Satsol67 Posted October 20, 2006 Report Share Posted October 20, 2006 I am very intrested in learning how to do the home porting as well. I am in the same boat as alot of other people and dont have the 500 bucks to have it done. I would like to try it out on the set of cylinders I have laying around. So if anyone would be so kind to post the templete that would be great. Plus it would be helping others learn. Quote Link to comment Share on other sites More sharing options...
rocketboy Posted October 20, 2006 Report Share Posted October 20, 2006 without a high speed right angle micro die grinder of some type yo uwill never get into the transfers accurately and make the power even if yo u did know what and how to do it ,theres a lot more than a simple overlay template when it comes to porting engines Quote Link to comment Share on other sites More sharing options...
blak banshee Posted October 20, 2006 Report Share Posted October 20, 2006 I read on the net somewhere a while back that the rough surface in the port creates turbulance that helps with the atomization of the air/fuel mixture after it goes through the carb. Polishing a 2 stroke could hinder performance. It was an article from a guy working on his blaster engine. Maybe someone else read this too?

RIPPEN Posted October 20, 2006 Report Share Posted October 20, 2006 By the time a guy buys the templates, tools, cyl's to replace the ones he F-ed up, and time he has spent.. He could of had SEVERAL sets of cyl's that RIP done by a good builder.. Like some have said, I belive porting is a art form.. So I would leave it to the artists..

Satsol67 Posted October 20, 2006 Report Share Posted October 20, 2006 Why is it such a big secret on porting? Why dont people post pics of good port jobs? All that I have seen posted it the ones that are messed up. If it is so hard to do then posting good pics shouldnt be such a big deal.

JET 99 Posted October 20, 2006 Report Share Posted October 20, 2006 why doesnt everyone build top fuel drag cylinders im sure there is money in it! why do some work with hi explosives? why do some drive heavy equipment? hell its got a steering wheel and pedals. do you go out and play with the transformer out on the telephone pole? it is just a few wires..... i m not picking a fight but i hope you get what i am saying.... in work on machinery lathes, machining centers, grinders, and gmaw weld. (machine repair at a machine shop).. I have access to enough machines to probably make an engine, but they run production and i dont have all the fixture and jigs, the knowledge, practical experience, or desire by an old set of cylinders and port those. play with some stufff you dont need....ie a good set of cylds. keep the ones you got on your motor on your motor until you think you have a set that will work good luck!!!!!!!!!!!!!!!!!!!

BansheeRider71 Posted October 20, 2006 Report Share Posted October 20, 2006 Though I dont own a Banshee yet, I do own a YFZ 450 that Im gonna have ported and to be honest, Im all for doing it yourself because though you have to spend alot of money you still save a lil bit, But I would rather have a pro do it because thats all they do and if they mess up its on them, and some people can do it good themselves others like me like to send them to a pro, its all about preference, but I would reccomend having a pro do it over the do it yourself way on this.

blak banshee Posted October 20, 2006 Report Share Posted October 20, 2006 Isnt the template only 2 dimensional? and a port job is 3 dimensional. The shape of the port job is just as important as the removal of material. There is a science behind the shape to maximize velocity of the air coming in, not just the volume of air. Am I correct?

I wasnt suggesting that you experment on your good ones. I have a set with a bore can be used again. I would never play around with my only working set. (that would be stupid) But for those like me that have some to test on with more people trying and showing thier progress others would learn. Course this is just my opion.

I believe that the intake benefits from turbulance but the exhaust ports get polished Quote Link to comment Share on other sites More sharing options...
nameehsnab Posted October 20, 2006 Report Share Posted October 20, 2006 I just did my cylinders with the Racelogic templates and they came out great. Just follow the directions. It took me about 10 hrs to do both cylinders. I have not had the head shaved or done the transfers yet. The directions tell you what to do there as well. I didn't find any part of the process difficult. I think I probably rosted my Dremmel a little to much but the results were worth it. I compaired my cylinders to my brother-in-law's and mine looked better. My cylinders were also cymectrical and identical where his were not. I will post pics of the cylinders later when I tear down the engine to do the transfers. Quote Link to comment Share on other sites More sharing options...
ferociousllama Posted October 20, 2006 Report Share Posted October 20, 2006 Everyone I have heard from that used the port template has had great results. I also hear that a professional port can get more power. My Banshee is already faster than all my friends toys and I don't need it to race or anything. I just want to be able to go fast when I want to. I have ported 2 strokes before and they came out great. I have the tools and knowledge of how to port so I can't justify spending a bunch of money for someone else to do it. I understand that parts are expensive so no one wants to do it themselves. I would much rather do it my self and mess up my cylinders because I can get new ones for less than a port job would cost. So, anyone who has templates please email them to me or post them or something. If you want money or something let me know and I'll paypal it to you.

nameehsnab Posted October 20, 2006 Report Share Posted October 20, 2006 No payment is necessary. I will scan them and send them to you. You have to make sure you print them @ 100% and on some kind of stiff card stock or something. Sent you a message. Quote Link to comment Share on other sites More sharing options...

I am not for sure but, I would figure that a crank spinning at 9000 to 10,000 rpm would be enough turbulance. this is what do it yourself porting looks like a real mess http://www.bansheehq.com/forums/uploads/po...-1161147458.jpg That is some sweet drag porting. I am going to give that a try. :beer: Quote Link to comment Share on other sites More sharing options...

But when you have all this banshee crap laying around in your garage, why not tear into them with your fancy-pants tools & crap?
