ok i bought a 93 warrior which has a fmf slipon on it but if i gun it from real low speeds it bogs and it has a lil knock so im guessing its not re jetted is there anything u can do without buying new jets or do u have to also how much faster will it be?

 

i put on a power core slip-on on my warrior and got it rejetted right away. I noticed that it cut out and bogged when i revved it. it shouldnt cost much to rejet either just go to a local yamaha dealer and get a bigger jet. i went up 2 sizes (150 currently). its fairly easy to do. it only took an hour to do mine(mainly because you dont have to remove plastic on the warrior.)
