I just made a suggestion on the 'Suggestion Box' section of TT that we have a general Porting/Performance section for everything to do with 2 and 4 stroke performance mods. This site is regarded as a bible for suspension knowledge, and we have a dedicated Jetting section so why not do the same with Porting/Performance knowledge? There is no shortage of very knowledgable people on TT and there is heaps of good info here but it is scattered all over the place. I'm thinking that topics such as 2 stroke porting, 4 stroke porting, ignition timing, compression ratio, fuel properties, valve design, and head design could be discussed in one forum and still have relevance to most makes and models. I have been trying to understand 2 stroke porting for about a year now and have found lots of great info here and elsewhere, but it is really difficult to find. I have read heaps of books and played with cylinders in the shed but it would be great to bounce ideas off people, and hopefully get advice from others who are more knowledgable. What i'm hoping for is a section which really gets into the technical detail of these topics... I know we can do it! If are interested in this idea show your support by replying to my post under the Suggestion Box section on TT. Thanks Dave.
