i have a 07 kfx 700 and i plan on putting exhaust and a jet kit on it. what exhaust would give me the most H.P. gain?

 

I have a 06 v and I've been told that a 2 into 1 Muzzy makes good h.p. Also the dual HMF system works good as well. The Muzzy is said to gain the most on the bottom end to mid-range where as the dual HMF's are said to gain most on the mid-range to top end. I have not decided between the two yet. Remember to jet up and the 12 hole airbox mod with a K&N or Twin air filter will really wake up the big V twin. Oh and you cant go wrong with a yoshi exhaust system either! A Dalton "blue" or EPI "pink" spring for the clutch will stir the big bike up as well and you can get them off the net for around 20-25 dollars. The complete clutch kit is more but alot of people just do the spring mod first along with the exhaust and jetting up. Hope this helps!

 

ok thanks that really helped alot. but can u explain the 12 hole air box things? i know more air helps alot but what do u mean by twin air fillter? is that two seperate air boxes? or just twin air fillers in the same box? thanks

Twin air makes the aftermarket filters just like K&N. Once you put the exhaust on and jet up there is a mod called the 12 hole airbox mod that consists of drilling 12 -1" holes in the airbox. There are pictures of this mod on kfx700.net. K&N or Twin air are both good filters and you cant go wrong with either. Also when the 12 hole airbox mod is done yo need to block the main air duct into the airbox off because it will create turbulance in your airbox. The air will get to your airbox by way of the 12 holes once this mod is done! Hope this clears up any questions.[img]i/expressions/face-icon-small-smile.gif[/img]

 

yeah thats helped thanks. but i just bought this bike new about 4 months ago and it still has a full one year warrenty on it. will these mods void the warrenty? or will it void the warrenty for just those parts

 

Have a 04 Force that I gave to my son and I ride a 750 Brute.These mods will help but I would save your money.Even with these mods you will be looking at the taillights
of the sport quads.I did the clutch kit-complete and it helped a little.Ride it the way it is-good low end -bad midrange-O.K. top end.Good trail machine but no rocket but will be alot of fun.

 

Check out kfx700.net and you can read about the mods on there. I havent done any of the mods to mine yet so I cant give you any evaluations on how good they work, but from what they say over there is that they help pretty good but like Force said , it is never going to be a pure sport quad but they are an excellent trail machine , sort of a jack of all trades but a master of none if you get my drift[img]i/expressions/face-icon-small-wink.gif[/img] But seriously, check out that web sight and let me know what you think!

 

yeah not really trying to get it to be the fastest bike but i would like a little more speed and be able to hang with some raptors. i will check that site and get some more info. but one more question. after these mods aare done and i get my cdi box in there will i need to change the grade of gas i run in it? i run minimal 87 octang gas now. will running a higher grade help any? thanks

 

One thing it is the master of is bringing that front end up at low speeds.

 

yeah i agree with u on that one. it has the most torque then anything else i have ever ridin. which also make it hard to race because its hard to keep the front end down.
