what can i do to make this thing faster

shorten up the header pipe, put a couple more base gaskets in to raise the port timing and either split the head gasket if it is a 3 piece ( i cant remember) or have the head milled a little only costs about 50 to 75 bucks to get the head done. This is good for about 10 to 12 horse and it is still very reliable.

10 to 12 horse and it is still very reliableremember this is a 550 fan. think those numbers are a bit high.

This is a question that keeps coming up. Would like to quicken up the wifes a little, but it runs so well I hate to touch it.

yes my old super sport ran amazing but i always thought it could use a trouch more zip... as a friend of ours says if you need a fatser machine buy one dont inker... ehh anyways... you could try a cluth kit on it i ha dthe name of a good one but i cnat seem to find it so thats not much of a help... but its a 550F so im not aware of nay pipes or other items that would be avaliable for it i thin your best bet is to go clutch kit... by the way what year is it? and hwich sled is it? becuase i know my 550 i was bale to crank about 80 out

This winter we dynoed one with that done and thats what we got. I could not belive it myself.

you dynoed a 550 fan cooled? if your bored you can dyno my sled. :)

Thats a pretty impressive increase for a 550 fan. Hate seeing gaskets doubled up though. What was done as far as jetting with the new set-up?
