I've got a 1995 warrior that is completely stock except for the replacement styled K&N air filter. It has stock exhaust and would like to keep it that way just for noise reasons. I would however like to get a little more power. I have read the pdf on the dynojet web site, and it says that you can up the main jet size and still run stock pipe. I'm not opposed to whackin a hole in the air box lid but am wondering if I should buy the kit for 50 or so dollars or just buy the next few sized minkuni replacement jets at about 5 bucks apiece? They also say you need to change the needle. Is the needle a different design to fit there jets or is it something else?

 

do yourself a favor go down to your local yammie shop get the jets you need it will work best, also becareful with the mods on the airbox warriors are real tricky they won't run right if you let to much air in the bike will lose all throttle responce at low end, I had one and shot abunch of holes in it and really screwed it up had to get a new box for it for it wouldn't run at all with the box removed.
