Going to Taylor Park...jetting?

Okay so i'm back to the stock exhaust and the airbox mod and really don't have a baseline for 500-1000 feet anymore.

I was riding with:

Main 142

Pilot 42 or 45 can't remember (one step above stock)

Needle-3rd clip

Screw- 1.5 turns out

I was riding like this with a 250r exhaust and full airbox mod and it ran great, but after looking at the plug it seems to be too lean. I know people have said go to a 152 main and drop the needle to the 5th clip, but that just seems way rich and now I want to run the stock exhaust so that will change it either way.

So what should I be looking at for Taylor Park, CO (7,000-13,000 feet).

Thanks :thumbsup:

So what should I be looking at for Taylor Park, CO (7,000-13,000 feet).
Start by using 9330 feet, the elevation of Taylor Park Reservoir. There is no place in the Taylor Park area lower than that. Almont is at 8,000' and Gunnison is 7,600" or so.

Is the exhaust truly stock or has the diffuser been drilled or removed?

Try a 42 pilot, clip on #3, and 130 main. Fuel screw in the 1.5 - 2.5 range. Bring along a few main jets larger and smaller, but pay most attention to the needle.

Ask Eddie in the jetting forum...

My exhaust is truely stock and will not take out the baffle, eventually I may do the diffuser but not before this trip.

Thanks Ramz I will bring a 130, 132, 135, 137, and a 128. I might even buy the 250r needle, but then that might change all the numbers.

The reason I say 7,000 is because we are heading to Hartman Rocks one day out of the week and I think it is pretty close to 7,000 feet. Maybe it's more like 7,800 feet.

      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??
