I had a teacher in junior college Dima Elgin of Elgin Cams he taught that you select the proper cam for the application then build the engine to match the cam. Every thing you change you will need to correct something else and so on( the butterfly effect ). So knowledge is key or monkey see monkey do. Here's where I learned and I still refer back to when needed. This book has been in print for over 30 years one of the best books for understanding a four stroke engine , building , tuning. Hope your good at math , I'm not I have a calulator. In the book the Yamaha SR500 is used, not all that different from the Suzuki . Four Stroke Performance Tuning by A.Graham Bell In Dima's 12 week course I was in week seven and on the verge of failing,he said go back and read the book and read it again if you have to. Week 12 scored A- in the class, tough course, tough teacher,great education,that was 20 years ago and still have that book !
