEEFIEND]

I FOUND THIS CD ON EBAY AND FIGURED THAT I MIGHT AS WELL TRY IT FOR EIGHT BUCKS. ANYBODY HAVE ANY INFO ON IT?

Have not heard anything about it.

Let me know if you like it.

Says it includes a Yamaha service manual also.

It might be to good to be true.

But I'm a skeptic that way.

If I were you I'd pay an expert to port you bike for you. If you screw it up you'll be out a lot more than $8. Besides if it's such a good port job, why do they show pictures of the sides of some cylinders rather than showing the ports?

Porting a 2 stroke engine is alot more than what that $8.00 CD-ROM is going to tell you. It will not give you experience and know how.

 

It might tell you cut here, here, here and here. Anyone could tell you that. Making a port map isn't all that hard either as long as you have a degree wheel, a dial indicator and a few set up blocks.

 

But when it comes down to grinding away at your cylinders, none of that is going to matter. Experience using those tools will then matter. Knowing what you're seeing will matter.

 

If you happen to have a spare set of jugs laying around, who knows, maybe porting is something you'd be good at, but I wouldn't be willing to chop up a perfectly good set of cylinders just to see what happens my first time around if it meant I had to then go buy another perfectly good set of cylinders just so I could ride again/start all over.

On the opposite end of the argument...

 

IF you want to get into porting... And you want to expand your skill set... You have to start somewhere. Porting your first set of cylinders, and maybe ruining your first set of cylinders may be an acceptable risk.

 

I would read your CD, which hopefully has some useful information. Then I would spend a considerable amount of time and effort researching the methodology and theory of 2-stroke cylinder porting before you ever touch your barrels. Understand what your port modifications are accomplishing, and know why it works the way it does. Start at the basics and work your way to the advanced. When you've mastered all the basic concepts, start to hone in on the mathematics and engineering.

 

Get the right tools! Get a quality grinder with interchangable hand pieces. You'll want a right-angled hand piece. I recommend Foredom.

Get yourself some 2-stroke software. Start simple and work your way up. TSR is probably the best, but there are much cheaper alternatives to get you started. Do a Google Search on CARFOR software.

 

Good Luck,

i agree with ceg ,yo uneed to have the right tools$$$$ and the experiance in porting dozens of cylinders before yo u know what bits to use and how to accurately use them to hit your durations sizes and shapes . youll need special stuff like a thin high speed rotary grinder,a right angle pencil grinder to get into your transfers and various sets of carbide ,aluminm oxide,sicion carbide,diamond ,flapwheels ,buff wheels ,and the list goes on,thsoe cd's are a waste IMO and you wont extract near the power that the jugs are capable of .there is no cd that wil l teach yo u off your pc what is needed .by all means practice ,gotta lear n and start somewhere ,just take your time and dont make it an expensive mistake ,its alot easier to take steel off than it is to put it back on and one quick accidental slip up can ruin a good portjob

Hey, just got my cd and i am trying to get out of all caps, bad habit. But, i went through the cd tonight and it was extremely informative and precise. It doesn't tell how to do huge port alterations, but more of a fluff and buff, sleeve matching, small port work that will clean everything up a little and make more power. Kinda figured that was how it was going to be. On the other hand, i now have a 278 page cd-version of my old manual (it was falling apart). So, if you want a copy of the porting and/or manual, give me an email and i will try to send it to you. Both are in adobe and the manual is 18.8mb and the porting is 523kb.

[email protected] thanks i really need to see some stuff on the manuel.

If you are truely wanting to do your own porting, I have a set of race logic sport port templates w/instruction manual that I would sell you. I used them twice with great results.

There are gains in a simple clean up port , like removing flashing, smoothing and polishing exhaust ports, and matching the case to transfers.

Without modifing the acctual port size you can stay out of trouble.

I've ported hundreds of automotive heads, but I wouldn't dare alter the ports on the shee.....2 stroke waaaay diffarent.

All right, my attachment level for yahoo is 10 mb and the manual is 18.8mb. How can I get it to you guys who want it? I don't know computers that well.
