Stumped... Help on Jetting a CCC Mod CA 250X

So a couple months ago, or maybe around May, I performed all of the CCC mods, except for the R's cam. Recently I bought a Dr.D ehaust system, but that didn't recommend any jetting changes, so I left my jetting alone. However, after I performed these mods, my bike has always had a horrible bog as soon as I cranked the throttle from low RPMs... Here's how everything, after some tinkering (but to no avail), is set up:

40 Pilot

150 Main

Needle - 5th position from top (1 LOWER than recommended)

55 leak jet

Pilot Screw about 1 1/2 turns out

Air Filter Backfire Screen IN (stock airfilter)

Air Filter box cut to Honda's specifications (on the line)

I ride usually in 60-75 degree weather

at approx. 2000-2500 ft

I took out the carb when I did all these mods, and I also removed the smog pump (CA model). The bike runs great other than that horrible bog... Any ideas? I'm truly stumped, especially after tinkering for 3 months but having nothing change for the better. :cry::cry:

I also live in So Cal and have the X. IMO you need to go to a 42 or 45 pilot and the clip in second grove up from the bottom to raise the needle more (richer). Pilot screw 1 1/2 to 2 1/2. The MJ sounds right. The bog is just a lean spot as you raise the slide. Good luck.

thanks for the help!

I am in Norcal, but ride about same temps and altitude. I run a 45 pilot and a 152 main, needle on the 4the clip. Everything else is identical to yours.....

      Hey I have a crf250x 2005 I was riding today in top gear flat out and when I slowed down blue smoke just poured out the exsaughst then I happened to open the air box lid and saw it has what looked like engine oil in it then took out air filter and noticed that there was splatters of engine oil on the inside and that and the channel that goes to the carby had engine oil all over it.
      Also bike got a top end rebuild 15 hours ago
      The engine still runs good and sounds normal
      why would this be happening on a resonabley fresh engine

      Hey everybody. Quick question for y'all. I recently went riding and about halfway through my ride my motor seized on my '07 CRF250X. I haven't investigated it much but I checked the oil when I got home and there basically was none so I'm assuming that was the culprit. There weren't any metal shavings in the filter or on the plug either. At this point I'm trying to decide to rebuild the motor or just sell the bike as is and let the next buyer deal with it (they would know the deal obviously.) I feel that I'm pretty mechanically inclined but rebuilding a CRF engine is a bit out of my league and I assume paying a shop to do it would put me out more money than the bike is worth. So, I have this question to ask; what would be a fair price for a pretty dang nice shape 07 CRF250X, with a seized motor with an unknown extent of internal damage?

      I have two rides in on my new Rekluse auto clutch and I have to say I'm very pleased. The install wasn't hard, but was pretty much a all afternoon sort of project. I also installed a left hand rear brake kit and a two finger cluth over-ride with the adjuster on the perch (which I rarely seem to need). It has all worked great right from the beginning. After struggling to get up a tricky hill in first gear, I tried it in second and the autoclutch helped me clean the hill easily. Not having to worry about clutch action in techinical sessions has also eased fatigue and just made it more fun all the way around. I ride mountain bikes alot, and having both brakes up on the bars has also been nice as it makes for a set-up just like the bicycle - in fact I like that as much as not having to worry about clutch manipulation. The brake on the bar is especially nice on tricky downhill sections where you need to paddle, such as nasty rock/rut stuff. So first impressions are that it was worth the investment -making the ride more enjoyable and easier at the same time!

      I was driving the bike for 15min or so and all of the sudden the bike stalled. I tried starting it again with no luck. I took the spark plug out to see if there is spark so i ground the spark plug to the frame and there is no spark. I even put a new spark plug in the bike and still nothing. Any ideas what i should check??
