RE: 4 strokes
I've only heard mixed reviews of the magnums,but the one thing I noticed about them is that they now cost more then they used to. There not really much cheaper now then a Saito or an O.S. I think they're trying to cut into the sales and price range of Saito's and O.S.'s,but I just dont think they have quite the reputation to be charging that much money for them yet. I know it is about $50.00 difference,and that may seem like alot to some people,but 50 bucks isnt alot to me considering with a Saito or O.S. your almost garanteed to have your engine work great as opposed to HOPING your engine is gonna work. Anyway.......I'd rather pay the xtra $50 for the confidence of knowing I have the best and it will not let me down.
If I could only ever have one brand of engine it would be SAITO.
