I have heard somewhat good things on magnum engines, I have all OS engines now and saitos for my 4 strokes but are they as reliable and produce the power of an OS of equal size? Ive been seeing a lot of posts on magnums and thought I would ask for opinions. How is the tuning, if its like the super tigres Ill pass on that. But if there like OS or similar I may try one in the future. Thanks...Jason
