nice reply !!
will deff take into consideration .. I rode growing up (38 now) ..but not trails ...open fields, pastures, and screaming down the country roads... I got rid of my KFX450 for this bike which had a clutch not bad ...minimal stalls ..kind of want the rekluse more the anti stall feature than auto feature... these thumpers stall out when hot no fun to start... for my type of riding not aggressive the MX suspension even with clickers turned out seem still a bit harsh at the slower speeds... i may look into springs too.. as was mentioed earlier on this thread..

once again thank you for the feedback ...
Wants a "quiet" Db level for the the silencer? seeing them from 94 -98 Db......

94 is the requirement for forestry and AMA tests. I wouldn't buy one unless it said "meets 94db  requirements"

I totally agree that you should avoid the rekluse at least at first in order to master the bike/clutch as-is.   This is why I suggested earlier to go only use the rekluse if youre racing.   What some people arent mentioning is how big a deal good pipe/tune can come into play with eliminating stalling.   The correct pipe (designed for low-end grunt) and a good tune will change the low rpm characteristics of the bike.  

For example I have owned my 07 kx450f since new.   I made the switch over from an 06 kx250f, and believe it or not the 250f was less prone to stalling in the slow stuff than the 450f, it was very disappointing.   Then kind of on accident, i installed a jardine slip-on (needed a spark arrestor to race), and low and behold, as soon as I installed the pipe, the stalling was FIXED!   I couldnt believe it.   Night and Day difference with bogging and stalling. I could take the bike out to familiar sections of trails that I always ride, and sure enough, tight spots that used to require higher RPMS in 1st gear, could now be attacked in 2nd gear, lugging and only a chop of the throttle was needed to spin the rear tire to steer, right off idle in 2nd gear!.     It was that big of a difference.

I love my KX250F in woods.
All I did was change the fork springs (softer) revalved the forks and shocks and give it horns.

I wonder if the KX will lose some it's snap (as in jumping a long or gut or something) by running the Rekluse?  I've ridden a 450 with one and no problems but not a 250.  I know some will not run the Rekluse on 350 or 300 2 strokes for this reason.

Then those guys never set the rekluse up properly from the start. A rekluse will work the clutch better than you could ever yourself.

yzstorkin you running a rekluse?
just read article in Dirt Rider in March issue they say any issues they had, Rekluse has worked out.

@ Jake kxf you re sprung it too? still ok on jumps .. be interested in other mods you have done ... looks like you have a nice place to ride there.

I had a Core EXP on my 09' KTM 250 XC and it was awesome, you didn't need to touch the clutch ever, just work the throttle. It let me run it in deeper in the corners and really helped smooth out the way I rode. You could still modulate the lever for technical stuff like and endurocross course or logs as well.

The only downside for me personally was that it completely took away all engine braking. That sounds like a good thing and it would be on a thumper, but for the way I ride I kind of depend on the engine braking in slow technical sections like rock gardens or quick up and down hill climbs. I never had any other issues with it.

I have ridden bikes with the Z-Start Pro's and didn't like them at all, I hate the way they make the clutch lever feel(mushy under 5500rpm then hard as a rock from 5500-6500rpm, you don't really need clutch above those rpms.) The Core Exp maintains stock clutch lever feel.

I had a look on Race Tech site where they have a spring rate calculator and found my shock spring was correct for my weight, age and riding preference, but the fork springs were too hard. My one is an 06, and on that particular model the bike came from the factory unbalanced (fork spring weight ratio : shock spring weight ratio).

After a particulally tough rocky ride I had enough and took the bike to our local suspension guru. He removed the OEM fork springs and tested them; they were all over the place. The one was quite a bit harder than the other and both were harder than what OEM was supposed to be. He fitted the correct weight springs and revalved (not sure exactly what he did; trade secret ) . The shock was just revalved and serviced. After that the bike was better everywhere. You can see from the video I like to ride deep sand where you want your set-up as hard as possible, but even in these conditon the bike is better; in fact it is chalk and cheese.

The bike is great on the MX track and jumps fine. Only other mods I did was fit bark busters, Hyde sump guard, silicon radiator hoses and a re-boil bottle, which to be honest is a waste of money. Here in South Africa we don't worry about spark arrestors and the bike still has the OEM pipe fitted. The sprocket ratios are perfect for  me as they came from the factory.

thanks guys !

Suspension re-valved and Rekluse EXP installed

only got to rip around the fields by my house but so far so good !! chisel plowed fields no biggie ...
Rekluse ?? i think in the end i will appreciate.
Still used the clutch.. habit .. but was nice to be able to put in 1st and idle ...no stall ... in the chisel plowed feilds i slowed it way down to see if would peter out nope.

next is exhaust i believe ..and don;t worry looking into 96 and below ones ...pref 93

thanks everyone

i say ride the thing see how it is stock and go from there see what makes you uncomfortable and develop your prefrence, myself from riding i found what i like and dont like when i get a new bike i add pro taper woods hi bend bars cut down 1/4 on each side ee hand guards and bar mounts that give a little bit of rise as far as gearing i base that on the terrain and mostly run stock gearing. suspension i have always had mine revalved and sprung for comfort as far as a rekluse goes id onl get one if i stalled the bike alot otherwise get clutch work down (i also ride a 250 two stroke tho so re start isnt a difficult issue) so mabye use that money for the rekluse on something like an 18in rear or a coolant recovery system or a more comfortable seat than stock. as far as a pipe ive always stayed stock except on a 2 stroke but on the 4 strokes ive had were older and got a pipe for weight savings now days the bikes are light not very loud i wouldnt worry about that unless you need a spark arrestor.

Been trying to figure out coolant recovery system? picked up a KDX bottle ... won't work not enough room...

Bike has been revalved , Rekluse EXP installed, .................along w/ O ring chain and TM Designs chain guides ...thanks bentbars

Picked up a FMF Q4 and FMF Power Bomb...thanks drzadam

I have made a few test rides with the suspension and already likng it along w/ the Rekluse...next will be to see how the exhuast performs ..already like the quieter sound.

msr makes them

I just went from an 09 YZ450F with a Rekluse and all geared up for woods to a 12 CRF250R. The 250 for tighter New England woods is a FAR better bike BONE stock standard then my 450 ever was. You'll enjoy it and a woodsboogered 250F MX bike I believe will be a weapon for sure.

the kx is 13/50 on gearing .. which i think will be just fine ... can't wait to try it out ..
