allstarbanshee Posted June 30, 2007 Report Share Posted June 30, 2007 Hey guys got a quick question, im in the middle of porting a set of stock cyclinders, What are the 2 ports on the SIDES inside the actual cyclinder and what do they do? also is there anythign I can do to them to help out performance or leave them alone? Thanks A lot Justin Quote Link to comment Share on other sites More sharing options...
bansheefreak Posted June 30, 2007 Report Share Posted June 30, 2007 i would suggest if you dont know what they do you not touch anything... porting should be left to the pros.. but its your cyls so do what you want.. Quote Link to comment Share on other sites More sharing options...
Wallrat Posted June 30, 2007 Report Share Posted June 30, 2007 Those are the "I just bought a new set of cylinders" ports. Congrats on finding them, most people search long and hard before they decide on somebody to port their engine. Quote Link to comment Share on other sites More sharing options...
allstarbanshee Posted June 30, 2007 Author Report Share Posted June 30, 2007 I know what im doing, I was just wondering what those ports are for and how they work exactly Quote Link to comment Share on other sites More sharing options...

locogato11283 Posted July 1, 2007 Report Share Posted July 1, 2007 umm, i dont think you should be porting anything if you have to ask what the ports are and wat they do.. Quote Link to comment Share on other sites More sharing options...
Snopczynski Posted July 1, 2007 Report Share Posted July 1, 2007 (edited) Quit being pricks you guys, if you know then tell him. If you dont, then dont say anything. How is anybody supposed to learn how to do port work if they dont get practice doing it. I am gonna do some porting soon, I dont know what those ports are, I do know they are hooked to the transfers, but not sure if your supposed to do anything to the ports. If anyone tells me I shouldn't be doing it, then I will give you a giant middle finger and tell you to go get bent.

I have ported my own cylinders and the outcome was pretty good. Before you go porting your own cylinders you need to find out what to port, how big to make them, and all the angles to make the ports are very important. Best way to learn is to do it yourself but before you do get info on what you are doing first Quote Link to comment Share on other sites More sharing options...

blowit Posted July 1, 2007 Report Share Posted July 1, 2007 Hey guys got a quick question, im in the middle of porting a set of stock cyclinders, What are the 2 ports on the SIDES inside the actual cyclinder and what do they do? also is there anythign I can do to them to help out performance or leave them alone? Thanks A lot Justin Justin, you are going to get strong discouragement from most people and I am one of them. Not because if your willingness to learn but your lack of homework on the subject. They are called books my man, get some. Not saying you cannot do it, BUT if you think for one second that porting is simply smoothing ports out, then that is what we call a fluff and buff job in the industry and is not what we consider porting. The actual cutting itself can be learned in a day but the math and knowledge required is staggering for the DIYr. As I have always taught, it is one thing to take an engine apart and put it back together but taking it apart and knowing how to make it better or faster is a whole new level. I would say best of luck but research always yields a better outcome. When you are done with them, send me some pics and I will see if I can point you in the right direction.

Snopczynski Posted July 1, 2007 Report Share Posted July 1, 2007 Ok, so he is in the procees of porting his cylinders and he is trying to do his homework and find out what to do with those ports right now. When I go to do mine, I am using the race logic templates on em. I am also gonna go over to my motor guys house and find out what does what and see what we can do over the templates that will improve the port job. Modding computers is easy, I wanted mine to be faster, I went into the computer store asked the guy what I needed. He said more memory, he sold me a 256mb card and I went home, took of the back panel of the tower and put it in one of the 3 empty memory slots in the computer and it was faster. I blew it out with air, added an extra fan and put it back together. I always do my homework, but I alweays also learn more as I do stuff and then I can add on to what I am doing. Dont discourage anyone from doing what they want. There was a time when even Jeff from Fast had to port his first cylinder and he had all these questions also.

Thanks A lot Justin they are your transfer ports and yes you can knife edge the bottom of them where the cylinder bolts to the case and work over the upper portion but you need to have the propper tools for doing the job. if you dont own a good set of port tools or own a set but have no experiance with them then it's best that you let someone who knows how to do the job do it. i have always had the desire to port my own stuff but the fear of hammering a set of jugs has always led me to the door of my engine builder...good luck with your porting, hopefully it works out for you because every good port guy started out exactly where your at right now! i just wish i had the balls and cash to do what your doing...lol Edited July 1, 2007 by swrbansheeboy Quote Link to comment Share on other sites More sharing options...
rocketboy Posted July 2, 2007 Report Share Posted July 2, 2007 the ports your referring to are the primary and secondary transfer ports ,there should be 4 of them not 2,they open and close to draw and release emulsifed fuel and act in a similar way as a cam(cams) and valves do in a four stroke engine .you will want the right tools and bits for the job and a should do many hours of research before even attempting to alter them .a 2 stroke engine is like a puzzle and its very easy to screw up and make less power than stock if your unsure...keep in mind bigger ports arent always better ports !!!! not trying to deter yo u fro m learning and experimenting ,but it only takes a second to make a huge mistake if you dont know what your doing .good luck Quote Link to comment Share on other sites More sharing options...
