I got all my parts in except the air intake cause noone has one yet. So far I have the Crower intake cam, ESR full exhaust, 15 front and 34 rear sprocket, 2" handlebar risers, removed the rear P-brake, clutch cover protector, new chain rollers, Dynojet programmer, PRM front to rear skids, And a rear cargo carry, and I think thats it. I still need footwells cause after 2 hours the left one broke. I took it out tonight without the cam, cause i just got that in a hour ago, and was wicked fast. I had my brother race me on blacktop and he weighs 60lbs less than me and I still walked by him.

After getting the Crower cam, I took alook at the stock KFX cam and then the crower one for the dirt bike and all I can say is WOW, a big difference by just looking at them. The lift is 1/3 more on the Crower. The cams on the KFX look so blah to me. Next I think I need a exhaust cam casue it look like a small lift. I did happen to drop in a c-clip in the motor. I was telling myself the whole time not to do it and then I just grabbed the cam not thinking and down it went. I pulled it out 5 minutes later with magnet tho. I also use aluminum bolts in the fender holes. Looks geat. i dont have a pic but tomarrow I will have one after I get to the bar.lol.

Sounds nice. I've got a lot of ideas in mind for mine but I'm going to spend this year basically letting the results come in for what's best and then build it into a monster during the winter rebuild.

Got two C'Dales that'll blow it away in power right now decked out so no need to build it yet. Plus I want to see what parts produce the most power and reliability. Good luck though man. Let everyone know how everything goes.

Well I got a couple hours on the machine today after the mods. With the power programmer its good on top butneeds more fuel down low added to the base maps.

Well my brother has the other stock KFX450 and mine with the mods in the first post, well lets say it does almost 79mph. With my brother on the kfx and on a rolling start it just eats his up like nothing and has quite a bit more top speed. This is when he changed his front gear up one to a 15 so hes doing 73.4 or so on top.

That cam makes such a big difference power and torque wise. It feels like the modded yfz I just sold. ( the YFZ had a crower cam, 06 wr450 motor, full exhaust, intake, etc.) I know that the yfz does 82 on the gps up top so its faster but the guy who bought it dragged me on the road with a rolling start and i just walked away from it.

I still have to do a drag from a dead stop cause thats what makes the difference.

I need more time on it just to see how quick it feels. I was trying to putt around to not piss anyone off with the esr exhaust.

Well see later tonight how it does from a dead stop.

How is the lower gears with the 15/34? Have you tried the 14/34? I would like to change rear sprocket for overall riding (trails, dunes, drag race every no and then). So I am just wondering if the 34 or the 36 would be better?

Thanks for all you've done so far

Ihavent tried the 14 34, but if you are gonna ride 2 up sometimes dont go 15 34. 14 34 I know would be perfect for 2 up and great in the trails. All I know is that I will be keeping my 15 34 cause with the cam and esr and PC3 its got more torque to lug in 1st with almost no throttle. I would suggest a 34 rear and then keep the front the same. The 400ex Sprocket is the same one except of the tapered bolts that hold it in. SO you could use that of get one from sprocket specialties but you will be spending some $.
Inthe trail with 2 ppl you are clutchin alot and i dont like it. By myself im fine casue my yfz was geared high and im used to it.
