From stock to slightly modded made a significant difference especially in top speed.

A friend has made these performance mods and the difference is night and day

plug out of the can
EHS air box cover
fuel controller
33 tooth rear sprocket

got some photos this weekend on our 190 mile ride thru the Wisconsin state forests


when they were clean


20 miles of misery





and the new KFX uses allot of fuel when mods are made.. about 55 miles on a tank and then

the first time ...out of gas


then again after tanking some out of my dessert tank






a few more shots

Most likely he's talking about the spark arrestor. The thing is pure restriction and a joke. But does make it pretty quiet w/it in.

There was a very significant performance increase and puts it either on par or better than other 450s that have similar mods.. The gearing change made it much more enjoyable for riding in the 50 to 70 mph range.

"Plug out of can" is pulling the spark arrestor out of the stock exhaust system.

Even w/ my Setup it's still very quiet....

But to me, It has been like getting 2 new quads..

1st was the stock KFX. Witch we all know what that was


2nd was w/ the mods...

There is a night a day difference between the 2.....

Sure like to try out that 32t... wounder if ya would notice the change in just 1 tooth????
