I've put them on my 85 Phazer ... You have to do alot of playing around to get them to work , like I had to go down 3 jet sizes from stock , should go down 1 more . About the HP ... ? *I don't know , but it did wake up the mid range and I'm getting about 2 more miles per gal . As for is it worth it , I would'nt use them again .... to much playing around ! and now they are both leaking fuel . I hope this helps ya out . *http://www.snowmobileworld-s2.com/forums/iB_html/non-cgi/emoticons/biggrin.gif
