My friends and i tried some of the magnum ds30 since the price is so attractive. ds30 gives great power on my friend T700 LE which has OS 91 but i have a bit of trouble tuning my ys 91 sr. Any body know the needles position for this combonation of engine and fuel. I'm running this on the N9. thanks

Well lets see, the needles on the ys's are touchy so try starting at about 2 turns from open on both and then start w/ the mid range first then the high end. Go only 1-2 clicks at a time when adjusting for a nice warm not at all hot back plate. When you hit the sweet spot you will know it. The DS now days is just like other fuel in tunning but runs a little cooler. Have a little patience and it will treat you right, its good stuff.

Keep ur head out the dirt only in the grass
