I've got one on my 800 and its not much faster or quicker than a stock one.:angry: I have stock carbs and no timing key. I will be adding a 2 degree key soon, but i can't see it making that big of a differance. Maybe twin pipes will help? Are there any tricks to making these run strong?
It revs to 7600-7700. 25/38 gearing, Power Breather, cones removed from air box,430 mains, SW single pipe, reed spacers, stock reeds. I had Lenco reeds in but they were chiped so i took them out. I ran that gearing stock with good results. And i've tried it with and with out the spacers and power breather.
