crustydemon Posted February 6, 2011 Report Share Posted February 6, 2011 You need to go up down and sideways. Seriously, there is more to it than just that and if you dont know what way to go you shouldn't be touching them at all. I'm not trying to be mean, just trying to be truthful.

Larry's Shee Posted February 7, 2011 Report Share Posted February 7, 2011 Contact member Sloryder on here. He'll hook a brottha up!! You would be better off reading Gorden Jennings and H. Gramm Bell and if and when you understand 90% of it all, then you might be ready to tackle a home port job. It's easier to jack it up than to do it right. In the end it's up to you.

armyvet Posted February 7, 2011 Report Share Posted February 7, 2011 im all for doing stuff yourself but ONLY after you have a basic understanding of how porting works.Its not exactly rocket science or a "secret" black art like some will lead you to believe but not knowing what your doing can turn a good cylinder into a paper weight..lol But then again i had a old boss tell me"people that have never f@#ked up have never done anything" so.... i say leave certain things to the pros cuz i know my limits Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted February 8, 2011 Report Share Posted February 8, 2011 Contact member Sloryder on here. He'll hook a brottha up!! Yea go go read his old posts and threads. Started out asking what ports are and ended up a porting professional. The original poster hasnt even said weather he is going to be running a spacer plate or cut domes. I guess it doesnt matter, it all ports the same. Hog them baby's wide open. Quote Link to comment Share on other sites More sharing options...
forumsearcher Posted February 11, 2011 Report Share Posted February 11, 2011 Im gonna port myself a 4 mil sleeve, do i need to go up with the port or go down with it to match the piston ports? You need to do a lot of reading before attempting any porting. I totally agree with reading the 2 stroke porting book by A. Graham Bell. I read it twice then decided to just but the Race Logic porting templates. The templates make it easy to port a stoke stroke motor, and it helps teach you what a correct port window should look like. In fact these templates will help setup your exhaust and intake ports for a 4mil bike. By the way, if you are going to bother buiding a 4mil bike you need to get a cool head with recessed domes. You are better off with the stock crank that using the lame ass spacer plate. I know from experience. The transfer ports are a pain in the ass because you do not have the proper tools to port them properly. I just finished my 4mil bike with my home porting, so I wont totally discourage you from going at it yourself. I should know in a couple weeks whether or not it runs well or not. Here is some reading for you that I have come across, there is tons more out there.... Try to resist the urge to post questions before searching for a few hours on what you are trying to learn. I assume you likely need to do a little reading on degree wheels in order to understand some of the details in these posts. http://bansheehq.com/forums/index.php?showtopic=136007&st=30 http://bansheehq.com/forums/index.php?showtopic=132925 http://bansheehq.com/forums/index.php?showtopic=140120 Quote Link to comment Share on other sites More sharing options...
