Big 3 Mods

[goldp1976]

I recently bought a full DASA 13" exhaust, Fuel ATV intake and a PCIII. I used the Fuel ATV map. Before I modded my KFX, I raced my friend with a 450R with slight mods and we were dead-even. We raced numerous times on long runs to confirm on a paved road. Today I raced him again on a paved road, but this time I have the Big 3 mods that cost over $1110. I beat him by a consistent 5 bikes. I was a little disappointed since I thought I would pull him by 7-8 bikes and continue to pull away, which I didn't. I think the map is off since it feels a little sluggish and I'm not seeing the tremendous gains as everyone else is with these three mods. I ride at 6,000 feet elevation which makes a difference, but so does he. I also notice I have to quickly short-shift the quad to make it run its best because if I wait to shift until I hit the high RPM's I will lose enough power to nearly lose the race.

How many bikes should the Big 3 mods make compared to a stock KFX running a normal drag to 5th gear? </span></span>[/b]

I thought it would be 7-8 but I was either wrong or am running a less than ideal fuel map.

The big 3 are the starting point,,, as fare as power I don't know but if you don't do them you will not progress much further in your quest.


DO the basics and then start working for your 50+ HP

Ummm 5 bike lengths seems like quite a difference to me . I'm where you are and i think me next step is gonna be cams. everyone says the stock cams are really sad, I think thats gonna help you with the power falling on its face in the higher rpms.

Sounds like a pretty good gain to me. You can have all the horsepower in the world, but unless
you change the gearing to accomodate your newfound power your not going to be any faster.
You'll accelerate to your top speed quicker,but thats it.
A 50 horsepower bike will have the same top speed as a 100 horsepower bike as long as they have identical
gearing, and both bikes rev out to the same RPM.

If you want the ultimate in straight line speed get a banshee.
$1110 will take a 35-40 HP stock banshee to 65-70 HP.(Porting, pipes, and carbs)

if u want more speed u should change ur gearing up
15 front 35 lower rear

did the 3 mod plus cams and still dissapointed,,, it will be time for a piston rebuild soon so the head will get ported too

Wow are you series? How does your KFX do against the other 450's dragging at the hill or on the flats?
I'm just curious because I haven't ridden mine much sense I bought it 2 months ago.

Did you like the power the other 450's had compared to the kfx or were they all about the same?
