Ran my F5 SP tonight. First time with the new riser, jets, and reeds in it. WOW did that make it better. Can't wait for it to get cold and see it then, it should really run! Almost flipped it when i throttled her out of this dip in the field by the house. She wheelied right up. I couldn't do that if i tried with the old jets and reeds in. Just wanted to tell you guy i had it out.
