Has anyone tried one of these on the Raptor? I saw one firsthand on a DS650 and it did make a difference, I couldnt catch him!! Of course my jetting is waayy lean but he was fast.... I just wonder if it will work well for the rappy????

 

I havent heard of one yet that made a difference on the Rappy. I have been looking for one myself, but from what I have been reading along the way is that know one can make them work like the Honda 400ex ones.

 

Hey bro....how do you like the sparks exhaust? Thanks!
